The Arduino vibration sensor module is based on vibration switch component which can detect the weak vibration signals. The sensor can work for vibration-related modules. The conductive pin will make an instant turn-on (ON) state when touched by the outside force to achieve the proper vibration force, or an appropriate speed from the (partial) energy. No direction, any angle may burst. The switch is suitable for small-current circuit (secondary circuit) or (IC) of the trigger. At room temperature and normal use the next switch service life is up to 10 million times (times/1sec). VCC - 5V;GND - GND;S   - Digital pin3;
