Microwave Doppler radar sensor HB100

This HB100 Miniature Microwave Motion Sensor is an X-Band Bi-Static Doppler transceiver module. The built-in Dielectric Resonator Oscillator (DRO) and a pair of microstrip patch antenna arrays make it ideal for OEM use in motion detection equipment. This module is ideally suited for reducing false alarms in intruder detectors when used in conjunction with a passive infrared (PIR) sensor. It can also be used for automatic door opening and vehicle speed detection.
