1 INTRODUCTION
The SENSIT vehicle detection system facilitates accurate measurement on
occupancy of individual parking spaces in car parks, and on-street parking spaces.
This information can be used to guide traffic to free parking spaces but can also be
used for on-street parking enforcement and overstay detection. For on-street
enforcement the number of occupied parking spaces can be compared with the
number of payments realized by the pay station. For overstay detection the system
alerts instantly a parking officer to the presence of nearby overstaying vehicles.
Based on this information you can exactly determine which space to enforce.
All the SENSIT vehicle detection sensors are featured with detection and
communicate wireless, creating their own network. The SENSIT sensors do not
require power wiring, in contrast to conventional systems that require wiring
throughout the car park and mounting onto the ceiling.
Easy installation of the sensors is guaranteed. Once installed no maintenance is
required for years. The actual status (occupancy) of the sensor is transmitted to the
Relay Node, which is part of the wireless mesh network.
Different types of ruggedly designed sensors are available to accommodate
installation in indoor car parks, on-street spaces and road surfaces.

ARCHITECTURE
The actual status (occupancy) of the SENSIT sensors is finally collected by one or
more SENSIT Gateway. The SENSIT sensors transmit their status via one or more
Relay Nodes to the SENSIT Gateway. The SENSIT Gateway (formally known as Data
Collector) is the interface between the wireless sensors network and the SENSIT
Interface Software running on the server. The SENSIT Gateway transmits status
information about the sensors to the server using TCP/IP via Ethernet or GPRS
communication.
Figure 1: System Architecture
For a parking site you need at least one SENSIT Gateway, a Relay Node and a SENSIT
per parking bay.

THE SENSIT SENSORS
Four types of ruggedly designed sensors are available to accommodate installation
in indoor car parks, on-street spaces and road surfaces. Until recently the standard,
most used, SENSIT Sensor is the SENSIT IR. For regions with lots of snow the SENSIT
Flush Mount is designed to withstand frequent snow ploughing. The SENSIT Surface
Mount is designed for indoor car parks or roof tops where drilling is not allowed.
For now all types will be available, in the future the standard SENSIT IR and SENSIT
Flush Mount will be replaced with the new SENSIT IR Flush Mount sensor.

SENSIT GATEWAY
The actual status (occupancy) of the SENSIT sensors is collected by one or more
Gateway. The Gateway is the interface between the wireless sensors network and
the SENSIT Interface Software running at the server. The Gateway transmits status
information about the sensors to the server using TCP/IP via Ethernet or 3G mobile
communication.
For a parking site you need at least one Gateway, a Relay Node and a SENSIT per
parking bay. One Gateway is required per 250 parking bays. All Gateway must be
separated as far as possible from each other, preferably at the remote corners of the
site.
2.4.1 THE GATEWAY
The Gateway can be installed virtually anywhere due to its IP65
weatherproof housing and embedded 3G wireless modem. The only
requirements in case it is uses the mobile internet are; an AC mains
power supply and that it should be installed within reach of the
SENSIT wireless network.

2.4.2 GATEWAY COMMUNICATION BACKUP
When both connection means are in place; as well Ethernet as the 3G modem by
default the Gateway will connect via the Ethernet to the SIS. When the Ethernet
connection fails the communication automatically will fall back to the 3G modem.

2.4.3 GATEWAY EVENT BUFFER
Furthermore the Gateway is equipped with an event buffer to store up to 24k
events. This memory stores the events in case both communication means
temporary fails. As soon as the communication is restored the Gateway will transmit
the buffered events.
2.4.4 SENSIT BACKUP BATTERY
The Gateway can be completed with a backup battery to make

ADDITIONAL EQUIPMENT
Additional equipment is available to expand the functionality of the SENSIT system.
2.5.1 ELECTRONIC PARKING LICENSE
The Electronic Parking License (EPL) physically is a
device that is positioned inside the car. Whenever the
car stops for a specific period of time it considers the
car to be parked and it will look for a wireless SENSIT
network. If a network is detected, it will make itself
know to the network. Its unique EPL identifier is
registered at the server with SENSIT Interface Software (SIS). The SIS is triggered
when parking bays that require a license change status (become occupied or free).
When such a parking bay is occupied the system will calculate the odds of the
parking bay being occupied by an unauthorized vehicle.

