The Ground and the 5V pin are used to power up the Arduino whereas the A5 pin is used to get the data from the vibration sensor. The circuit is constructed where the SW-420 module and LED are ...

As you might notice, the core part of the SW-420 vibration sensor module is an omni-sensing vibration/tilt switch that has a part number SW-420. Looking at some details of this single-roller type ...

The SW-420 Vibration Sensor will detect large disturbances and send the data to the Arduino. The occurrence and strength(Intensity) of the vibrations will be ...
