Pir Motion Sensor Switch（large）

The Pir Motion Sensor Switch works by using infrared radiation emitted by humans or animals. Every object with a temperature above absolute zero releases thermal energy in the form of radiation, and the human body radiates infrared light at wavelengths of 9-10 microns for most of the day. The PIR sensor is tuned to detect this infrared wavelength, and when a human or animal enters its sensing range, the sensor senses a change in infrared radiation and triggers a switch action AC220V IP44 180 degree Rotating adjustable Pir Motion Sensor Detector automatic Outdoor floodlight wall light sensor switch。