SENSIT INTERFACE SOFTWARE
SENSIT Interface Software allowing easy system integration into enforcement, traffic
guidance or parking guidance management application. The main features of the
SENSIT Interface Software to help you and make easy system integration possible
are:
x Installation
x Configuration
x Basic administration
x Integration
The SENSIT Interface Software enables easy installation of the wireless sensor
network. Once the network and sensors are installed, the sensors will automatically
appear in the software. Configuration of sensors to specific parking bays, parking
zone and parking lot can easily be realized.
Additionally the software configures and monitors communication of the SENSIT
node network. It monitors the data transfer between the sensors and the SENSIT
Gateways. Moreover it also analyzes communication reliability of the sensor network
in a graphical map, automatically alerting areas for maintenance.
Easy integration can be done via SOAP, REST or REST Hooks interface.
SOAP or Simple Object Access Protocol, is a protocol specification for exchanging
structured information. It relies on Extensible Mark-up Language (XML) for its
message format.
The SOAP interface can query data from the SIS using the http(s) interface, the found
data is returned in a XML description format.
Representational state transfer (REST) is a simple stateless architecture that
generally runs over HTTP(S). REST involves reading a designated Web page that
contains an XML file. The XML file describes and includes the desired content.

4 RELAYNODETOOL
The RelayNodeTool software is developed to get a good estimation of the needed
system components; Gateways and Relay Nodes. The estimation of needed
components is based on drawings of the site. In this way you are able to get a good
idea of the needed components.
In this example we are going to design the SENSIT system for two segments; the
parking basement and the outside parking terrain at the Nedap Headquarter office.
SCALED DRAWING
First get a drawing of the parking lot(s) and find out if it are open areas or closed
(indoor) areas. Try to get information about mounting locations, like lampposts and
poles for Relay Nodes and power and internet for the Gateway. Below you can find a
map of the Nedap Headquarter office, with its parking areas.
Figure 2: Example drawing of parking lots.
The drawing of a segment can be copied out of the larger map e.g. via the standard
Snipping Tool of Windows.
Figure 3: The Basement and the outside area.
Note
Please keep in mind that
with help of this
RelayNodeTool you can
determine the needed
components, but it will
always be an estimation.

4.4.2 SET THE SCALE
Also Set the scale, this location is a parking basement with a roof, large concrete

we advise to reduce the range with about 20%, so set the range to about 20m e.g.
the width of 8 parking bays.
Figure 12: RelayNodeTool: Scaling of the map.
4.4.3 PLACE THE GATEWAY
Because this basement parking area is half open we can use the Gateway of the
open area, so we don’t need to add one for this segment.

perform the segmentation according the
installation plan and calibrate the SENSIT
sensor.
SStep 7:
Glue curing
Leave the glue dry for at least 4 hours
before vehicles are allowed in the parking
space again.
Note
Ensure excessive glue is
removed from the bottom
black core part of the unit,
as this will make it very
difficult to replace the core
part.
For non
-permanent
mounting only glue the ring

17 SENSIT INTERFACE SOFTWARE
INTRODUCTION
The SENSIT Interface Software (SIS) enables easy system integration into an
enforcement, traffic guidance or parking guidance management application.
The SENSIT Interface Software enables easy installation of the wireless sensor
network. Once the network and sensors are installed and calibrated, the sensors will
automatically appear in the software. Configuration of sensors to specific parking
bays, parking zones and parking lot can easily be realized.
Additionally the software configures and monitors communication of the SENSIT
node network. It monitors the data transfer between the sensors and the SENSIT
Gateways. Moreover it also analyzes communication reliability of the sensor network
in a graphical map, automatically alerting areas for maintenance.
The SENSIT Interface Software is installed on a hosted server, so no IT infrastructure
is required at the client. The software application can be approached with any
modern web browser that supports Java can connect to the software application.
Each sensor site has a site specific URL indicated in the following way;
https://sitename.nedapparking.com
USERS
Start the web browser and enter the SENSIT Server hostname. A login screen will
appear.

MAPS
The SIS is more map orientated. The Maps will show the actual parking lot status on
an overview map and in more details. The SENSIT are placed on the map and their
colors indicate the actual status. The SENSIT and other nodes can be placed on the
open street map automatically when the GPS coordinates of all nodes are provided.
It is also possible to configure your own map (SVG-file). See chapter 17.8.4 how to
configure the overview map.
Figure 45: Overview map
The Maps has four main function:
1. Parking, showing the occupancy of the parking lots.
2. Enforcement, showing violations and overstays at the parking lots
3. Analysis, showing the Wireless SENSIT Network status, the segmentation
and the sensor details.
4. Configuration, makes it possible to move the system component into the
right location at the map.
17.5.1 PARKING
At the parking map you can find the number of occupied and available bays. This can
be showed for the whole system or per individual parking lot. At parking lot level the
user can select a bay to get some more details and to individually deactivate a bay.

the system or a specific sensor.
The network view indicates the uptime of every individual SENSIT component. Also
at the overview map the number of SENSIT components with uptime issue are
shown.
Also at parking lot level the individual SENSIT components are marked red when the
uptime is too low. Below an example of a just installed parking lot were all bays,
Relay Node and Gateway indicate a poor uptime.

