Information

Microwave sensor is a device that uses microwave characteristics to detect some physical quantities. Including the presence of sensing objects, moving speed, distance, angle and other information.

Access control Microwave sensor For sale
The manufacturer of the Microwave sensor tells you that the microwave emitted by the transmitting antenna will be absorbed or reflected when it encounters the object under test, causing the power to change. If the receiving antenna is used to receive the microwave that passes through or is reflected by the measured object, and converts it into an electrical signal, which is then processed by the measurement circuit, microwave detection is realized.
Microwave sensor is mainly composed of microwave oscillator and microwave antenna. A microwave oscillator is a device that generates microwaves. The components that make up the microwave oscillator are klystrons, magnetrons or some solid components. The manufacturer of the Microwave sensor tells you that the oscillating signal generated by the microwave oscillator needs to be transmitted by a waveguide and emitted through an antenna. The manufacturer of the Microwave sensor tells you that in order to make the emitted microwave have consistent directivity, the antenna should have a special structure and shape.
