SW-420 vibration module, operates on 3.3V to 5V. The sensor uses LM393 comparator to detect the vibration over a threshold point and provide digital data, Logic Low or Logic High, 0 or 1. During normal operation, the sensor provides Logic Low and when the vibration is detected, the sensor provides Logic High. Two onboard LED indicators, one for the Power state and other for the sensor's output. Potentiometer to adjust sensitivity. Pc board is 32 x 14 x 7mm. Three pins on 0.1" centers.
