Introduction

This vibration sensor module(SW-420) is based on a vibration sensor SW-420, it is also a normal off switch on or off based on the environment, it keeps on when there’s no vibration, and the module output logic low, the green led on, when detect the vibration, the switch off, and the module output logic high, the green led off. There’s a variable resistance designed for set the threshold also means the accuracy.
