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.

2.1 ARCHITECTURE
The actual status (occupancy) of the SENSIT sensors is finally collected by one or
more Data Collector. The SENSIT sensors transmit their status via one or more Relay
Nodes to the Data Collector. The Data Collector is the interface between the wireless
sensors network and the SENSIT Interface Software running on the server. The Data
Collector transmits status information about the sensors to the server using TCP/IP
via Ethernet or GPRS communication.

2.5 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.

2.6 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:
Installation
Configuration
Basic administration
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 Data
Collectors. 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 to SOAP or REST 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 SIM 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; Data Collectors 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.
4.1 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 Data Collector. 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 tool you
can determine the needed
components, but it will
always be an estimation.

4.3.3 PLACE THE DATA COLLECTOR
Place at least one Data Collector for every 250 bays. Use the information you
already gathered or ask the client for the installation options for the Data
Collector(s). At least you need a power connection and for a standard Data Collector
you also need an internet connection.
Figure 8: RelayNodeTool: DataCollector placement.
4.3.4 PLACE THE RELAY NODE
Place the Relay Nodes at locations were you can mount it e.g. at lampposts in a way
that it covers all parking bays. With the tool you can choose between Relay Nodes
2G (omni- or directional) or Relay Nodes 1G.

4.4.2 SET THE SCALE
Also Set the scale, this location is a parking basement with a roof, large concrete
columns and walls. This will influence the range of the Relay Nodes and therefore
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 DATA COLLECTOR
Because this basement parking area is half open we can use the Data Collector of
the open area, so we don’t need to add one for this segment.
SENSIT SYSTEM | MANUAL
RelayNodeTool
24/93
4.4.4 PLACE THE RELAY NODE
Place the Relay Nodes at locations were you can mount it e.g. at lampposts in a way
that it covers all parking bays. With the tool you can choose between Relay Nodes
2G (omni- or directional) or Relay Nodes 1G.
There are 2 large concrete walls and after every 3 parking bays there is large
concrete pillar, all is indicated with red. This will influence the range and radiation
pattern of the Relay Nodes.
Figure 13: Imported map with concrete wall and pillar indication.
Probably with only 3 Relay Nodes 2G it is possible to get coverage of all bays, but
because of these large influencing concrete objects we used 2 Relay Nodes 2G extra
to make sure all SENSIT sensors are sufficient reachable.

8.6 INSTALLATION PROCEDURE
Below the mounting procedure for the SENSIT sensor.
SENSIT sensor mounting procedure
Step 1:
Preparation
Indicate on the closed parking lot where the
SENSIT sensor should be mounted. Distribute
the SENSIT sensors over the parking lot and
write down the correct ID numbers on your
installation plan.
Step 2:
Drilling
Drill a hole of Ø 85 mm [3.35 in] and at least
55 mm [2.16 in] deep into the centre of the
parking bay
Step 3:
Gluing
Apply the right amount of filler and pour into
the hole.
Step 4:
Mounting
Double-check the node ID number and the
parking bay on the installation plan and
place the SENSIT sensor into the hole.
Step 5:
Cleaning-up
After mounting the SENSIT sensors in all
parking bays or a selection of parking bays.
Clean up the parking bays and remove all
(metal) tools and objects.
Step 6:
Activating
All SENSIT sensors are set into
transport/stock mode during shipment. After
installation all mounted SENSIT sensors must
be swept with the reset magnet.
Step 7:
Calibrating
After installation the SENSIT sensor must be
calibrated. Ensure that the parking space is
empty and that there is no car parked on top
of the sensor or on neighboring parking bays.
SENSIT sensors can be calibrated via the
SENIST Interface Software (SIS). See chapter
12.5.6 for more information about
calibration.
Step 8:
Glue curing
Leave the filler harden for 8 hours before
vehicles are allowed in the parking space
again.
8.7 REPLACEMENT
When the battery life of the SENSIT IR fails after specified life time, we advise to
replace the unit completely. The SENSIT IR is fully sealed and for outdoor use
therefore batteries cannot be replaced.
Drill out the old SENSIT IR and complete the mounting procedure as describe in the
previous paragraph.
Ensure to note the node ID number of the SENSIT IR to the parking bay. Update the
parking bay configuration list in the SIS software to ensure the new sensor is linked
to the right parking bay.
Note
Take attention that you
fixate the SENSIT sensor
during the curing time
otherwise the sensor will
start to float.
Note
Once out of the
transport/stock mode the
battery lifetime starts to
count.
Note
When the SENSIT sensors
are not calibrated they
hardly send any messages.
This is due to the fact that
there are no events
generated because the
magnetic thresholds are not
crossed.

