Infrared pir motion sensor 3*4mm window, wide angle Long distance High sensitivity to human motion Direct supply, good price The Pyroelectric InfraRed(pir) motion detection sensor detects infrared radiation on the basis of the characteristics that the polarization of pyroelectric material changes with temperature. Feature for pir sensor: Dual compensated sensing elements in the PIR sensor are applied to suppress the interference resulting from temperature variation. As a result, the operating stability of the sensor is greatly improved. Typical Applications for motion sensor 1. Security systems 2. Burglar alarms 3. Visitor acknowledgement 4. Lighting switch control 5. Intellectualized toy, etc. 100pcs/box, 18000pcs/CTN.
