1. Product introduction

HLK-LD2420 is a high-performance 24 GHz radar module with a send-and-receive antenna. Its human body sensing algorithm adopts millimeter-wave radar distance measurement technology and advanced proprietary signal processing technology of S3 series chips to achieve precise perception of movement, micro-movement and standing human body.

HLK-LD2420 is mainly used to detect whether there is movement or slight movement of the human body in the indoor scene perception area, and refresh the detection results in real time. It has a maximum sensing distance of 8 m for a moving human body. It can easily configure the sensing distance range, sensing sensitivity in different intervals and refresh time. It supports GPIO and UART interfaces, plug and play, and can be flexibly applied to different smart scenarios and terminal products. .

3. Application scenarios

The HLK-LD2420 human body sensing sensor can detect and identify moving, standing and still people, and is widely used in various AIoT scenarios, covering the following types:

Smart home

Perceive the existence and distance of the human body, and report the detection results for the main control module to intelligently control the operation of home appliances.

Smart business

Identify the approach or distance of the human body within the set distance interval; turn on the screen in time, and keep the device always on when the human body is present.

Smart security

Induction access control, building intercom, electronic peephole, etc.

Smart lighting

Recognize and sense the human body, accurately detect the position, and can be used for lighting equipment in public places (sensing lights, bulb lights, etc.).
