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.
