PIR Motion Sensor, Mini, Breadboard-friendly, with 3 Pin Header

PIR sensors are used to detect motion from pets/humanoids from about 5 meters away (possibly works on zombies, not guaranteed). This sensor is much smaller than most PIR modules, which makes it great for unobtrusive projects. It’s also fully contained – only needs power and ground, and it’s breadboard or perfboard friendly.

Usage is super simple: You can power it from 3 to 12V DC, there’s an onboard regulator. Digital signal output is 3.3V high/low. The signal goes high when motion is detected and stays high for another 2 seconds, so you have plenty of time to read the value.

  • Connect pin #1 to ground (there’s a tiny minus – sign next to the pin)
  • Connect pin #2 to the output signal (there’s a tiny O next to this pin that goes high and low)
  • Connect pin #3 to power (there’s a tiny plus + sign next to the pin)

The attached 13.8mm diameter lens is focused to 2 to 5 meters away with a 100-degree spread.

Notes:

  • PIR sensors and the Raspberry Pi sometimes don’t get along – if you’re having false trigger reports, make sure the PIR Sensor is far away from the Pi
