LD2412 is a high sensitivity 24GHz human presence sensing module developed by Electronics. Its 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. This product is mainly used in indoor scenes, sensing whether there is a moving or slightly moving human body in the area, and outputting detection results in real time. The maximum sensing distance is up to 9 meters with a distance resolution of 0.75 m. A visual configuration tool is provided to easily configure the range of sensing distance, sensing sensitivity and unoccupied delay time for different zones. Provides visualization configuration tools to easily configure the sensing distance range, sensing sensitivity in different zones, and unoccupied delay time, etc., to adapt to different specific application requirements. Support GPIO and UART output, plug and play, can be flexibly applied to different intelligent scenes and terminal products.
