LD2410C-24G mmWave Human Presence Radar Sensor Module

HLK-LD2410C is a 24GHz high-sensitivity human presence status sensor module developed by Hi-Link Electronics. Its working principle is to use FMCW frequency-modulated continuous wave to detect human targets in the set space, combined with radar signal processing, accurate human body induction algorithm, to achieve high sensitive detection of human presence status, which can identify the human body in motion and stationary state, and can calculate auxiliary information such as the distance to the target.

This product is mainly used in indoor scenes to detect whether there is a moving or micro-moving human body in the area, and output the detection results in real time. The farthest detection distance is up to 5 meters, and the distance resolution is 0.75m. It provides a visual configuration tool, which can easily set the detection distance and detection in different ranges, sensitivity and unmanned delay time, etc., to adapt to different specific application needs.

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

Module Benefits

The LD2410 human body sensor 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 moving human bodies, it can also sensitively sense static, micro-mobile, sitting and lying human bodies that cannot be identified by traditional solutions;

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

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

4. It can flexibly set the farthest detection distance and sensitivity at each distance port to achieve flexible and fine personalized configuration.

Application scenarios

The LD2410 human body detection module can detect and identify the human body in moving, fretting, standing, sitting and lying down. It supports multi-level parameter adjustment and can be widely used in various AIoT scenarios. The common types are as follows

• Clear control of human body sensor

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

• Human body induction wake-up advertising screen and other equipment

Automatically turn on when people come and automatically sleep when no one comes to save energy, 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 coal mine blasting personnel

• 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.

• Smart security

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