Obstacle sensor module Radar RCWL-0515 emits continuous waves with a frequency of 2.7G, when encountering obstacles, this wave will be reflected and reflected back to the sensor. Radar sensor will receive, calculate the change of transmit frequency and receive frequency. The module is used to detect the movement of objects, people.
The module has high sensitivity, long detection distance, high reliability, large detection angle. The sensor has a compact size for easy installation, the maximum detection distance is about 12-15m, can penetrate some thin plastic, glass, and wooden obstacles, so it is convenient to hide.
The radar sensor is not affected by the environment temperature, dust, etc. The measured signals from the radar sensor are always stable even in adverse environmental conditions. With high frequency transmission with narrow beam, the radar sensor will not be affected by obstacles and is not limited to scanning angle. It is widely used in life such as obstacle detection, human body induction, anti-theft alarm. it can be applied at Garage Lights, Corridor Lights, Sensor Lights, Solar Lights, UV Disinfection Lamp, Human body motion sensing.