vehicle with EPL hardware stops moving for a specific period of time, the EPL
considers the vehicle to be parked. In that case, the EPL hardware will search for a
SENSIT wireless network. If a network is detected, the EPL will make itself known to
the network. As a result the unique EPL identifier is registered within the SENSIT
Server system. The user of the EPL App is doing the same, it activates the parking
action with it smartphone.
When a parking bay that requires a license, becomes occupied, the SENSIT system is
notified. The system will calculate the odds of the parking bay being occupied by an
unauthorized vehicle.
17.6.1 PERMIT ADMINISTRATION
In these screens all permit administration is performed. A permit is issued to a
person and it can be a hardware EPL or an EPL App installed on a smart phone.

a need for a maximum time limit for free parking. The menu 'Overstay configuration'
allows you to set several overstay parameters.
Figure 67: Overstay configuration
System overstay settings
With this option the global overstay function can be enabled. The settable Allowed
parking time is the overstay time for all SENSIT sensors defined at the SENSIT
Interface Server. This setting determines how long a parking bay should be occupied
before an overstay situation occurs.
Overstay verification settings
When enabled, the SENSIT Interface Server will ask the SENSIT sensor if all state
events are received in case of an overstay. The last state event message is
transmitted again to the SENSIT Server to verify the overstay.
The Max number of retries (max value is 5) can be set. If an overstay verification fail
it retry to receive the last state event message. If the final overstay verify attempts
fail an unverified overstay event is generated.

17.8.6 SENSOR CALIBRATION
To ensure reliable operation of the system the SENSIT sensors should be calibrated
before commissioning. Calibration values can be set for the magnetic detection in
each axis (x, y and z). Default calibration values are 50 mGauss in each axis. The
default value for the IR sensitivity is 9, the maximum. The IR sensitivity is only
lowered in case of a ceiling or other coverage of the SENSIT sensors.
Figure 68: SENSIT sensor calibration
SENSIT nodes can be calibrated individually. This by entering the Node ID of the
specific sensor you want to calibrate into the field 'Calibrate node number'.
Alternatively you can calibrate all nodes or the nodes from a specific parking lot.
When you click 'Calibrate all nodes' all SENSIT sensors in the network will
automatically be calibrated.
Click the 'Calibrate' button to start the calibration. In the menu an update message
will start to keep you update on progress.
Incorrect occupied spaces can be indicated if a vehicle parked in the neighboring
parking space activates the magnetic sensor. If the percentage of incorrect occupied
(so actually free) is too high over the parking lot, the magnetic values can be
adjusted by selecting a higher value e.g. 60 mGauss. If the percentage of incorrect
free (actually occupied) spaces is too high the sensitivity of the magnetic threshold
can be reduced to lower value e.g. 40 mGauss.
17.8.7 DISPLAY
Display Configuration
The 'Display configuration' screen allows you to control a display via the node
network. This without any physical communication wiring. Only a power supply is
required. The communication with a display is realized via a display node. Note that
this functionality is only available for specific displays. Contact Nedap for more
information. The display node is part of the network and can therefore communicate
wirelessly via the node network. A maximum number of 2 displays can be controlled
in a wireless mesh network of 500 sensors. Use of more displays will increase the
communication latency.
The update of a Display can be enabled and the update interval can be set. A choice
can be made either to subtract the full threshold from the display value on forehand
or to set the display at zero when the threshold value is reached.
Note
The SENSIT nodes can only
be calibrated when the
specific bay and
neighboring bays are not
occupied by vehicle. When
all SENSIT nodes need to be
calibrated the parking lot
must be completely empty.
Note
Individual sensor can also
easily been calibrated via
the Maps.

DIAGNOSE
17.11.1 ICE DETECT MODE
Snowfall or ice-forming will obscure the IR sensor. Based on internal sensors1 and
algorithms, the sensor will set a warning bit in the message data indicating possible
snow or ice deposit. Based on this information, coming simultaneously from multiple
sensors at the same parking lot, a global ice detection algorithm running on the SIS
decides whether to use dual or magnetic detection only and switches the Sensor
Select Mode accordingly. In the figure below an example of the automatic global ice
detection situation of the system is shown.

