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.

2.5 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 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; 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 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 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

24/92
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.

13 SENSIT INTERFACE SOFTWARE
13.1 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
13.2 USERS
Start the web browser and enter the SENSIT Server hostname. A login screen will appear.
Please view the document outlining the Data Collector configuration settings for the details

summarizes and displays the actual status of a specific parking zone.
Figure 35: Parking enforcement dashboard screen
Different enforcement information of all parking zones are displayed: Permits in use,
Occupied permit bays, Occupied bays, Bays in overstay and the Permit violations.
The Electronic Parking License (EPL) is a hardware device that is physically placed inside a
vehicle or it is an App that is running on a smartphone. Whenever the 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.
Note
Configuration is only available
under sensitadv login.

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.
13.6.7 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.
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.

Frequently Asked Questions
75/92
15 FREQUENTLY ASKED QUESTIONS
15.1 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 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 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 sensor to replace safety loops for
critical applications.

Frequently Asked Questions
76/92
15.2 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.
15.2.1 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 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.
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
77/92
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.
15.3 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 13.9.1 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.
SENSIT SYSTEM | MANUAL
Frequently Asked Questions
78/92
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.
15.3.1 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.
15.4 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 (eg.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.

15.6 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 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 7.7.
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 13.9.2 and chapter 13.9.3 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 you can have a
SENSIT sensor in stock for e.g. a year without influencing the final battery life.
Note
A network uptime below 99%
will reduce the battery life
significantly.

15.7 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 tool available to make a better estimation of needed equipment, see chapter 4.
Please ask your Nedap account manager for more information.
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)

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 7.7.
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.
15.8 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 SIS: Ethernet Cat 5 E

Frequently Asked Questions
82/92
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.

15.9 SENSIT INTERFACE SOFTWARE (SIS)
What is the SIS?
The SIS (SENSIT Interface Software) allows for easy configuration and filtering of 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 13.6.7 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.

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 13.8.5.

Frequently Asked Questions
85/92
15.10 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'.
