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's motion. Friendly and convenient, safe and energy-saving.Features: Infrared Sensor: It can detect human movement by detecting infrared ray emitted by human body.It has high and stable sensitivity and can automatically identify day and night.Automatic turns on/off depended on people's motion, which can effectively save energy and improve efficiency.Waterproof and dustproof, can be used indoors and outdoors. Available in corridors, toilets, stairways, balconies, bathrooms, garages, etc. Specifications:Condition: 100% Brand NewMaterial: PVCItem Type: Lighting Sensor SwitchColor: WhiteWorking Voltage: AC110-240VRated Load: 1200W (10A)Detecting Angle: Left and Right 160°, Up and Down 25°Detecting Distance: 10±2MWaterproof Rate: IP44Size: Approx. 8.5 * 6 * 9.5cm / 3.3 * 2.4 * 3.7inchWeight: Approx. 150g / 5.3ozPackage List:1 * Infrared Sensor Switch1 * AccessoriesNote:1. When the light is bright enough, it will not turns on, it is energy saving. If you need it to induce in daylight, you need to adjust it to daylight induction mode. 2. Install following the wiring diagram, after the careful check, connect the power supply. 40~80 seconds is needed for preheat.3. Detecting will be affected by the environment and other factors, such as, temperature, walking speed, cloth, glass, etc.4. In order to keep the high sensitivity, please do not install the product in strong light environment and where there is strong cold or heat airflow.5. This device have the function of repeat triggering, when people in the detecting area, triggering the switch, the device will restart the delay time, so the delay time should be calculated on the last triggering.
