PIR Motion Sensor

The PIR Motion Sensor detects movement using passive infrared technology, making it ideal for projects requiring motion-triggered actions. Compatible with both Arduino and Raspberry Pi, this compact sensor outputs a 3.3V logic signal that works seamlessly with 3.3V boards like the Arduino Due and Pro Mini, while still registering as HIGH on 5V boards like the Uno.

Adjustable sensitivity and hold time settings let you fine-tune detection for your specific application. The wide 140° field of view and 3-7m detection range make it suitable for room-scale motion sensing.
