Vehicle Detection Sensor for Vehicle Counting
●The sensor can count moving vehicles by using
dual detection technologies : Doppler shift and
FMCW (Frequency-modulated continuous-wave).
●Detection of objects other than a vehicle can be
reduced (patent pending).
●Built-in heater reduces snow on the sensor
(automatically activates based on the outside air
temperature).
●Not affected by underground obstructions, this
product is installed above ground.
●Reduced installation time as access road for
vehicle is not closed, as no civil engineering
works is required.

●Detection Principle
●This sensor uses reflection of a microwave signal to detect a vehicle.
(The higher the reflection, the easier the detection becomes.)
●The microwave sensor uses FMCW technology, it can detect a vehicle in the lot.
●The detection logic is shown below.
3-1 Detection Principle and Basic Operation of the Sensor
Microwave Sensor
Detection Area
If only a person enters into the detection area, the
relay signal output will not trigger (It may detect,
however if a crowd of pedestrian or a person with
luggage).
When a vehicle is present, the sensor detects the vehicle.
Before Using the Product
3
When the vehicle leaves the detection area, the sensor will
change to a non-detection status.
If a vehicle is parked in the detection area, the sensor
will maintain the detection status.
NOTE
The following cases may occur due to the sensor detection principles.
●If a pedestrian or an object is in the detection area after the Vehicle leaves, the sensor
will maintain the detection status even if the vehicle leaves the detection area.
The sensor may not revert back to a non-detection status if a flag/banner, tall weeds,
and/or snow remain.
●If one vehicle tailgates another vehicle very closely when entering the detection area,
they may be recognized as one vehicle.
-5-
Install the pole for the sensor in the following layout configuration. The sensor will not work correctly unless its
installation direction and height are correct.
Installation height: 500mm(19.69in.) from the ground to the bottom of the sensor
Installation angle: 90 degrees to the vehicle direction of travel.
●Always install the sensor on the vertical pole that is mounted in or on the ground.
Installing a sensor on a tilted pole will result in a detection of the ground by the sensor
and correct operation is not ensured.

●Two way traffic lane : To use the sensor for a two-way traffic road, adjust the sensing
distance so that the detection area should not cover the opposite lane (see P.13 "4-2.
Setting Verification and Modification").
Vehicle Path
Two way traffic lane : Install the sensor on the the lane of traffic you wish to monitor.
The sensor cannot detect a vehicle in the opposite lane.

●Do not install any moving object such as flags or banners in the sensor's detection
area. Remove any vegetation from the detection area, or reconfigure the detection
area to be smaller. Not following these steps may stop the sensor reverting back to
non-detection status or delay the change of status.
●Do not use a fluorescent lamp around the detection area. It may prevent proper
operation of the sensor.
NOTE ●If the pole is installed on a slope, install the sensor higher or lower in order to adjust
the height of the set detection range to 500mm(19.69in.) from the ground. It may
reduce the detection capability compared to the normal installation.

The following cases may occur due to the sensor's characteristics.
●The sensor may not work properly if it is installed in a location that does not meet the
installation conditions.
●The sensor may not work correctly if it is not installed as per the instructions in this
manual.
●Pedestrians, bicycles, or any large object entering the detection area may be
detected.
●Detection may fail or be intermittent depending on a vehicle size.
●Depending on the position and/or direction of vehicle approach, the distance to be
detected may become shorter or may not be detected.
●Performance of the sensor may be affected if :
●The sensor pole is not vertical from the ground
●The sensor surface is covered with ice, snow, or dirt.
●Heavy snowing conditions
3-3 Sensor Detection Recommendations
●A vehicle is detected when it approaches the sensor at speeds of 2 to 60kph (1.24 to 37.28mph).

[5] Detection Area Check: Go to P.15
Verify the detection area. If needed, change the installation angle of the unit and/or sensing distance
setting.
* Once the installation condition such as the angle is modified, perform the calibration again.
[6] System Operation Check: Go to P.16
Check the whole system operation that is connected to the sensor.
[7] Detailed Setting adjustment (if needed): Go to P.18
Change the parameter of settings if necessary after the
system operation check.
[8] Attaching Front Cover: Go to P.12
Attach the front cover, and the installation is complete.
●Do not use chemicals such as alcohol.
●Do not apply high-pressure water. It may result in a failure or fire.
Maintenance Cleaning
If the unit becomes dirty, lightly wipe sensor with a soft brush or cloth.
If not cleaned yet, use a neutral detergent to clean the sensor.