Sensor select mode
SENSIT Dual Technology sensors feature an infrared sensor and a triple axis
magnetometer. Both technologies work together to provide reliable and accurate
vehicle detection. There are different modes of operation impacting how the status
is calculated. For each individual sensor, the system tracks the actual status of the IR
and magnetic sensor. Based on this information, the “calculated state” of the sensor
(i.e. “free” or “occupied”) is determined. The “Sensor Select Mode” setting
determines how the calculation is made. There are five options for the “Sensor
Select Mode”, see table below.
SSettings
DDescription
Auto Sensor is automatically selected using intelligent
algorithms (Recommended setting).
Magnetic
Only the magnetic sensor is used.
Optical
Only the optical (infrared) sensor is used.
MagneticANDOptical
The
parking bay is occupied when both sensor detect the
vehicle (magnetic + optical).
MagneticOROptical
The parking bay is occupied when at least 1 of the
sensors detect the vehicle.
In auto mode, an algorithm at sensor level monitors the operation and decides which
sensor is most accurate. While the IR sensor is generally leading, the sensor alters
the leading technology in case of incongruity (i.e. when the behavior of both
technologies deviates from what is standard or expected). For example the optical
sensor indicates a continuously occupied bay and the magnetic sensor senses
alternating presence of a vehicle above the SENSIT sensor. After a number of
mismatches (by default 10 consecutive mismatches) between the continuous
occupied optical sensor and the magnetic sensor, the magnetometer will become
leading. As soon as the optical sensor is clean, the sensor will automatically render
IR detection leading.
Calibrate error after .. magnetic events when occupied
The SENSIT Server registers when both sensors of a SENSIT-IR disagree about the
occupancy state. In automatic mode, the optical sensor has a higher priority.
However when the optical sensor is dirty, this will have a negative result on the
accuracy. This setting will generate a Calibration error when the optical sensor
remains occupied while the magnetic sensor registered state changes several times.

19 FREQUENTLY ASKED QUESTIONS
GENERAL
W
What types of SENSIT sensors are available and what is the difference?
There are 3 different types of SENSIT sensors available:
1 SENSIT IR - Magnetic and optical sensor suitable to be built-into the floor of
each parking space.
2 SENSIT Flush Mount - Magnetic sensor suitable to be built-into the floor of
each parking space.
3 SENSIT Surface Mount - Magnetic and optical sensor for mounting onto the
floor of a parking space
What is the accuracy of the SENSIT Flush Mount?
The magnetic sensor can achieve an accuracy of 95%.
What is the accuracy of the SENSIT IR and SENSIT Surface Mount?
The combination of the magnetic and optical sensor has an average accuracy of
above 98%.
How scalable is the SENSIT system?
The SENSIT system is quite scalable. The theoretical maximum number of SENSIT
nodes in one network is about 65000. In general, large installation need to be
divided into smaller sub-networks (segments), which makes it better manageable
and easier to understand. Sites that have more than 500 sensors or more than 15
Relay Nodes need segmentation. Please contact your Nedap account manager.
What is the temperature range for the SENSIT and SENSIT IR?
The temperature range for both SENSIT as well SENSIT IR is -40°C to 85°C [-40 to
185°F]. Temperatures below -30°C [-22°F] might affect accuracy of the magnetic
sensor. The accuracy on the optical sensor remains unchanged.
How does the dual sensor technology principle work ?
The optical sensor is based on IR reflection, using a modulated high power IR LED
transmitter and a sensitive IR diode as receiver. The IR radiation is reflected by the
bottom of a vehicle and captured by the IR diode.
The 3D magnetometer senses the variation in the earth magnetic field when a
vehicle stops above the sensor. The magnetic status of the SENSIT sensor switches
to “occupied” if at least one axis (X, Y or Z) measures a deviation of more than
50mGauss compared to the stored calibration vector.
The IR sensor is potentially more accurate but sensitive to dirt, snow and ice. The
triple axis magnetometer however is not influenced by dirt, snow or ice. By default,
the sensor checks its IR sensor and magnetometer status every second.
Both technologies work together to provide reliable and accurate vehicle detection.
There are different modes of operation impacting how the status is calculated.
For each individual sensor, the system tracks the actual status of the IR and magnetic
sensor. Based on this information, the “calculated state” of the sensor (i.e. “free” or
“occupied”) is determined.
How does the energy efficient Wireless SENSIT Network work?
The medium access protocol is based upon time division multiple access (TDMA).
Time is divided into time slots, which (Relay) nodes can use to transfer data without
having to content for the medium or having to deal with energy wasting collisions of

