Features: This product is a energy-saving light switch with high sensitivity detector. It uses microwave radar as a control signal source to detect human movement. When someone enters the detection zone, light will turn on immediately. It supports sensor distance and time delay setting, convenient to use. Radar scanned signal can penetrate plastic, glass, ceiling, wooden door, and thin wall. Easy to install, suitable for LED lights, incandescent bulb, energy saving lamp. Great for closet, basement, laundry room, garage, bathroom, aisle and stairs.
