Body induction switch with PIR infrared motion sensor for automatic light control. The sensor detects human body heat to turn lighting on when someone enters the sensing area and off after the person leaves, reducing unnecessary run time and lowering power consumption. Key benefits Hands operation: automatic on and off based on human presence, ideal for frequently used but not continuously lit areas. Energy efficient use: light stays on only while the sensing area is occupied, helping to reduce wasted electricity. Simple installation and wide compatibility: fits many lamp types and works with a broad DC voltage range. Features and specifications Detection: passive infrared (PIR) human body sensor that responds to body temperature. Operating voltage: DC 9 V to 60 V. Output power: less than 18 W. Sensing distance: 1 to 5 m, depending on ambient temperature and placement. Induction angle: 120 degrees. Light control: activates at night or when ambient light is below 10 lux. Hold time: about 20 to 25 seconds after the last detection. Operating temperature: from 20 C to 40 C. Material: PC flame retardant housing. Compatible lamps: energy saving lamps, incandescent lamps, ceiling lamps, and downlights. Installation and use tips Install in locations where brief automatic lighting is useful and continuous lighting is not required. Mount in a position with a clear view of the detection area for performance and avoid blocking the sensor. Keep in mind sensing distance can vary with temperature and placement. Test placement to confirm reliable detection. Typical applications Corridor or stairway lighting that turns on when someone passes and turns off shortly after they leave. Bathroom or kitchen lights that activate on entry and switch off automatically to avoid long unattended operation. Garage, balcony, or storage area lighting where automatic activation improves convenience and reduces manual switching. Package includes 1 body induction switch This sensor switch provides reliable automatic lighting control with straightforward installation and broad lamp compatibility for everyday indoor lighting needs.
