The PIR Motion Sensor Detector Module is used for motion detection. This is also known us “PIR”, “Passive Infrared” and “IR Motion” sensor. The module has an on-board pyroelectric sensor, conditioning circuitry and a dome shaped Fresnel lens. It is used to sense movement of people, animals, or other objects. They are commonly used in burglar alarms and automatically-activated lighting systems.
