X-Band Doppler Motion Detector Microwave Sensor Module
The Microwave Solutions PD-V10-G5 Motion Detector Unit is a miniature X-Band microwave transceiver that utilises the Doppler shift phenomenon to "sense" motion.
The unit, housed in a metal can, features a dielectric resonator stabilised oscillator, which provides stable operation over a broad temperature range in either CW or low duty cycle pulse mode and an integrated homodyne receiver for enhanced sensitivity and reliability.
This module family is available with either a +5v or +3v supply voltage.
The basic principle of operation consists of detecting the frequency shift between a transmitted and a received signal reflected back from a moving object within the field of view of the unit.
The unit produces a low level output signal which can be amplified and processed to provide an audible or visual alarm signal and employs low cost surface mount manufacturing techniques which are field proven as being rugged and reliable.
The strength of the sensor's output （detection range）depends on the Signal to Noise Ratio.
Higher or lower than the nominal operating temperature, the sensor can also work, but the performance will be reduced.
To avoid damage to the devices, care should be exercised during handling. Proper Electrostatic Discharge (ESD) precautions should be observed at all stages of storage, handling, assembly, and testing.
