Gravity: Digital 10.525GHz Microwave Sensor (Motion Detection)

The 10.525GHz microwave motion sensor applies the Doppler effect to detect moving objects using microwaves. This differs from the method used by a regular infrared (IR) sensor as microwave is sensitive to a variety of objects that are microwave-reflective, and its sensor readings are not affected by the ambient temperature.

This type of microwave sensor is widely used in industrial, transportation, and civil applications such as measuring vehicle speed, liquid levels, automatic door motion detection, automatic washing, production line material detection and car reversing sensors, etc.
 

2 Magical Sensors from DFRobot

The microwave detection method has the following advantages compared to other methods:

1. Non-contact detection
2. Readings not affected by temperature, humidity, noise, air, dust or light - suitable for harsh environments
3. Strong resistance to radio frequency interference
4. Low output, unharmful to human
5. Wide detection range and high velocity
6. Supports non-living object detection
