Product description

Welcome to our shop for shopping.
HB100 is the use of microwave Doppler radar module (Doppler radar) principles of microwave detector objects design in motion, mainly used in door automatic control switches, security systems, ATM ATM automated video control systems, automatic train, etc. HB100 is the standard 10,525 ghz microwave radar Doppler detector, the detection method compared to other detection methods has the following advantages: 1, detection of non-contact; 2, independent of temperature, humidity, noise, dust, air, other light effects, suitable for harsh environments; 3, anti-interference RF capability; 4, The output power is small, to constitute a danger to humans; 5, distance: more than 20 meters detection range.
Doppler principle: Doppler theory based on time, when the radio waves find an object in the process of change 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 in finding an object position is fixed, then the frequency of the reflected wave and transmit 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 frequency decreases.
