Micro wave motion detector

DRO-571 MICROWAVE DOPPLER TRANSCEIVER

DESCRIPTION:

The DRO-571 MICROWAVE DOPPLER TRANSCEIVER is a low cost sensor designed for any speed measurement or motion sensing application. It provides an audio output signal which frequency is proportional to the velocity of an object moving toward to away from the antenna.

Typical applications:

doppler Radar Systems.
Speed and Rotation Measurement systems.
Intrusion Alarms for Vehicle and Room.
Traffic Signal Actuators.
Automatic Door Openers
Obstruction Warning Systems.
Other Moving Detector System
Process Industry Control.
Contactless Vibration Measurement
Collision Avoidance
Transmitters.
Marine Radar
Lighting Control.

Application notes:

The module is supplied with shorting links across the mixers to protect them from the effects of static charge. These shorting links should be left in position until after all wiring assembly work is complete.
The detection range will depend on the size and reflectivity of the target, the signal to noise ratio required and antenna gain.
The transmitter frequency is factory preset. The required operating frequency must be specified when ordering
Doppler shife frequency at 10.525GHZ is 31 Hz/mph
