The product is mainly used in indoor scenes to sense whether there is movement or mini-movement of the human body in the area and output the results in real time. LD2410B is a high-sensitivity 24GHz human presence sensing module. The working principle is to use FMCW frequency modulated continuous wave to detect human targets in a set space, combined with radar signal processing and precise human sensing algorithm, to achieve high-sensitivity human presence state sensing, which can identify human bodies in motion and stationary states and calculate Auxiliary information such as the distance to the target. The sensing distance is up to 6 meters, and the resolution is 0.75m. A configuration tool is provided to configure the sensing distance range, sensing sensitivity in different intervals, unattended delay time, etc. Supports GPIO and UART output, plug-and-play and can be flexibly applied to different smart scenarios and terminal products., Weight: 0.01322773572 Pounds, Manufacturer: Yoeruers
