LD2410C is a highly sensitive 24GHz human body presence sensing module. The working principle is to use FMCW frequency modulated continuous wave to detect human targets in a set space. Combined with the precise human body sensing algorithm of radar signal processing, it can achieve high-sensitivity human presence state sensing, and can identify human bodies in motion and stationary states, and can Calculate auxiliary information such as the distance to the target. 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 5 meters, and the distance resolution is 0.75m. Provides a visual configuration tool to easily configure the sensing distance range, sensing sensitivity in different intervals, and unattended delay time. Supports GPIO and UART output, plug-and-play, and can be flexibly applied to different smart scenarios and terminal products.
