LD2411S is a 24GHz ranging radar sensor module, the working principle is to utilize the FMC W FM continuous wave. The working principle is to use FMC W FM continuous wave to detect the target in the set space, combined with radar signal processing, accurate sensing algorithms. Accurately senses the distance and status information of micro-motion/movement objects.
Configuration tools are available to modify the sensing distance range, sensing sensitivity and delay time.
