- This Ceramic Piezo Vibration Piece Sensor buffers a piezoelectric transducer that responds to strain changes by generating a measurable output voltage change which is proportional 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 vibration.
- When the piezoelectric ceramic shocking will generate an electrical signal, controller analog port can be perceived slight vibration signals, also can be realized with vibration interactions related works, such as electronic drums.
