Introduction

The DFRobot Vibration Sensor buffers a piezoelectric transducer that responds to strain changes by generating a measurable output voltage change. Therefore the volatage is propotional with the strength of vibration.

Specification

Power supply: Not necessary to power the module
Interface: Analog
Supply Voltage: 3.3V to 5V
Current: less than 1mA
Weight: 10g

Sample Code

void setup()
{
  Serial.begin(9600); //
}
void loop()
{
      int val;
      val=analogRead(0);//Connect the sensor to analog pin 0
      Serial.println(val,DEC);//
      delay(100);
}

Result

When no pressure is applied to the piezoelectric ceramics, the analog output is 0; when pressure is applied to the piezoelectric ceramics, the analog output will being correlated to the amount of pressure.
