HLK-LD2410 is a high-sensitivity 24GHz human presence status sensing module. working principle is to use FMCW frequency-modulated continuous wave, to detect human targets in the set space, combined with radar signal processing, 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 . This product is mainly used in indoor scenes to sense whether there is a moving or -moving human body in the area, and output the detection results in real time. Farthest sensing distance up to 6 , 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 application needs. Support GPIO and UART output, plug and play, and can be flexibly applied to different smart scenarios and terminal . Plug and play, easy assembly. The longest sensing distance is up to 5 . detection , coverage up to 60 degrees. identification within the interval, support the of the sensing range, and the interference outside the interval Multi-level intelligent parameter adjustment to 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, -moving, sitting and lying human bodies cannot be identified by solutions; 2. It has good environmental adaptability, and the sensing effect is not affected by the surrounding environment such as temperature, brightness, humidity and light fluctuations; 3. It has good shell penetration and can be in the shell to work without opening holes on the surface of the product, which improves the aesthetics of the product; 4. It can flexibly configure the farthest sensing distance and the sensitivity on each distance door to achieve flexible and fine configuration. Module size: 7mmx35mm, 5 pin holes are reserved in the hardware (the default does not match the pins) The pin hole diameter is 0.6mm, and the pin spacing is 1.27mm.
