Description
This module has been designed as an alternative to the PIR motion detectors commonly used in burglar alarms. Instead of sensing changes in infrared light emitted by a moving person, this sensor uses a microwave Doppler radar to detect moving objects. It has a sensitivity range of ~7 meters. When triggered its trigger output pin will switch from (LOW) 0V to high (3.3V) for ~ 2 to 3 seconds before returning to its idle LOW state.
