Suitable for home, office, school, and similar environments. 180degree motion sensor switch: detects movement within a wide field and activates the connected load immediately when motion is detected. Automatic on/off control: lights turn on automatically when motion is detected and turn off after a preselected delay. Delay period is adjustable from 5 seconds to 8 minutes. Energy efficiency: designed for low heat and low power consumption, helping reduce energy use without sacrificing performance. Smart occupancy behavior: when people enter the sensing range, the load turns on automatically; when people leave, the sensor delays shutdown to prevent unnecessary lamp operation. Practical and reliable operation: suitable for standard lighting loads and conventional lamps, providing hands control in daily use. Use scenarios: Hallways and corridors in homes or offices: lights illuminate as you walk through and automatically turn off after you pass, saving energy. Restrooms or small offices: occupancybased lighting ensures light is on only during use. Classrooms or study areas: provides automatic lighting for occupied periods and a shortdelay shutdown after the room becomes empty, reducing wasted electricity.
