PIR Sensor Pyroelectric Infrared Motion Detector

A PIR sensor is used to sense motion (usually human motion) within a specified range. They detect small amounts of radiation using an IR sensor. Using a motion sensor is a good way to allow your device to detect if a human (or animal) has entered, exited or approached a specific area. Technical Specs:
