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!
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 delay (most leave this as is) and right is the sensitivity. Turning that right dial anti-clockwise will to reduce sensitivity.
Pin Jumper (re-triggering)
The pin jumper can be set to 'H' or L' (H is the option closest to the edge). H is the most commonly used setting:
- 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)