10.5 INSTALLATION PROCESS
Follow the recommended installation procedure for the SENSIT Surface Mount as
described below.
SENSIT Surface Mount mounting procedure
Step 1:
Preparation
Indicate on the closed parking lot where the
SENSIT sensor should be mounted. Clean
the location where the sensor should be
mounted. Distribute the SENSIT sensors
over the parking lot and write down the
correct ID numbers on your installation plan.
Step 2:
Gluing
Pour the filler into the mounting ring of the
SENSIT Surface Mount. A pneumatic kit
dispenser makes it easy to apply the glue
into the mounting ring. For good fixture with
the surface please fill the entire mounting
ring.
Step 3:
Mounting
Press firmly and double check the ID
number.
Step 4:
Cleaning-up
After mounting the SENSIT sensors in all
parking bays or a selection of parking bays.
Clean up the parking bays and remove all
(metal) tools and objects.
Step 5:
Activating
All SENSIT sensors are set into
transport/stock mode during shipment.
After installation all mounted SENSIT
sensors must be swept with the reset
magnet.
Step 6:
Calibrating
After installation the SENSIT sensor must be
calibrated. Ensure that the parking space is
empty and that there is no car parked on top
of the sensor or on neighboring parking
bays.
SENSIT sensors can be calibrated via the
SENIST Interface Software (SIS). See chapter
12.5.6 for more information about
calibration.
Step 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
with a few dots of glue.
Note
Once out of the
transport/stock mode the
battery lifetime starts to
count.
Note
When the SENSIT sensors
are not calibrated they
hardly send any messages.
This is due to the fact that
there are no events
generated because the
magnetic thresholds are not
crossed.
SENSIT SYSTEM | MANUAL

All SENSIT sensors are set into
transport/stock mode during shipment.
After installation all mounted SENSIT
sensors must be swept with the reset
magnet.
Step 4:
Calibrating
After installation the SENSIT sensor must be
calibrated. Ensure that the parking space is
empty and that there is no car parked on top
of the sensor or on neighboring parking
bays.
SENSIT sensors can be calibrated via the
SENIST Interface Software (SIS). See chapter
12.5.6 for more information about
calibration.
Step 5:
Update SIS
Ensure to note the node ID number of the
SENSIT Surface Mount to the parking bay
and update the parking bay configuration
list in the SENSIT Interface Software (SIS),
see chapter 12.5.2
Note
Once out of the
transport/stock mode the
battery lifetime starts to
count.
Note
Also ensure not metal parts
(such as tools) aren’t
positioned in the
surrounding of the sensors
as this might affect
calibration.
Note
When the SENSIT sensors
are not calibrated they
hardly send any messages.
This is due to the fact that
there are no events
generated because the
magnetic thresholds are not
crossed.

12 SENSIT INTERFACE SOFTWARE
12.1 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 Data
Collectors. 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

The SENSIT Server will ask the node if all state events are received. The last state
event message is transmitted again to the SENSIT Server to verify the overstay.
Overstay verify attempts
This menu option will set the number of times the SENSIT Server tries to receive the
last state event message. Max. 5 can be selected. If the overstay verify attempts fail
an unverified overstay event is generated.
12.5.6 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.
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.
SENSIT SYSTEM | MANUAL
SENSIT Interface Software
59/93
Figure 44: 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.
SENSIT SYSTEM | MANUAL
SENSIT Interface Software
60/93
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.
12.5.7 EPL MODULE
The Electronic Parking License (EPL) is a device that is physically placed inside a
vehicle. Whenever the vehicle for a specific period of time stops moving, the EPL
considers the vehicle to be parked. In that case, the EPL 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.
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.
How to get an overview of occupied parking bays that require an EPL license is
described in chapter 12.7.4.
How to setup parking bays that require an EPL license is described in the chapter
Parking Bay Groups.
How to register EPL licenses into the system is described in the chapter: License /
User Management.

This screen indicates the SENSIT nodes that do not transmit any state event
messages. For example, an event is created when a vehicle enters the parking bay
and a difference in the magnetic field is has been detected. When the difference in
the magnetic field does not result in a state change event, in other words no change
in the occupancy, this might indicate that the SENSIT has not properly been
calibrated. The screen indicates the number of events received from a specific
SENSIT without a state change.

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

14 FREQUENTLY ASKED QUESTIONS
14.1 GENERAL
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 can more easily
be divided into smaller sub-networks, which makes it better manageable and easier
to understand.
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 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 Data Collector.
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
SENSIT SYSTEM | MANUAL
Frequently Asked Questions

sensor to replace safety loops for critical applications.
14.2 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.
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.
14.2.1 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?
Note
Setting or changing the
overdrive filter affects
reaction time.
Note
Default the overdrive filter
is set at 8 seconds.
SENSIT SYSTEM | MANUAL
Frequently Asked Questions
78/93
When connecting the Data Collector 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.
14.3 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.
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 12.8.1 for more information.
SENSIT SYSTEM | MANUAL
Frequently Asked Questions
79/93
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.
14.3.1 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.
14.4 MORE INFORMATION SENSIT AND MOUNTING
What filling material should I use?
The best way to fix the SENSIT sensors into the floor of the parking space is using
rapid mortar TM 5R. Ensure to fixate the SENSIT sensors during curing time, to avoid
them from floating in the mortar. When you want to use another brand of rapid
mortal please sent us the datasheet so we can analyze this and advise you on use.
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.

