DFRobot Gravity Digital 10.525 GHz Microwave Sensor Motion Detection Module
The DFRobot Gravity Digital 10.525 GHz Microwave Sensor is a Doppler radar motion detection module compatible with 5V microcontrollers like Arduino and Raspberry Pi. It provides reliable, non-contact motion sensing of both living and non-living objects, unaffected by ambient temperature, light, or dust.
Features
- 10.525 GHz Doppler radar for precise motion detection independent of ambient temperature.
- Adjustable detection range from 2 to 16 meters via onboard potentiometer.
- Gravity 3-pin interface (Digital, VCC, GND) for plug-and-play integration with Arduino and other 5V systems.
- Robust performance with immunity to environmental factors like humidity, noise, and visible light.
- Safe, low-power RF output with a minimum EIRP of 13dBm.

This sensor operates on the Doppler radar principle, emitting a continuous 10.525 GHz microwave signal and analyzing the frequency shift in the reflected wave to detect motion. This method provides superior performance compared to passive infrared (PIR) sensors, as it is not affected by ambient temperature and can sense movement through many non-metallic materials.
Designed for industrial-grade reliability, the module features strong resistance to radio frequency interference and environmental contaminants. Its digital output provides a simple high/low signal for motion events, making it easy to integrate into security systems, automation controls, and data acquisition setups using common microcontrollers and industrial PLCs.
