Analog_Piezo_Disk_Vibration_Sensor_(SKU_DFR0052)

Analog Piezo Disk Vibration Sensor (SKU:DFR0052)

Introduction

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.

Specification


- Power supply: Not necessary to power the module

Interface: Analog
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 pressure is applied not to the piezoelectric ceramics, the analog output of 0; when pressure is applied to the piezoelectric ceramics, the analog output will send the change, but as the pressure increases.
