LD2410C is a high sensitivity 24GHz human presence sensing module. The working principle is to use FMCW FM Continuous Wave to detect human targets in the set space, combined with radar signal processing, accurate human body sensing algorithm, to realize high sensitivity human presence state sensing, which can recognize the human body in motion and in a stationary state, and can calculate the distance of the target and other auxiliary information. The product is mainly used in indoor scenes to sense whether there is movement or micro-movement of the human body in the area and output the results in real time. 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.
