LD2410B is a high-sensitivity 24GHz human presence status sensing module. 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 precise 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. Product Features and advantage Plug and play, easy assembly The longest 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 can be realized through Bluetooth or serial port to meet the needs of scene changes Visual debugging and configuration tools Small and simplified, the minimum size is only 7mm x 35mm Supports various installation methods such as ceiling hanging and wall hanging.
