Manufacturer: OpenPlatform


Sensor, type PIR, is designed for motion detection, is used to detect human presence in indoors in alarm and lightingsystems. 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,STM32Discoveryor minicomputer Raspberry Pi. Pins aregoldpin 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
  • Output voltage: 3,3 V
  • 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)

PIR HC-SR501 motion detector - green


Average grade


Customers opinion
The sensor is like a sensor - it sees what it is supposed to see and returns what it is supposed to return. No reservations
I recommend. Reacts quickly to movement.
It's ok, it works very well, quite sensitive
Solidly made. It works
Good sensor (long range and sensitivity) with low power consumption, sensitivity can be adjusted. Perfect for home alarm systems.
Everything as ordered. I RECOMMEND !!!
It works. The product description is correct.
it works cool
Perfect for the implementation of various projects with children. Workmanship very much. Good.
Works cool.

B. good product.
It works ok. Note that the signal output gives 3V3 voltage and there is no current efficiency (FETa will not reload properly without driver).
As for me, for amateur use at home, OK. However, if someone wanted to make some reliable alarm systems on it, or the like, unfortunately, it may fail, because the equipment works differently. It does not always detect motion at the moment we would like it to work (this is my case). A big plus for low power consumption. It is stated in the note that it is about 50 uA, while I came across a model with a current consumption of 120 uA, but it will still work for battery-powered applications. I personally miss the dusk sensor, but for the money it is understandable :)
If there were still housings for the sensor ...
Works properly