transmissions. After the frame length, which consists of 16 time slots, the (Relay)
node again has a period of time reserved for it. We have parameterized the duration
of a time slot and the number of time slots. The default timeslot is 100ms and the
number of timeslots in a frame is 16. In the US the system uses also Frequency Hop
Spread Spectrum (FHSS); a pseudo random frequency hopping scheme every
timeslot the SENSIT also changes the frequency. In this way the devices comply with
FCC regulations.
If a SENSIT sensor decides to transmit a messages it asks the first Relay Node within
reach if it is allowed to transmit a message to this Relay Node, if allowed the Relay
Node will receive the message from the SENSIT and retransmits this message to the
next Relay Node or directly to the SENSIT Gateway.
C
Can a SENSIT sensor been used to replace a loop detector?
The SENSIT sensor is designed to detect a changes in either optical or earth
magnetic field. A continuous flow of traffic would generate a constant status change.
Moreover since the system is based on wireless communication, communication is
slower compared to hard wired loop. We therefore do not advise to use the SENSIT
sensor to replace safety loops for critical applications.
MAGNETIC SENSOR
Is the magnetic sensor influenced by snow or ice?
We have tested the system with about 15 cm (5.9 in) of snow during multiple tests.
Snow did not affect the accuracy of the magnetic performance.
Is the magnetic sensor influenced by dirt?
The magnetic sensor is not influenced by dirt like sand, mud or leafs.
How quickly does the magnetic sensor in the node react to a change in status?
Default the magnetic sensor checks its status change every second.
Can the magnetic sensor ‘see’ the magnetic difference between a car and truck?
In a static parking application a SENSIT sensor cannot observe a difference between
a small vehicle and a large truck. The variation in the earth magnetic field changes
under a car or truck does not depend on the height of the vehicle but on where a car
or truck stops. See also the image below to clarify this in more details.
Image 1: Vehicle & earth magnetic field Image 2: Truck & earth magnetic field
How does the SENSIT sensor detect a car and changes the magnetic status from free
into occupied?
The magnetic status of the SENSIT sensor has changed if at any axis (X, Y, and
Z) changes more than 50mGauss compared to the stored calibration vector.
Normally the earth magnetic field vector is about 500mGauss. This can vary
allot from place to place. In order to set the SENSIT sensor to local earth magnetic
field we advise to calibrate the sensors.
Note
Setting or changing the
overdrive filter affects
reaction time.
Note
Default the overdrive filter
is set at 8 seconds.

Asked Question
s
H
How can I avoid a vehicle driving over the SENSIT sensor to trigger a status change
event message?
When a vehicle is driving over a or multiple SENSIT sensors to reach the final parking
bay the overdriven SENSIT sensors will transmit an occupied and free event
message. If the overdrive filter isn’t set. By default the overdrive filter is set to
eliminate these kinds of messages. After setting the overdrive filter the SENSIT
sensor will only transmit a status change event if the SENSIT sensor has been
occupied of free for the set time.
19.2.1 CALIBRATION
Why calibrate?
The local earth magnetic field vector (value and direction) at an installed SENSIT
sensor depends on the orientation of the SENSIT sensor, the amount of metal in the
neighborhood and the location on the earth. When the calibration is done this local
earth magnetic field vector is stored. It is therefore necessary to always calibrate the
sensors.
How can I see if the calibration is done correctly?
When connecting the SENSIT Gateway to the SIS, the SIS software will indicate
calibration errors for sensors which are not calibrated. In the Sensor data message
there is a magnetic un-calibrated bit which warns you if the SENSIT sensor thinks it is
not calibrated well.
Does the parking need to be fully empty to calibrate the SENSIT sensors?
Yes, preferably the parking needs to be fully empty in order to calibrate the SENSIT
sensors. If you need to calibrate a single parking bay it is sufficient if only all
neighboring bays are empty. Easy calibration can be realized through the SIS
website.
My parking lot is hardly ever empty, how can I calibrate the sensors?
If it is not possible to calibrate the entire parking lot, we suggest calibrating the
parking lot section by section directly after installation of the SENSIT’s.
OPTICAL SENSOR
What is the measuring interval of the optical sensor?
The optical sensors periodically checks once per second if there is a status change.
(You can extend battery life by setting slowing measuring intervals.)
Why is the SENSIT IR featured with two detection technologies?
Double detection technology provides a higher accuracy rate. Each detection
technology has its advantages and disadvantages. The combination of both ensures
a reliable detection product in all circumstances and differentiates our product from
any other product in the market. The optical sensor is potentially more accurate but
sensitive for dirt, snow and ice. We specify an average accuracy of 95% for the
SENSIT Flush Mount (only magnet) and 98% for the SENSIT IR (magnet and optical).
In cases of snow or the optical sensor being covered the unit will automatically
switch to earth magnetic field detection.
Which sensor is making the decision; occupied or free?
In most cases the optical sensor is indicating the final status. The algorithm inside
the SENSIT sensor decides which type of sensor to trust. Of course you can ignore
this and decide for yourself which sensor to use, because the state of the magnetic
and the optical sensor is available.

