Learn — SW-420

The SW-420 Vibration Sensor Module is a useful module for detecting vibrations over a threshold point and provide digital data, 0 or 1. It uses an LM393 comparator to detect and it can work from 3.3V to 5V.  In this article, we'll talk about how to wire and set up the module for operation with an Arduino Board.  Wiring This module can work from 3.3V to 5V. In this project, we will use 5V to power the module. During normal operation, the sensor provides Logic Low and when the vibration is detected, the sensor provides Logic High. There are several...
