The microwave 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:
Non-contact detection
Readings not affected by temperature, humidity, noise, air, dust or light - suitable for harsh environments
Strong resistance to radio frequency interference
Low output, unharmful to human
Wide detection range and high velocity
Supports non-living object detection
