1. Product introduction
LD2410 is a high-sensitivity 24GHz human presence status sensing module developed by Hi-
Link Electronics. 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 accurate human
body sensing algorithms, it realizes high-sensitivity sensing of human presence status, 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.
Supports GPIO and UART output, plug and play, and can be flexibly applied to different smart
scenarios and terminal products.
