Piezoelectric sensor module based on piezoelectric ceramic chip analog vibration makes use of the anti-transformation process of piezoelectric ceramic making the electric signals vibrate. Different from digital vibration sensor that only accounts times, this analog one can tell extent of vibration. Analog ceramic piezo vibration sensor module working voltage: 3.3V or 5V; Working current: 1mA; Interface type: Analog Output. 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. Piezo 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. Please connect analog voltage ceramic vibration sensor to the controller's analog port A0 in accordance with the procedure, then observe the output value of serial port when the vibration degree is different, it can realize interactive works related to the vibration.
