HB100 Microwave Doppler Nirkabel Radar Detector Probe Sensor 10.525GHz

The HB100 microwave module is a microwave moving object detector designed by Doppler Radar principle. It is mainly used in automatic door control switch, safety protection system, automatic recording control system of ATM automatic teller machine, automatic train signal, etc. place. HB100 is a standard 10.525GHz microwave Doppler radar detector. This detection method has the following advantages compared with other detection methods: 1. Non-contact detection; 2. Free from temperature, humidity, noise, airflow, dust, light. Such as impact, suitable for harsh environments; 3 , strong anti-radio interference capability; 4, low output power, no harm to the human body; 5, long distance: detection range of more than 20 meters.

Introduction to the Doppler principle: The Doppler theory is time-based. When a radio wave hits an object during traveling, the wave is reflected. The frequency of the reflected wave changes with the moving state of the object. If the position of the object hit by the radio wave is fixed, the frequency of the reflected wave and the frequency of the transmitted wave should be equal. If the object moves in the direction of the emission, the reflected wave will be compressed, that is, the frequency of the reflected wave will increase; otherwise, the frequency of the reflected wave will decrease.
