mikrobølgebevægelse
Mikrobølgebevægelse, also known as microwave motion, refers to the detection of movement using microwave signals. This technology relies on the Doppler effect, where the frequency of a reflected microwave signal changes if the object it bounces off is moving. A sensor emits microwave signals and analyzes the frequency of the returning waves. If a difference in frequency is detected, it indicates motion.
Microwave motion detectors are known for their ability to penetrate non-metallic obstacles like walls and glass,
The range and sensitivity of microwave motion detectors can be adjusted, and they are often used in
