Product Description:
RCWL-0515 is a microwave induction module that uses Doppler radar technology to specifically 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, wide supply voltage range and so on.
Microwave induction is a new type of induction mode without dead angles, based on the principle of Doppler radar. Its antenna emits electromagnetic waves and receives reflected echoes, which can effectively suppress the interference of higher-order harmonics and other clutters; it has strong reliability, safety and convenience.
Compared with infrared products: the microwave switch has a longer sensing distance, a wide angle, no dead zones, can penetrate glass and thin wooden boards, and can penetrate walls of different thicknesses according to different powers, and is not affected by environment, temperature, dust, etc., at 37 In the case of degrees, the sensing distance will not shorten. Widely used in various human induction lighting and anti-theft alarm and other occasions.
