The Ultimate Guide to Microwave Sensors: Working Principle, …
Working Principle of Microwave Sensors. Microwave sensors operate on the principle of the Doppler effect or radar technology. They emit continuous microwave signals, which bounce off objects in their detection area and return to the sensor. When there is no motion, the reflected signals have the same frequency as the emitted signals.
