1. LD2410C is a highly sensitive 24GHz radar module for detecting human presence. 2. The product is mainly used indoors to detect whether there are movements or micromovements of the human body in the area and to output the results in real time. The maximum detection distance is up to 6 meters and the resolution is 0.75 m. A configuration tool is provided to configure the detection distance range, the detection sensitivity in different intervals, the unattended delay time, etc. 3. The working principle is to use FMCW (Frequency Modulated Continuous Wave) to detect human targets in the set space, combined with radar signal processing and an accurate algorithm for detecting the human body, to achieve highly sensitive detection of the human presence state, which can detect the human body in motion and in a stationary state and can calculate the distance of the target and other auxiliary information.
