Product Description

The DFRobot mmWave - C4001 24GHz Human Presence Detection Sensor (25 Meters, UART) is a compact mmWave presence radar sensor module designed for detecting human presence and motion. The module operates in the 24 GHz band and is specified for detection ranges up to 25 m. Its UART interface supports integration into embedded systems, microcontroller platforms, and industrial prototype applications.

The sensor module uses millimeter-wave technology and is described by the manufacturer as featuring FMCW modulation and strong anti-interference performance. It is suitable for applications that require robust presence or motion sensing where optical sensing methods are less suitable. The compact module format supports installation in device housings and fixed-position systems.
