The SW-420 Vibration Sensor Module detects shaking, knocking and vibration and outputs a clean digital signal to your Arduino. Built around the SW-420 spring switch and an LM393 comparator with an on-board potentiometer, it is a simple, reliable way to add tamper and impact detection to alarms and security projects.
