PCR2-IN Quickstart Guide

PCR2-IN

Installation

Mounting location thoughts

PCR2 are 1D sensors measuring people's movement from two directions along a virtual line. As it cannot look through people, finding the right place is essential to get good results:

  • Narrow passageways are preferable, as people have to walk one behind the other
  • No objects in the beam except the people. Walls and objects can deflect the radar beam and lead to reflections.
  • Distance from device surface to moving objects should be over 30cm

Overhead mounting

PCR2-IN

Mount the sensor in a corridor above the direction of walking.

Important: LEDs need to be in line with the moving direction.

Minimal Settings

  • Set MinDist to the distance between people's heads and the device.
  • Set MaxDist to the room height (distance between PCR2 and the floor).
  • Set BeamAngle to 40° for tight conditions (Beam Angle Range is 30-80°). Vertical angle is 34° fixed and cannot be changed.
  • Lower Sensitivity if the device counts too much.
  • Increase Sensitivity if device counts too less.

Overhead mounting

PCR2-IN

Mount the sensor sidewise at a height of 1.2-1.4m above floor.

Minimal Settings

  • Set MinDist to the distance between device and the arms of passing by persons
  • Set MaxDist to the passage wodth
  • Set BeamAngle to 40° for tight conditions (Beam Angle Range is 30-80°). Vertical angle is 34° fixed and cannot be changed.
  • Lower Sensitivity if the device counts too much.
  • Increase Sensitivity if device counts too less.

Electrical Installation

The device can by powered using an external USB power adapter or an external 5-12V DC power source.

PCR2-IN There are 2 cage clamp terminals in the device to connect the power supply wires * Use 12-22AWG (0.2 – 0.75mm2) * Pay attention to the polarization * Take a screwdriver and press LIGHTLY on the clamps to be able to insert the wire

Initial Setup

The devices must be registered once in a LoRaWAN network.

Open enclosure

Remove the four screws from the casing to gain access to the device. PCR2-IN

Connect to CONFIG port

Use a USB to Micro USB cable to connect the PC to your device. PCR2-IN

Start PPX

Start Parametric Product Explorer to connect to your device. PCR2-IN{ }

LoRaWAN Settings

PCR2 includes a LoRaWAN V1.0.3 Reg A modem. In order to register the device to a LoRaWAN you need to read out the LoRaWAN keys.

Open section LoRaWAN Settings. Use the following values to register the device to your LoRaWAN.

  • DevEUI
  • AppEUI
  • AppKey

Additional settings:

  • Enable/Disable Confirmed Uplinks
  • Choose a Frequency Subbands (Important for US915 or AU915 devices)
  • LinkCheck Interval can test the connection on regular intervals and rejoins in case of connection loss

Signalisation

PCR2-IN uses 2 LED for movement and status signalisation PCR2-IN

  • Left LED blinks slowly: Device starts
  • Left LED blinks fast: Device initialization error
  • Left LED pulses once: Person detected from right to left (RTL)
  • Left LED blinks 3 times: Person detected, but poor signal quality
  • Right LED pulses once: Person detected from left to right (LTR)
  • Right LED blinks 3 times: Person detected, but poor signal quality
  • Both LEDs blinking slowly: Joining LoRaWAN
  • Both LEDs blinking fast: Join or uplink failed
