ME73MS01 is a high-sensitivity 24GHz millimeter wave FMCW human presence detection radar module. Different from traditional radars that detect large movements of human movement or small body movements to determine the presence of human body, the main feature of this module is that it has the function of detecting small movements such as human breathing on the basis of the functions of traditional human body sensing radar to determine the presence of human body. The module adopts FMCW modulation and can output the distance of the target at the same time. This product can detect whether there is someone in the room, and is highly reliable and high-performance.
