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: 1. When pedestrians into the sensing range light will start automatically, when they leave light will delay and shut down automatically. 2. With light-sensitive control, it will not turn on the light during daytime or strong light conditions, or it can be set to turn on the light any environment. 3. It opens in the delay period, if there is no human activity, it has the function of freely adjusting the delay time within the appropriate range. 4. With effective LED fault indication for easy installation and failure analysis. 5. Built-in temperature compensation chip to reduce the sensing distance affected by temperature.
