DFRobot Gravity C4001 mmWave Human Presence Detection Sensor (12 m Range) - I2C & UART
The DFRobot Gravity C4001 is a 24GHz FMCW mmWave radar sensor module designed for precise human presence and motion detection up to 12 meters. Featuring I2C and UART interfaces via a Gravity PH2.0 connector, it integrates seamlessly with Arduino, Raspberry Pi, ESP32, and other 3.3V logic development platforms.
Features
- 24GHz FMCW mmWave radar with a 12m motion detection and 8m static presence sensing range.
- Dual communication via I2C (address 0x2A) and UART (9600 baud) through a Gravity PH2.0 interface.
- Wide 100° x 80° beam angle for broad coverage area detection.
- Robust performance across -40°C to +85°C, immune to light, dust, noise, and weather interference.
- Measures distance (1.2-12m) and speed (0.1-10m/s) for comprehensive motion analysis.

The Gravity C4001 millimeter-wave sensor utilizes Frequency Modulated Continuous Wave (FMCW) radar technology at 24GHz to detect subtle human presence and motion through obstacles and in challenging environmental conditions. Its advanced signal processing distinguishes static human presence from dynamic motion, providing reliable data for automation and monitoring systems.
Engineered for industrial and smart environment applications, the module outputs precise distance and velocity data via a simple serial protocol. Its compact form factor and Gravity interface standard simplify integration into prototypes and embedded systems requiring robust, non-intrusive presence sensing.
