Piezoelectric ceramic vibration sensor module working voltage: 3.3V or 5V; Working current: 1mA. Analog ceramic vibration sensor module 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. 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. 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. 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. Working voltage: 3.3V or 5V
Operating current: <1mA
Operating temperature range: -10℃ ~ +70℃
Interface type: analog signal output
Pin definition: S signal output, + power supply (VCC), -ground (GND)
Input: The positive pole of a piezoelectric ceramic plate
Gnd: The negative pole of piezoelectric ceramic plates
Port S is connected to the controller's analog input pin.
5V and GND are respectively connected to +5V and GND of the power supply.
Input and Gnd are already connected with the piezoelectric ceramics' positive and negative.

Sample Code
void setup()
{Serial.begin(9600); //Open the serial to set the baud rate for 9600bps}
void loop()
{int val; val=analogRead(0); //Connect the analog piezoelectric
ceramic vibration sensor to analog interface 0
Serial.print("Vibration is ");
Serial.println(val,DEC);//Print the analog value read via serial port delay(100); }
Result wiring as the diagram and burning the code, after power-on, open the serial monitor, then set the baud rate for 9600 and vibrate ceramic chip,

Package include:
6 x Piezo Ceramic Vibration Sensor
