Hi-Link HLK-LD2402, 24GHz Human Presence Radar Sensor is a static human life presence sensor of Hi-Link, which includes a minimalist 24GHz sensor hardware and human micro-motion sensing intelligent algorithm firmware. The hardware is equipped with AIoT millimeter wave sensors, high-performance 24GHz one-transmit-one-receive antennas and peripheral circuits; the human presence sensing algorithm uses millimeter wave radar distance measurement technology and radar chip’s advanced proprietary radar signal processing technology to achieve accurate perception of motion, micro-motion and human presence. The human presence sensing intelligent algorithm firmware is mainly used in indoor scenes to sense whether there is motion, micro-motion or human presence in the area, and refresh the detection results in real time. The maximum sensing distance of HLK-LD2402 for moving human bodies is 10m, and the sensing distance range, trigger and hold thresholds in different intervals, and unattended reporting time can be easily configured. Hi-Link HLK-LD2402, 24GHz Human Presence Radar Sensor supports GPIO and UART interfaces, plug-and-play, and can be flexibly applied to different smart scenes and terminal products. At the same time, it supports automatic generation of detection thresholds, reduces manual debugging, improves detection accuracy, simplifies the installation process, and facilitates large-scale deployment.
