Hailingke 24G Gesture Recognition Millimeter Wave Radar LD2450A Human Proximity Sensing Switch Radar Module--EngrWorld

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 LD2450 is a motion target tracking sensor module from the Hi-link 24G millimetre 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. The sensor hardware consists of an AloT millimetre 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.
