Microwave induction is a new type of induction mode without dead angle, based on the principle of radar. Its planar antenna emits electromagnetic waves and receives reflected echoes, which can effectively suppress the interference of high-order harmonics and other clutter; it is highly reliable, safe and convenient. in 37 In the case of degrees, the sensing distance not be shortened. Widely used in a variety of human body induction lighting and anti-theft and other occasions. RCWL-0515 is a microwave sensor module that uses radar technology to detect the movement of objects. Using 2.7G microwave signal detection, the module has the characteristics of high sensitivity, long sensing distance, strong reliability, large sensing angle and wide supply voltage range. Compared with infrared products: the microwave switch has a longer sensing distance, a wide angle, no dead zone, can penetrate glass and thin wood, and can penetrate walls of different thicknesses according to different power, and is not affected by environment, temperature, dust, etc. Working voltage: 3-12V;Working current: 4mA;2.7G operating frequency;Reserved patch and in-line CDS interface;12m typical sensing range;Adjustable sensing distance;Lead-free process; Repetitive trigger time adjustable, Weight: 0.0330693393 pounds, Manufacturer: Ounfhtrttk
