Energy-saving motion sensor switch using microwave radar as the control signal source to detect human movement. When someone enters the detection range, the light turns on immediately. The radar signal can penetrate plastic, glass, ceilings, wooden doors, and thin walls. It supports adjustment of sensor distance and time delay, convenient to use. Easy to install, suitable for LED lights, incandescent bulbs, energy-saving lamps. Perfect for closets, basements, laundry rooms, garages, bathrooms, driveways, and stairwells. Recommended wall mounting height: 1.5-1.8m, ceiling mounting height recommended: 3 to 6m. Features: Color: White Type: 12-24V SK-807K-DC, 220V-240V SK-600, 220V-240V SK-700 (optional).