Asked Question
s
W
What is the detection principal of the optical sensor?
The optical sensor is based on IR reflection. We are using a high power IR LED as
transmitter and a sensitive IR diode as receiver. The IR radiation is reflected by the
bottom of a car or truck and is received by the IR receiving diode. This means the
bay is occupied.
Is the optical sensor influenced by snow or ice?
Yes the optical sensor detects based on something covering the sensor. In case the
sensor is covered with snow or frost it will be seen as occupied. In the sensor data
message there is a bit that warns you for possible ice on the SENSIT sensor. As the
SENSIT IR is featured with dual sensing technology you can also decide to switch the
sensors to magnetic detection in winter periods using the SIS software. Beside that
on the SIS there is a global ice detection algorithm implemented which
automatically can decide to switch to the magnetic sensor in case of ice or snow. See
chapter 17.11.1 for more information.
Is the optical sensor influenced by dirt?
The optical sensor is designed to not easily be covered with little amounts of dust or
sand and therefore this will not affect the performance. Larger amounts of dirt will
disable the optical sensor. At an outdoor parking-lot, the self-cleaning surface of the
SENSIT IR ensures that dirt is automatically flushed of and does not easily attach to
the SENSIT IR. This makes it a very usable and practical system. The sites world-wide
installed outdoors have since installation (in about 2006) never been cleaned.
What happens in case of sandstorms, when the optical sensor is covered?
When the optical is covered with sand the sensor cannot detect reflections of a
vehicle that parks over the SENSIT sensor. So the optical sensor will indicate a free
bay, the secondary (magnetic) sensor will detect the movement of the different cars
above the SENSIT sensor. After a few (default: 10) mismatches between the
continuous occupied optical sensor and the magnetic sensor the final status will be
indicated by the magnetic sensor. As soon as the optical sensor is clean, the SENSIT
sensor will automatically switch back to optical detection again.
Is the SENSIT IR affected by direct sun light?
Normally the optical IR sensor is not affected by sunlight. Only at locations close to
the equator when the sun is directly above the SENSIT IR the optical sensor can give
an overexposure alert, which will indicate a free bay.
19.3.1 CALIBRATION
What is the maximum range of the optical sensor?
The IR reflection depends very much on the reflection coefficient of surface it
radiates at. Ceilings of over 3 meters (9 feet) are seen by the optical sensor. You can
set the sensitivity of the optical sensor when applying the sensors for indoor
applications.
Can the optical sensor been used indoors?
The optical sensor can be used indoors, for this the IR transmitting power needs to
be adjusted (calibrated) to avoid the unit from detecting the ceiling.

Is a SENSIT IR snow plough resistant?
When using the SENSIT IR in environments with snowy weather conditions, we
advise to set a tolerance on the snow plough of 2 cm [0.78 in] to ensure the top of
the sensor is not damaged by the snow plough. The SENSIT IR is not fully snow
plough resistant; however it can withstand a few incidental hits. The SENSIT Flush
Mount is snow plough resistant and can be used in areas with frequent snow
conditions, at the cost of a bit lower accuracy.

BATTERY LIFE
What is the battery life?
The battery life of the SENSIT sensor in a good performing network is 5 years this
with default settings of the network and the measurement intervals.
Can batteries be exchanged?
The SENSIT sensors are fully sealed to ensure reliable operation in the outdoor
environment and to avoid any water leakage to the electronics. The batteries cannot
be replaced, as this would create water leakage and unreliable operation. The
SENSIT sensor needs to be replaced after end of battery life. The batteries of the
Relay Node 2G can be replaced, see chapter 10.7.
Can I extend battery life of the SENSIT sensor by adjusting communication settings?
Yes you can extend battery life by adjusting the communication settings. Default the
SENSIT sensors are set to 16 timeslots. This communication setting will realize a
battery life time of 5 years and will achieve a good latency (fast and reliable
communication network). For applications where slower communication (more
latency) is allowed 32 timeslots is recommended to extend battery life time.
Installations using over 15 Relay Nodes should also be set to 32 time slots.
How can I change the communication settings to extend battery life?
Please consult Nedap how to change the communication settings if your application
allows slower communication or if your application needs more than 15 Relay
Nodes.
How do we know if a SENSIT sensor runs out of batteries?
The battery voltages will be requested by the SENSIT Interface Server on a regular
basis. The SIS will display an icon in the node presence list in the SIS if the battery is
low or almost empty. See chapter 17.11.2 and chapter E

