The SW-420 sensor module produce logic states depending on vibration and external force applied on it.
When there is no vibration this module gives logic LOW output and when it feels vibration the output goes to logic HIGH.
The working voltage of this module is between 3.3v to 5v DC and has a potentiometer to set sensitivity.
