PIR sensors are one of the most popular sensors used with the Raspberry Pi and Arduino projects. They're affordable, easy to code, have endless online examples and make some of the coolest projects!

Use these sensors to detect movement in front of your project! We use these sensors in our Raspberry Pi PIR Camera Case!

Pins

You may need to pop the top white plastic dome off of the sensor to see the pin assignments. In the image below we show the usual order of the pins:

PIR Pin Recommended Raspberry Pi Pin
Left pin ("GND") Physical pin 6 (GND pin)
Middle pin ("OUT") Physical pin 11 (GPIO 17)
Right pin ("VCC") Physical pin 4 (5V)

PIR pins

PIR Dials

The two dials control delay (how long before it checks for movement again) and sensitivity.

When looking straight at the dials with the dome at the top, the left dial is used for the delay (most leave this as is) and the right is the sensitivity. Turning that right dial anti-clockwise will reduce sensitivity.

Re-triggering

The pin header and jumper selector can be used to set to re-triggering options. 'H' is the default as this is what most users require and most tutorials you find will be set to 'H', however you can change this:

  • H is 're-triggering' mode. It'll send a signal the entire time something is moving.
  • L is 'non-retriggering' mode. This continually sends signals on and off all the time there is movement (a more erratic option and not recommended)

Applications

  • Switch
  • Motion sensor
  • Thief-guarding system
  • Industrial automation

Specifications

  • Input voltage: DC 4.5~20V
  • Static current: 50uA
  • Output signal: 0,3V (Output high when motion detected)
  • Sentry angle: 110 degree
  • Sentry distance: max 7 m

Revisions

Following customer feedback, as of 04/02/2022 we are now shipping a module with a triggering pin header and selection jumper (previously a solder pad).
