Integrated Light Control Sensor The built-in light control sensor intelligently recognizes ambient brightness and only activates the load when the surrounding light is below a certain level. This prevents unnecessary lighting during daytime or in well-lit environments, helping to extend lamp life and reduce power consumption. Wide Voltage Compatibility This automatic wall-mounted motion sensor switch supports 110V~220VAC input, making it suitable for a wide range of residential and commercial electrical systems. Ideal for homes, offices, corridors, stairways, basements, garages, and storage rooms. Automatic On/Off PIR Infrared Control Equipped with a high-sensitivity PIR (Passive Infrared) sensor, the switch accurately detects human body movement within its sensing range. Lights turn on automatically when motion is detected and turn off after a preset delay when no movement is sensed, improving convenience and savings. Saving & Cost Effective By combining motion detection with light level sensing, this switch significantly reduces wasted electricity. It is especially effective in areas where lights are frequently left on by mistake. Lower usage can help reduce your utility bills over time., Weight: 0.2425084882 Pounds, Manufacturer: Xnuiasqe
