HALJIA 5PCS Microwave Radar Sensor RCWL-0515 Switch Module Human Intelligent Induction Board Detector Module

RCWL-0515 is a microwave sensor module using Doppler radar technology, specifically used to detect object movement. 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. Microwave induction is a new type of induction mode without dead angles, based on the principle of Doppler radar. Its planar antenna emits electromagnetic waves and receives reflected echoes, which can effectively suppress the interference of high-efficiency harmonics and other clutter. Strong reliability, safe and convenient. Compared with infrared products: the microwave switch has a longer sensing distance, a wide angle, no dead zones, can pass through glass and thin wooden boards, and can pass through walls of different thicknesses according to different powers, and is not affected by environment, temperature, dust and so on. In a 37 degree environment, the sensing distance will no
