A passive infrared (PIR) sensor is an electronic device that detects infrared (IR) light emitted by objects within its field of view and outputs a 5V signal.

Developed by Bbiri Applied ICT Centre Limited, this sensor detects objects emitting infrared radiation and provides a corresponding output. The onboard potentiometer allows for adjustments to both sensitivity and the duration the output remains high.

Additionally, the module features continuous triggering, meaning the output will remain in one state as long as the object stays within its detection range.
