HLK-LD2410 is a high-sensitivity 24GHz human presence status sensing module. Its working principle is to use FMCW frequency-modulated continuous wave, to detect human targets in the set space, combined with radar signal processing, accurate human body induction algorithm, to achieve high sensitive human presence status sensing, which can identify the human body in motion and stationary state, and can calculate auxiliary information such as the distance to the target.
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. Farthest sensing distance up to 6 meters, distance resolution 0.75m. Provides a visual configuration tool, which can easily configure the sensing distance range and sensing in different intervals sensitivity 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.
Plug and play, easy assembly. The sensing distance is up to 5 meters. Large detection angle, coverage up to ±60 degrees. Accurate identification within the interval, support the division of the sensing range, and shield the interference outside the interval
Multi-level intelligent parameter adjustment to meet the needs of scene changes. Visual debugging and configuration tools. Supports various installation methods such as ceiling hanging and wall hanging

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:
1. In addition to being sensitive to moving human bodies, it can also sensitively sense static, micro-moving, sitting and lying human bodies that c
