1. Product introduction
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.
