Automatic lighting with ambient-light sensing The microwave detector turns lights on when you enter and automatically switches them off when you leave. It detects ambient light to avoid unnecessary illumination. The sensor can penetrate glass, lampshades and most surfaces, providing flexible placement. It delivers energy savings and is not affected by external noise or nearby objects. Wide range of applications The microwave sensor emits microwave signals to detect moving objects, working like a radar tachometer. It is suitable for LED lights, incandescent bulbs and energy-saving bulbs. Ideal for closets, basements, laundry rooms, garages, bathrooms, hallways and stairs. Safe to use Manufactured to strict quality standards, it offers solid safety performance. The microwave power emitted by the sensor is less than 0.2 mW, about 1/1000 of a typical mobile phone. The recommended installation height is 8–12 feet; since mobile phones are usually used within 3 feet, this radar motion sensor can be used safely and confidently. Comprehensive detection The sensor light switch provides 360-degree detection with a maximum range of 10 m. Radar waves can penetrate glass, paper, plastic and thin walls, so installation location is flexible and the sensor can detect objects before they are directly in view.