14.6 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 sensor is 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.
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 Module on a regular
basis. The SIS will display an icon in the node presence list in the SIM if the battery is
low or almost empty. See chapter 12.8.2 and chapter 12.8.3 for more information.
If I keep the product in stock for some time, do the batteries run down?
When shipped the units are in stock/transport mode to save battery life. That is why
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
Note

you can have a SENSIT sensor in stock for e.g. a year without influencing the final
battery life.
14.7 RELAY NODES
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 Data Collector. 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 Data
Collectors, 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 Data
Collector 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 beta tool available to make a better estimation of needed equipment.
Please ask your Nedap account manager.
What is the communication distance between Relay Nodes and other components of
the system?
Below the maximum recommended distances between the different nodes.
Data Collector Relay Node 25 m (82 ft)
Relay Node Relay Node 50 m (164 ft)
SENSIT Relay Node 25 m (82 ft)
Data Collector SENSIT 25 m (82 ft)
Data Collector Relay Node 2G omni-directional 35 m (135

Note
Use of Relay nodes is
mandatory to ensure a fast

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.
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.
14.8 DATA COLLECTOR
What is the Data Collector?
The Data Collect 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.
Can I implement data from the Data Collector 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 Data Collector when the power of the Data Collector is
interrupted or if the Data Collector is damaged the whole Wireless SENSIT Network
will stop working. Only with a good and powered Data Collector the wireless
network will start. By using an UPS, (short) power failure can be solved.
Where do I mount the Data Collector?
The Data Collector can be installed within 25 m [84 ft] from the first SENSIT node or
Relay Node. Be sure not to position the Data Collector in a metal enclosure as it will
block the RF communication. The Data Collector can be mounted in a plastic
housing, which is transparent for RF signals.
How can we make the Data Collector useable outdoors?
The standard Data collector can be placed in a plastic housing suitable for outdoor
use. An outdoor box which is made of a conduction material or contains a lot of
conduction material can create some problems as it blocks RF communication. A
better solution is to use the Data Collector GPRS it has IP65 housing.

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 SIM: 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 GPRS will not consume more than 60mA at 12VDC on average.
How much data will a Data Collector GPRS 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 Data Collector 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 Data Collector 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 Data Collector 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
Data Collector should be positioned behind RF transparent material (such as plastic)
and not incorporated in metal.

14.9 SENSIT INTERFACE SOFTWARE (SIS)
What is the SIS?

event messages received by the Data Collectors. The SIS enables configuration,
installation, basic administration and integration of the SENSIT system SIS
functionality includes;
Easy integration via SOAP or REST
Easy remote support via web interface
DNNP (Dynamic Node Numbering Protocol)
Connection of multiple Data Collectors
Filtering of events
Easy event configuration
Easy management of the entire Wireless SENSIT Network
Automatic calibration
Debug and analyze tool
Automatic collection of missing messages
Configuration of parking bays
Stand-alone system with control of display per zone.
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 12.5.8 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 to much.

How does the overstay sequence work?
The accuracy of detection is of critical importance when using the information for
enforcement applications. You want to avoid issuing unjustified tickets. In the table

How do we know when a SENSIT or Relay Node is working well?
With the node cross check menu on the SIS you can detect if all SENSIT sensors are
still communicating. Logged in as an advanced user it is possible to get a graphical
overview of the performance of the wireless SENSIT network. For more information
see chapter 12.7.5.

Frequently Asked Questions

14.10 NETWORK & COMMUNICATION
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;
The measurement interval;
The interval the SENSIT sensor verifies it status changed, default set at 1
second.
The overdrive filter;
The overdrive delay set in the SENSIT sensor is by default set at 8 seconds.
The number of hops;
The number of hops a message needs to arrive at the Data Collector, every
hop takes about 2 seconds.
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 Data Collector and finally from this Relay Node to
the Data Collector. The total (worst-case) time needed is:
Measurement + overdrive + SENSITRN + RNRN + RNData Collector =
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 + SENSITRN + RNRN + RNData
Collector = 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.

How do we map the double words corresponding to "Sent time" and "event time" to
real dates?
The double word is the time in seconds from January 1st 1970 this is also used
within UNIX and therefore also known as 'Unix-time'.
