It is a high sensitivity 24GHz millimeter wave human presence detection radar module. Different from the traditional radar, the main feature of this module is that on the basis of the function of the traditional human-body induction radar, it also has the ability to detect and accumulate small-scale movements such as human respiration to determine the function of the existence of the human body. Therefore, compared with traditional Doppler radar, it has presence detection within a certain range, with higher accuracy, and is not easy to miss reports.
