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.
