Miniature PIR Motion Sensor

This miniature PIR sensor is designed for motion detection. It uses pyroelectric sensor to detect motion by measuring changes in the infrared levels emitted by surrounding objects. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the 'OUT' pin will go high for 2.5 seconds.

Runs on 3.3V to 15V power. Sensing range is about 3.5 meters.

Dimensions: ø16 x 11.6mm
