This module has been structured as an option in contrast to the PIR movement finders regularly utilized in thief alarms. Rather than detecting changes in infrared radio discharged by a moving individual this sensor utilizes a microwave Doppler radar to distinguish moving items. It has an affectability scope of ~7 meters. At the point when set off its trigger output pin will change from (LOW) 0V to high (3.3V) for ~ 2 to 3 seconds before coming back to its inactive LOW state
