Functional description
PCR1 is a radar-based people flow sensor with LoRaWAN data connection.
The integrated radar sensor detects persons moving in parallel to the housing surface.
A person is counted as soon as he or she enters and leaves the detection zone. The unit can be
installed horizontally at a height between 125 and 140 cm or upside down at a ceiling. The maximum
measuring distance (distance between sensor and person) is 10m.
The number of persons counted is transmitted cyclically via a LoRaWAN connection.
Device start (LED flashes slowly)
After applying the operating voltage, the device is logged on to the LoRaWAN network. During this
phase the LED flashes slowly. After successful registration the LED goes off.
Operation (LED off)
In normal operation, all persons entering and leaving the sensitive area of the radar are counted. This
is indicated by a short lightening of the LED. The movement of the persons must be carried out
parallel to the surface of the device. Fast movements, e. g. of hands or objects, are ignored to avoid
miscounting.
Error state (LED flashes quickly)
The device changes to error status in following conditions:
•The LoRaWAN configuration is incomplete
•Access to the LoRaWAN network is denied.
•There is no LoRaWAN available in the area or signal is weak.
You can use our free PCR1 Setup Tool to find out more about the current error.
The device tries to reconnect after one minute in error state.

Installation
The person counter can be mounted either laterally or overhead. The maximum
Detection distance is approx. 10 m. The best results are achieved if the housing surface is parallel to
the walking direction.
Important! This device is based on the principle of approximation and distance from the
Doppler-Radar sensor. People are counted from every direction.
Optimum placement / detection range
The device is equipped with a highly sensitive Doppler radar sensor. Movements at an angle of +/- 40°
horizontal and +/- 17° vertical are detected up to a distance of 10m.
For optimal function please note:
•A person is counted as soon as both areas are crossed. However, it does not matter in which
order this is done.
•Both areas should be the same size and should not be covered by objects or walls.
•Avoid moving objects like escalators or revolving doors in sensor range

Wall mounting
For side mounting, e. g. on a door frame, the following must be observed:
•The person counter should be mounted at a height of 125... 140 cm from the floor. We
recommend 135 cm.
•The device should be mounted upright for the maximum detection range
•The front side of the device should be parallel to the walking direction.
Ceiling mounting
The person counter can be mounted on a ceiling to count people passing underneath the device.
Please note the following:
•The distance between the unit and the persons passing through below should be more than
50cm.
•The device should be mounted crosswise to the walking direction.
Electrical connection
The device is supplied with a 5V power supply unit with micro-USB connection.
Open the cover on the back of the housing and insert the micro-USB plug into the
corresponding socket.

LoRaWAN Credentials Configuration
The following example shows a typical "Over-the-Air-Activation" configuration of the device.
1. Connect PCR1 with a USB cable to your PC.
A virtual COM-Port driver should be installed automatically by Windows.
2. Start PCR1 Setup Tool select COM-Port and press ‘Connect’ (1).
After a moment you should see device information from the connected PCR1 (2).

3. Enter your LoRaWAN Credentials and press ‘Set’.
All Data is stored in the Device. Network registration will start immediately.
LED will go off if connection is successful.
Important!
Make sure the device is registered with your LoRaWAN network provider prior to
this step.
4. You can set the transmit interval in a range between 1 … 240 minutes.
People count will be zeroed after transmitting.

Monitoring
Use PCR1 Setup Tool for debugging your LoRaWAN connection and checking device functions.
1. Actual Peorpleflow counter that will be transferred with next transmit.
2. Time until next transmit. By pressing ‘TX Now!’LoRa uplink will be enforced immediately.
You may change the TX interval settings under tab ‘Device Settings’.
