HLK-LD2410C 24GHz Human Precense Radar Module

LD2410C is a highly sensitive 24GHz human presence status sensing module developed by Hi-link. Its operational principle is to employ FMCW frequency-modulated continuous waves to detect human targets within the defined space. Through the combination of radar signal processing and accurate human body sensing algorithms, it achieves high-sensitivity human presence status sensing and is capable of distinguishing between moving and stationary human bodies. Additionally, auxiliary information such as the target's distance can be computed.

This product is primarily utilized in indoor settings to detect the presence of a moving or slightly moving human body within an area and provide real-time output of the detection results. The maximum sensing range can extend up to 5 meters, with a distance resolution of 0.75m. It offers a visual configuration tool that enables easy configuration of the sensing distance range, sensing sensitivity in different intervals, and unmanned delay time, etc., to meet various specific application requirements.
It supports GPIO and UART output, is plug-and-play, and can be flexibly applied to different smart scenarios and terminal products.

Solution Advantage

LD2410C human body sensing module adopts 24GHz millimeter wave radar sensor technology. Compared with other solutions, it has obvious advantages in human body sensing applications:

• It is not only responsive to a moving human body but also can sensitively detect the static state, minute movements, and sitting and lying postures of a human body, which traditional solutions are incapable of recognizing.
• It exhibits excellent environmental adaptability, as the sensing performance remains unaffected by surrounding environmental factors such as temperature, brightness, humidity, and light fluctuations.
• It has good shell penetration capabilities and can operate concealed within the shell without the need for surface openings on the product, thereby enhancing the product's aesthetic appearance.
• It allows for flexible configuration of the maximum sensing distance and the sensitivity at each distance interval, enabling flexible and fine-tuned customization.

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.
