Main Features: The human body induction switch is an intelligent infrared detection sensor, which uses infrared detection to control the load switch. The light is turned on and off by detecting the temperature of the human body. When someone approaches, the sensing device will be triggered to start working. After the person leaves the sensing area, the sensing device will automatically turn off after the set time. Ensure that the light is on when the person comes. The light is off. Realize the effect of energy saving and energy saving to the greatest extent. Users can install the human body sensor in the appropriate environment according to actual needs (such as ceiling lamp, bathroom, kitchen, balcony, warehouse, corridor, staircase, garage, etc., which do not require long lighting Place (with light perception, working in dark). Specification: Working temperature: -20-40℃ Input voltage: AC85V-265V Output voltage: 110V/220V Sensing distance: 1-5 meters (depending on the ambient temperature) Sensing angle; 120° Delay time; about 20-25 seconds Load power: ≤40W Material: ABS Size: 37*28mm/1.46*1.1" Recommended installation hole diameter: 20mm/0.79" Input line length: 200mm/7.87" Output line length: 200mm/7.87" Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-3mm measuring deviation due to manual measurement. Included: 1 X Sensor Switch Integrate circuit and SMT,new type of energy-saving lighting switch. It adopts high sensitivity detector, left and right service field. Motion sensor turns lights ON automatically when motion is detected and OFF after a pre-selected time delay.
