The LD2410C is a 24Ghz millimeter wave radar human presence sensor module. It uses FMCW frequency modulated continuous wave to detect human targets in the set space, combined with radar signal processing and accurate human body sensing algorithms. The sensor can detect human movements, micro movements, standing, sitting, and lying down, and output detection results in real-time. It has a wide range of applications, including security systems, smart homes, and automation. The sensor is compact, plug and play, and supports GPIO and UART outputs.
