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 Pin Definition Tutorial Connection diagram 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.
