Sensor, type PIR, is designed for motion detection, is used to detect human presence in indoors in alarm and lighting systems. The sensor is powered with the voltage in the range from 4.5 V to 20 V, has a range of up to 7 meters. Object detection is indicated by a high status.


The digital output allows connection of the sensor to any board equipped with a microcontroller, e.g. Arduino, STM32Discovery or minicomputer Raspberry Pi. Pins are goldpin connectors (pitch of 2.45 mm) for connecting the sensor by wires.


The product is compatible with Arduino

Method of application

Power supply (4.5 V to 20 V) must be connected to external pins marked, respectively, by the symbol VIN and GND in the picture below. Detection of an object in the field of view of the sensor, is signaled with a high status that appears at the OUT output.

Thanks to potentiometer, the user can adjust:

  • T1 - duration of the high state upon detection of the object
  • T2 - sensor sensitivity (distance, which detects the movement of an object)


With the jumper, which has to be self-soldered, mode of operation is selected from two available outputs:

  • retriggering (jumper in H position) - the output reaches a high status, after the detection of the object and it is held for the entire time of detection of continued motion, the sensor, by default, is in this mode (no jumper)
  • non-retriggering (jumper in position L) - the output reaches a high status only once, after detection of the object and then goes to a low status, regardless of whether the movement continues


  • Supply voltage of  DC: 4.5 V to 20 V
  • Power consumption in standby mode: 50 uA
  • Measuring range: max. 7 m
  • Viewing angle: up to 100 °
  • Digital output:
    • High status - object detected
    • Low status - no object
  • The dimensions of the base of module: 32,5 x 24,5 mm
  • Bowl diameter: 23 mm
  • Bowl height: 18 mm
  • Total height: 30 mm (with elements mounted in the bottom of the board)


  • Voltage to 4.5 V
  • Voltage from 20.0 V
  • Sensor - type PIR
  • Sensor - assembly for case
