HB100 Doppler Radar Microwave Motion Sensor
1 x HB100 Doppler Radar Microwave Motion Sensor Module
HB100 Microwave Sensor Module 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.
HB100 is the standard 10.525GHz microwave Doppler radar detector, the detection method compared with other detection methods have the following advantages:
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, which will increase the frequency of the reflected wave; otherwise the reflected wave’s frequency decrease.
1. There may be slight size deviations due to manual measurement, different measuring methods and tools.
2. The picture may not reflect the actual colour of the item because of different photographing light, angle and display monitor.
In this video, Bert explains the inner workings of an HB100 and you can use your PC’s sound card to gain some interesting measurement.
