HLK-LD2410B+BLE 24Ghz Human Micromotion Detection Radar Sensor Module Test Board Kit

LD2410B is a highly sensitive 24GHz human presence status sensing module developed by Hi-link. It operates based on the principle of using FMCW (Frequency-Modulated Continuous Wave) to detect human targets within a defined space. Through the combination of radar signal processing and a precise human body sensing algorithm, it achieves high-sensitivity sensing of human presence status, capable of identifying both moving and stationary human bodies. Additionally, it can calculate auxiliary information such as the distance of the target.

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

Product parameters

• Plug and play, facilitating easy assembly.

• The longest sensing distance can reach up to 5 meters.

• Large detection angle, with a coverage of up to ±60 degrees.

• Accurate identification within the specific interval, permitting the division of the sensing range and blocking interference from outside the interval.

• Multi-level intelligent parameter adjustment to fulfill the requirements of scene alterations.

• Visual debugging and configuration tools are available.

• It is small and simplified, with the minimum size being only 7mm x 35mm.

• Supports various installation methods including ceiling hanging and wall hanging.

• Operates in the 24GHz ISM band, conforming to FCC and CE spectrum regulations.

• 5 - 12V wide voltage power supply.

• The ultimate cost-effective option.

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:

• 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.；

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

• 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；

• 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.

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.
