Hlk-ld2410B Human Presence Sensor Radar Module For Smart Home Automation And Security

LD2410B is a high-sensitivity 24GHz human presence status sensing module developed by Hilink 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 and accurate 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.

Application scenarios:

• Human body sensor light control
• Human body induction wake-up of advertising screen and other equipment
• Life safety protection
• Smart home appliances
• Intelligent security
