Introduction to microwave sensors
Nov 08, 2021
Microwave sensor is also called radar sensor. Microwave sensor switch is an active sensor. The sensor emits high-frequency electromagnetic waves and receives their echo. This sensor detects changes in the echo, even small movements within the detection range, and then triggers commands . The microwave induction switch is a new type of dead-angle induction. Based on the principle of Doppler radar, its planar antenna emits extremely low-power electromagnetic waves and receives reflected echoes. It can effectively suppress the interference of high-order harmonics and other clutter, has high sensitivity, strong reliability, safety and convenience, and intelligent energy saving. It is a new and practical energy-saving product. If a change in the reflection frequency of the sensing area is detected, the sensor triggers an action, and the output signal turns on or off the load as needed.
