Introduction

The DFRobot Vibration Sensor buffers a piezoelectric transducer that responds to strain changes by

generating a measurable output voltage change wh ich is propotional with the strength of vibration.

Specification

Power supply: Not necessary to

power the module

Interface: Analog

Current: less than 1mA

Weight: 10g

Pin Definition

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.
