Microwave sensor

- Mar 23, 2018 -

As we know, any wave reflection characteristics, meets the obstacle when waves of a certain frequency, there will be a part of the wave is reflected back, if the obstacle is stationary, the wavelength of reflected wave is constant, if the obstacle is to the waves, the reflection wavelength is shorter than the wavelength of waves, if the obstacle is to stay away from the waves in the direction of the movement, the wavelength of reflected wave is longer than the wavelength of waves, the change of wavelength, means that the change of frequency.It is through the change of the reflection wave microwave induction know a movement toward or away from the object.



The Characteristics:

Response speed;Higher sensitivity;Induction range;High security stability;


Microwave sensor
Is not affected by temperature, air flow, the influence of dust and smoke.
