## Description

10.525GHz microwave Doppler radar module for detecting object movement at over 20 m, ideal for automation, security and industrial projects. It operates at 5VDC, has low consumption, integrated antenna with 8dBi gain and wide detection angle, provides stable Doppler signal for processing with external amplifier.
Doppler type radar sensor module.
The HB 100 module uses 10.525GHz microwave Doppler type waves to detect moving objects. This module has the advantage of detecting the motion of any object (not necessarily people) at a distance of over 20 meters.
The operating principle is based on radio waves that reach the object and reflect back to the module. In case of movement towards it, the radio waves compress (increasing their frequency), when moving away from it, the radio waves expand (decreasing the frequency), and in the case of stationary objects, the waves do not change, their frequency remaining unaltered.
It is recommended to use a signal amplifier together with this module.
