Our microwave sensor emits microwave signals to detect moving object, the same way a radar speed detector works. The ceiling motion sensor sensing and penetrating power is strong, can penetrate wood, glass, wall, etc. Features: Motion sensor with good stability, strong antiinterference, wide sensing range and high sensitivity. Our microwave sensor emits microwave signals to detect moving object, the same way a radar speed detector works. This small motion detector has a clean and modern profile with a classic round shape. The body housing is made with ABS material, gives a beautiful smooth finish. Standard white low profile allows this sensor to blend seamlessly into your ceiling. Ceiling mounted motion sensor Features 360 degree detection with 6 meter sensing range; Radar waves are capable of penetrating glass, paper, plastic and thin wall. When people come, the microwave detector lights are on and the delay time is when people walk.
