Product Introduction

LD2412 is a high sensitivity 24GHz human presence sensing module developed by Hi-Link. Its working principle is to use FMCW FM continuous wave to detect the human body target in the set space, combined with radar signal processing and accurate human body sensing algorithm, to achieve highly sensitive human presence state sensing, can identify the human body in motion and static state, and can calculate the distance of the target and other auxiliary information.

This product is mainly used in indoor scenes, sensing whether there is movement or micromovement of the human body in the area, real-time output of detection results. The maximum sensing distance can reach 9 meters, and the distance resolution is 0.75m. Provide visual configuration tools, which can easily configure the induction distance range, induction sensitivity of different intervals and unmanned delay time, etc., to adapt to different specific application requirements.

Support GPIO and UART output, plug and play, can be flexibly applied to different intelligent scenarios and end products.

Solution advantages

LD2412 human sensing module adopts 24GHz millimeter wave radar sensor technology, which has obvious advantages in human sensing applications compared with other solutions:

• In addition to being sensitive to the moving human body, it can also be sensitive to the stationary, micro-moving, sitting and lying human body that cannot be identified by traditional solutions;

• Good environmental adaptability, the induction effect is not affected by the surrounding environment such as temperature, brightness, humidity and light fluctuations;

• Good shell penetration, can be hidden in the shell inside the work, no need to open holes on the surface of the product, improve the product beauty;

• The maximum sensing distance and sensitivity on each distance door can be flexibly configured to achieve flexible and fine personalized configuration;

Application scenarios

The LD2412 human body sensing module can detect and identify the human body in motion, micro-movement, standing and sitting, and supports multi-level adjustment. It can be widely used in various scenarios of AIoT. The common types are as follows:

• Human body induction light control

Sensing the presence of people in the space, automatic control of lighting, such as lighting equipment in public places, various induction lights, bulb lights, etc.

• Human body induction awakening of advertising screen and other devices

Automatically turns on when someone comes, automatically sleeps when no one is around to save power, and information delivery is more accurate and efficient.

• Life safety protection

UV lamp work protection, to prevent the UV lamp from being turned on when there are peoplearound and causing personal injury;

Automatic detection and alarm of dangerous places to prevent people from entering specifichighrisk spaces, such as high-risk places entered by personnel from coal mine blasting；

• Smart home appliances

When there is no one in the room for a long time, the TV, air conditioner and other electrical appliances are automatically turned off, saving energy and safety.

• Intelligent security

Detection and identification of people intruding, staying, etc. within the specified range.
