1.The working principle consists of using FMCW FM Continuous Wave to detect human targets in the defined space, combined with radar signal processing and a precise algorithm for detecting the human body, to achieve highly sensitive detection of human presence status, which can detect the human body in motion and in a stationary state and can calculate the distance of the target and other auxiliary information. 2.The product is mainly used indoors to detect whether there are movements or micro movements of the human body in the area and to output the results in real time. The maximum detection distance is up to 6 meters and the resolution is 0.75 m. A configuration tool is provided to configure the detection distance range, detection sensitivity in different intervals, unattended delay time, etc. 3.LD2410C is a highly sensitive 24 GHz radar sensor module for human presence detection.
