SW-420 Vibration Sensor Module

SW-420 is a vibration sensor module, based on the SW-420 vibration sensor and LM393 comparator to detect the vibration beyond the threshold. The threshold can be adjusted using an on-board potentiometer. During no vibration, the sensor provides logic LOW, and when vibration is detected the sensor provides logic HIGH.
