Product Description: The LD2450 is a motion target tracking sensor module from the Hilink 24G millimeter wave radar series, which includes extremely simplified 24 GHz radar sensor hardware and intelligent algorithm firmware. The solution is mainly used in general indoor scenarios such as homes, offices and hotels to enable the location tracking of moving human bodies. Motion target tracking is to track the position of the moving target in the region in real time, and realize the distance, angle and speed measurement of the moving target in the region. The sensor hardware consists of an AloT millimeter wave radar chip, a high performance one-transmitter-two-receiver microstrip antenna and a low cost MCU and peripheral auxiliary circuitry. The intelligent algorithm firmware uses FMCW waveforms and the radar chip's proprietary advanced signal processing technology. It supports serial output of detection data, which is plug-and-play and can be flexibly applied to different smart scenarios and end products.
