This switch is based on infrared technology, it will automatic turn on when the sensor detects the change of the infrared spectrum of the human body in the sensing range. High and stable sensitivity, automatic turns on/off depended on people movation. Friendly and convenient, safe and energy-saving. Features: Infrared PIR Motion Sensor: It can detect human movement by detecting infrared ray emitted by human body. 140 Degrees Cone Angle Detecting Range: The sensing distance can reach 8-10m. High and stable sensitivity, effectively save energy and improve efficiency. Light Control & Delay Adjustment: With the adjustable range and button, you can choose the apposite time or mode according your needs so as to save your energy. Wide Applications: Widely used on the motion-activated lighting, corridors, bathrooms, basements, warehouses, garages and other places, low-power electrical appliances and other functions. Good Safety & High Durability: Made of high quality and refractory material, make it safer and more reliable. Easy Installtion: IR sensor switch a wireless switch, easy to use and installation without wiring with the lights.
