What is a Microwave Motion Sensor?
A microwave motion sensor uses electromagnetic radiation. It emits waves that are then reflected back to the receiver. The receiver analyzes the waves that are bounced back. If there is an object moving in the room,
these waves are going to be altered. The microwave detector is able to identify changes from moment to moment.
Ideally, the receiver should be receiving the same waves back again and again.
Because of the way that microwave motion sensors work, they can be either more sensitive or less sensitive.
They can identify every minute changes (a totally empty house) or be calibrated to require larger-scale movement (to avoid false positives).
How does a Microwave Sensor work?
A Microwave sensor uses high-frequency radio waves operating at 360 degrees. They work in a similar way to radar, working on changes in the reflected radio waves. They are especially effective in Large areas such as Warehouses monitoring any changes in the return waves and responding immediately
