LD2412 is a wide-angle + long-distance human presence detection millimetre wave radar sensor, its working principle is to use FMCW frequency modulated continuous wave, the detection of human targets in the set space, combined with the radar signal processing, accurate human sensing algorithms, to achieve high sensitivity human presence state sensing, can identify the human body in motion and at rest, and can be calculated to the target distance and other auxiliary information. It is mainly used in indoor scenes, sensing whether there is a moving or slightly moving human body in the area, and outputting detection results in real time. The maximum sensing distance is up to 9 metres, with a distance resolution of 0.75 m. Visual configuration tools are provided to easily configure the range of sensing distance, sensing sensitivity and unoccupied delay time in different zones to suit different specific application requirements. Support GPIO and UART interface, plug and play, flexible application in different intelligent scenes and terminal products.
