LD2410B is a high-sensitivity 24GHz human presence status sensing module. 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 can be .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. The farthest sensing distance can reach 5 , 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 application needs.Support GPIO and UART output, plug and play, and can be flexibly applied to different smart scenarios and terminal .Product Features and advantagePlug and play, easy assemblyThe 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 intervalMulti-level intelligent parameter adjustment can be realized through Bluetooth or serial port to the needs of scene changesVisual debugging and configuration toolsSmall and simplified, the minimum size is only 7mm x 35mmSupports various installation methods such as ceiling hanging and wall hanging.Material: PCBcolour: BluePackage Contents:1 x Radar Sensor ModuleOnly the above package content, other are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
