Infrared PIR Sensors (Pyroelectric Resistive)

Infrared-Sensors-for-Smart-Devices Pyroelectric Infrared Sensors (PIRs) are passive infrared sensors measuring infrared (IR) light radiating from objects within the field of view of the PIR Sensor. PIR based motion detectors (also called PID for Passive Infrared Detector) are used widely in security applications measuring movement of people, animals or other objects. Thermopiles are commonly used in lighting systems and burglar alarms. Willow’s Engineers can help you select the most appropriate PIR Sensor for you and assist with custom design.
