1,This product is a 3.7GHz microwave induction mobile module, which can effectively detect objects moving inductively. 2,The module has a main control chip with a built-in high-precision algorithm unit, which can effectively filter out environmental interference. 3,Good stability, strong anti-interference, wide sensing range and high sensitivity. 4,The control signal output delay time is adjustable and accurate. 5,An externally connected photosensitive diode prevents the product from working during the day (it can also be adjusted to work during the day). 6,The induction penetrating force is strong, and it can penetrate wooden board, glass, wall, etc. (metal cannot penetrate). 7,When someone enters the detection area, the light will be on immediately. When people leave and the delay time is up, the light will be off. 8,It is suitable for automatic lighting, automatic ventilation of exhaust fans, and other electrical control functions, such as corridors, bathrooms, basements, warehouses, garages and other places.
