Product Description
The DFRobot Gravity: mmWave C4001 24GHz Human Presence Detection Sensor (12 Meters, I2C & UART) is a compact mmWave presence radar sensor module for human presence and motion detection. Operating at 24 GHz, it is intended for applications that require reliable detection even when visible movement is limited or intermittent.
The module provides presence detection up to 8 m and motion detection with ranging up to 12 m. With a 100° horizontal detection angle and support for both I2C and UART, it can be integrated into microcontroller, embedded, and automation systems. The Gravity interface simplifies electrical connection within compatible DFRobot ecosystems.
