HLK-LD2410B+BLE 24Ghz Human Presence Body Induction Distance Detection Radar Sensor Module support GPIO and UART

LD2410B is a high-sensitivity 24GHz human presence status sensing moduledeveloped by Hi-link. Its working principle is to use FMCW frequency-modulated continuous waves to detect human targets in the set space. Combined with radar signal processing and precise human body sensing algorithms, it realizes high-sensitivity human presence status sensing, and can identify human bodies in motion and stationary states. And auxiliary information such as the distance of the target can be calculated.

This product is mainly used in indoor scenes to sense whether there is a moving or micro-moving human body in the area, and output the detection results in real time. The farthest sensing distance can reach 5 meters, and the distance resolution is 0.75m. Provides a visual configuration tool, which can easily configure the sensing distance range, sensing sensitivity in different intervals and unmanned delay time, etc., to adapt to different specific application needs.

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

Solution Advantage

LD2410 human body sensing module adopts 24GHz millimeter wave radar sensor technology. Compared with other solutions, it has obvious advantages in human body sensing applications:

1.In addition to being sensitive to the moving human body, it can also sensitively sense the static, fretting, and sitting and lying movements of the human body that cannot be recognized by traditional solutions.；

2.It has good environmental adaptability, and the sensing effect is not affected by the surrounding environment such as temperature, brightness, humidity and light fluctuations；

3.With good shell penetration and can be hidden in the shell to work without opening holes on the surface of the product, which improves the aesthetics of the product；

4.Flexible configuration of the farthest sensing distance and the sensitivity on each distance door for flexible and fine-tuned personalization；

Application

* Human body sensor light control

It senses whether there is someone in the space, and automatically controls lights, such as lighting equipment in public places, various sensor lights, bulb lights, etc.

* Human body induction wake-up of advertising screen and other equipment

Automatically turn on when people come, and automatically sleep when no one comes to save power, 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 people around and causing personal injury

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