Description:
1, Size: 37mmX45mmX8mm
2, the main chip: HB100
3, work voltage: DC 5V
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.
