Bộ cảm biến radar không dây Hb 100 10.525ghz Xd chuyên dụng

Hb10 Microwave Placement is Used by Doppler Radar (D/pleasant madness) Microwave Movement of Mustard Designed by Principle, mainly used in automatic door control、 safety Petty System、 automatic Saile Control System for ATMs、 train automatic signal machine, etc. Hb100 is the standard 10.525 berry martyr of z microwave Doppler radar, this form of sterling has the following compared with other sterility.: 1、 non Contact Persons 2、 no temperature、 humidity、 noise、 air stream、 dust、 effects of light etc., suitable for the mosaic environment 3、 strong anti shooting capacity 4、 small Power, not harmful to the structure of the gnawing 5、 remote: Range beyond 20 meters.



The Doppler Principle: The Doppler theory is based on time, the wave is reflected when it is touched in the march, the reflection of the martyrdom will change with the touch of the moving state. If the gnaw touches the position of the grease is fixed., then the martyrdom of the reflected wave should be equal to the emission wave. If it moves in the direction of the launch, the reflected waves will be maddened, getting a grease reflection wave will increase Conversely, the reflection of the wave will reduce the mileage.



The microwave carnage device designed according to the Doppler principle is from the fet medium dro microwaves oscillation source (10.525 Petrelsz)、 power Distributor、 launch antenna、 getting a Better Antenna、 mixer、 composition of inspectors, etc. (Figure 2)。 Launch antennas directed outwardly to launch microwaves, reflected when you meet with a gun, reflected waves are mishandled by antennas, then mix with the oscillator, mixed、 the low frequency signal after checking reflects the speed of the petal movement
