Hi-Link HLK-LD2420 is a high-performance 24 GHz radar module with one transmitter and one receiver antenna. Its human sensing algorithm uses millimeter-wave radar distance measurement technology and the advanced proprietary signal processing technology of S3 series chips to achieve accurate sensing of moving, micro-movement, and standing human bodies. HLK-LD2420 is mainly used in indoor scenes to sense whether there is a moving or slightly moving human body in the area and refresh the detection results in real-time. It has a maximum

sensing distance of 8 m and can be easily configured to sense the distance range, sensitivity, and refresh time in different zones. It supports GPIO and UART interface, which is plug-and-play and can

be flexibly applied to different smart scenarios and end products.