you need to swipe the SENSIT sensors with a reset magnet to get them out of stock
mode. In stock/transport mode the SENSIT sensors hardly use any power. In this way
you can have a SENSIT sensor in stock for e.g. a year without influencing the final
battery life.
RELAY NODES
W
What is a Relay Node?
A Relay node consists of a SENSIT configured in an active role and a Relay Node
mounting set. The mounting set allows for easy mounting of the Relay node onto a
lamppost. The Relay node is a normal SENSIT but configured differently, a Relay
Node has a more active role in the wireless network compared to a SENSIT. That is
why we call a Relay Node an active node and a SENSIT a passive node. The
continuous transmitting and receiving of an active node consumes more power than
a passive node who is only listening to a few active nodes to stay synchronized and
to receive incoming messages. The battery life of the Relay Node will be about 2 to
3 years. The advantage is that a Relay Node is still completely wireless and does not
require any power or communication cabling.
What is a Relay Node 2G?
A Relay node 2G is a dedicated product for relaying message from the SENSIT
sensors to the SENSIT Gateway. The Relay Node 2G has an active role and in the
Wireless SENSIT Network. The battery lifetime of the Relay Node 2G is similar as the
lifetime of the SENSIT sensors. The Relay Node 2G is wireless and does not require
any power or communication cabling.
Why are Relay Nodes required?
Relay nodes are required to ensure a faster communication path to the SENSIT
Gateways, a more robust network and less energy consumption. Relay Nodes are
required to ensure that SENSIT sensors positioned in the area can communicate
directly via the Relay Node back to the central system. If each SENSIT sensor would
need to communicate via the other SENSIT sensors installed in the floor, more
communication ‘hops’ are needed. This will cause a slower communicating network,
with a higher chance of missing a message and higher energy consumption.
How much Relay Nodes do I need to install?
The number of Relay Nodes depends on various parameters: number of SENSIT
sensors, distances and obstructions. A minimum of 1 Relay Nodes and 1 SENSIT
Gateway is required per installation to create a 2 path communication possibility for
each SENSIT sensor. Nedap can provide you with more detailed information on the
amount of Relay Nodes per installation for your site.
Has Nedap a tool to determine the number of needed Relay Nodes?
There is a tool available to make a better estimation of needed equipment, see
chapter 4. Please ask your Nedap account manager for more information.
Note
Use of Relay nodes is
mandatory to ensure a fast
communicating, more
stable and a less energy
consuming SENSIT network.

How do I replace a Relay Node?
After end of battery life, the SENSIT can easily be taken out of the Relay Node
mounting set. Only the SENSIT sensor configured as Relay Node would need to be
replaced. The batteries of a Relay Node 2G can be replaced, see chapter 10.7.
Can the Relay Nodes also be used for indoor car parks?
Yes, the Relay Nodes can also be used for indoor car parks, see also picture below.
Indoor car parks might require more Relay Nodes due to mounting height
restrictions and influence of concrete on communication.
SENSIT GATEWAY
What is the SENSIT Gateway?
The SENSIT Gateway is the central unit which collects the events from SENSIT
sensors via the Relay nodes and transmits this information to the host system or
SENSIT Interface Software.
What is a Data Collector?
The Data Collector is the previous name for the SENSIT Gateway.
Can I implement data from the SENSIT Gateway directly?
No, this feature is not supported and subject to change. For easy integration we
advise to use the SENSIT Interface Software.
What is the most critical part of the SENSIT system?
The most critical part is the SENSIT Gateway when the power of the SENSIT Gateway
is interrupted or if the SENSIT Gateway is damaged the whole Wireless SENSIT
Network will stop working. Only with a good and powered SENSIT Gateway the
wireless network will start. By using an UPS, (short) power failure can be solved.

W
Where do I mount the SENSIT Gateway?
The SENSIT Gateway can be installed within 25 m [84 ft] from the first SENSIT node
or Relay Node. Be sure not to position the SENSIT Gateway in a metal enclosure as it
will block the RF communication. The SENSIT Gateway can be mounted in a plastic
housing, which is transparent for RF signals.
What power wiring (cable specs) do I need for the standard Data Collector?
Power: 100-240 VAC, 50-60 Hz, 180mA,
Power input: 5 VDC, max 1A
Power consumption: 5VA
Communication between Data Collector and SIS: Ethernet Cat 5 E
Can the Data Collector GPRS be powered by a solar panel?
There are already several customers who autonomously power
the Data Collector GPRS with a solar panel. Also the Data
Collector GPRS at the Nedap test-site is powered by a solar panel
(since December 2011).
The autonomous solar panel system at the Nedap test-site is a
30Wp Solar panel, a charge regulator and two 22Ah /12V battery
in parallel. See picture at the right
The Data Collector will not consume more than 60mA at 12VDC on average.
Can the SENSIT Gateway be powered by a solar panel?
The SENSIT Gateway can also be powered by a Solar panel and it will not consume
more than 120mA at 12VDC on average.
How much data will a the SENSIT Gateway use?
Normally the data usage will be below 250MB per month.
Can I replace the antenna for one that I can mount on top of a metal box and keep
the SENSIT Gateway inside this metal cabinet?
As for operational purposes this should not be an issue, on the condition that a
suitable antenna is applied. However ETSI and FCC does not allow change of the
antenna, and therefore as a manufacturer we cannot approve antenna change for
this reason.
How often does the SENSIT sensor send an event to the SENSIT Gateway to alert a
status change?
The SENSIT sensor sends an event message immediately after a status change.
The baud-rate of the Data Collector is 115200 can I change it into another value?
The baud-rate of the Data Collector is fixed, you cannot change it.
Can I built the SENSIT Gateway into a pay & display machine?
Yes, when the pay & display machine is featured with Ethernet communication, this
communication could be applied. Keep into consideration that the RF antenna of the
Gateway should be positioned behind RF transparent material (such as plastic) and
not incorporated in metal.

