HB100 microwave modules is the use of Doppler radar (Doppler Radar) design principles of the microwave moving object detector, mainly used in automatic door control switch, security systems, ATM ATMs automatic recording control system, automatic train signals, etc. places. HB100 10.525GHz standard microwave Doppler radar detector, the detection method in comparison with other detection method has the following advantages: 1, non-contact probe; two, independent of temperature, humidity, noise, air, dust, light other effects, suitable for harsh environments; 3, anti-RF interference ability; 4, the output power is small, constitute a hazard to humans; 5, distance: detection range over 20 meters.

Doppler principle Introduction: Doppler theory based on time, when radio waves hit an object in the process of moving the wave is reflected, the frequency of the reflected wave will move across the state with an object is changed. If the touch position of the object radio wave is fixed, the frequency of the reflected wave and the transmitted wave frequency should be equal. If the object moves in the direction of transmission, the reflected wave will be compressed, that will increase the frequency of the reflected wave; conversely the frequency of the wave will be reflected decreases.

According to the principle of the Doppler microwave detectors designed by the FET source media DRO microwave oscillation (10.525GHz), power splitter, transmitting antenna, receiving antenna, mixers, detectors and other circuit (Figure 2). A microwave transmission antenna transmitting outwardly directed, when the object is encountered and the reflected wave is received by the receiving antenna, a mixer and then to the oscillation mixed at low-frequency signal after detection of the reaction speed of moving objects

4,HB100 is the use of microwave Doppler radar module (Doppler Radar) design principles of the microwave detector moving objects, mainly used in automatic door control switches, security systems, ATM ATM automated video control systems, automatic train signal, etc. place. HB100 is the standard 10.525GHz microwave Doppler radar detector, the detection method compared with other detection methods have the following advantages: 1, non-contact detection; 2, independent of temperature, humidity, noise, air, dust, light other effects, suitable for harsh environments; 3, anti-RF interference ability; 4, the output power is small, constitute a hazard to humans; 5, distance: more than 20 meters detection range.

5,Doppler Principle: Doppler theory based on time, when radio waves encounter an object in the moving process will be reflected when the waves, the frequency of the reflected wave will hit the object with the movement to change state. If the radio waves encounter an object position is fixed, then the reflected wave frequency and transmitting frequency waves should be equal. If the object moves toward the launch, then the reflected waves will be compressed, that will increase the frequency of the reflected wave; otherwise the reflected wave's frequency decreases.
