Product Description
Doppler radar is the Doppler effects radar positioning, velocity, ranging work. Is the so-called Doppler effect, when the vibration source and the observer of the sound, light, radio waves and other relative movement of the relative velocity V, the frequency emitted by the viewer received the vibration frequency of the vibration source is different. Austrian scientists Doppler first discovered this phenomenon, it is called the Doppler effect. Formed by the frequency change by Doppler effects is called the Doppler frequency shift, which is proportional to the relative velocity V is inversely proportional with the frequency of the vibration.
Used in Microwave Sensor Switch:
Microwave switch for active sensors, sensor emitting high-frequency electromagnetic waves (5.8GHz) and receives their echo within the echo of this sensor detects changes even the tiny moving within its detection range. The microprocessor then trigger "point lighting" instruction. Signals through a door, a glass plate, and the thin walls are likely to be detected.