SENSIT INTERFACE SOFTWARE (SIS)
W
What is the SIS?
The SIS (SENSIT Interface Software) allows for easy configuration and filtering of
event messages received by the SENSIT Gateway. The SIS enables configuration,
installation, basic administration and integration of the SENSIT system SIS
functionality includes;
x Easy integration via SOAP or REST
x Easy remote support via web interface
x DNNP (Dynamic Node Numbering Protocol)
x Connection of multiple SENSIT Gateways
x Filtering of events
x Easy event configuration
x Easy management of the entire Wireless SENSIT Network
x Automatic calibration
x Debug and analyze tool
x Automatic collection of missing messages
x Configuration of parking bays
x Stand-alone system with control of display per zone.
x Graphics to indicate parking spaces and overstay
Why use a SIS?
Configuration and integration of the data from the SENSIT system becomes much
easier. The site can be accessed remotely allowing Nedap to give you better support
on the installation.
Can I control a display with the SIS?
Yes using a wireless display node built-into a display, the display can become part of
the Wireless SENSIT Network (WSN). You can set in the SIS software which parking
zone the display should control and indicate. See chapter 17.8.7 for more
information. Using this option a simple standalone application could be created with
displays indicating available spaces. No more than 2 wireless displays are allowed in
the WSN to make sure the display messages aren’t influencing the WSN too much.

Asked Question
s
NETWORK & COMMUNICATION
H
How much events can a SENSIT node store?
Every SENSIT node is capable of storing 32 events in its internal memory.
What causes the latency of a SENSIT sensor?
The latency is built up out of different aspects;
x
The measurement interval;
The interval the SENSIT sensor verifies it status changed, default set at 1
second.
x
The overdrive filter;
The overdrive delay set in the SENSIT sensor is by default set at 8 seconds.
x
The number of hops;
The number of hops a message needs to arrive at the SENSIT Gateway,
every hop takes about 2 seconds.
x
Passive collisions;
In a busy car park multiple SENSIT sensors want to transmit their status
change message simultaneous, which might create passive collisions. In
order to reduce this we advise to ensure that each SENSIT sensor can at
least communicate with 2 Relay Nodes offering multiple communication
paths.
Example with default settings and without passive collisions:
The magnetic and optical sensor measures every second if the status of the
bay is changed. The overdrive filter waits 8 seconds before it transmits the
event. In this example the event is transmitted via 2 Relay Nodes; first from
the SENSIT to the nearest Relay Node and then from this Relay Node to the
Relay Node close to the SENSIT Gateway and finally from this Relay Node to
the SENSIT Gateway. The total (worst-case) time needed is:
Measurement + overdrive + SENSITÆRN + RNÆRN + RNÆ SENSIT Gateway
= 1+8+2+2+2 = 15s
Example with default settings and with one passive collision:
The magnetic and optical sensor measures every second if the status of the
bay is changed. The overdrive filter waits 8 seconds before it transmits the
event. In this example the event is transmitted via 2 Relay Nodes; the
sequence of transmitting the messages is the same as in the example above
but now a collision occurred in the first transmission; another SENSIT
transmitted an event at the same time to the Relay Nodes. The total (worst-
case) time needed is now:
Measurement + overdrive + collision + SENSITÆRN + RNÆRN + RNÆ
SENSIT Gateway = 1+8+10+2+2+2 = 25s
How many seconds does an event message take in general?
The transfer time is depending on the number of hops and if passive collisions take
place. A collision free transfer via one Relay Node takes less than 5 seconds, for
every extra hop add 2 seconds. For a busy parking lot take into account at least 10
seconds extra for possible passive collisions.
Is the package number always increasing per SENSIT?
Yes, the package number is automatically increased in sequence number per SENSIT
and the message is unique based on a combination of SENSIT ID number and
package number.
