The DFRobot Vibration Sensor buffers a piezoelectric transducer that responds to strain changes by generating a measurable output voltage change which is propotional with the strength of vibration.So you can know the extent of vibration. Different from digital vibration sensor that only accounts times, this analog one can tell extent of vabiration.
