Piezo Vibration Sensor


Product Description

The Minisense 100 is a low-cost cantilever-type vibration sensor loaded by a mass to offer high sensitivity at low frequencies. Useful for detecting vibration and ‘tap’ inputs from a user. A small AC and large voltage (up to +/-90V) is created when the film moves back an forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact sensing or a flexible switch.

Comes with solder pins that allows for vertical mounting.


  • Flexible PVDF Piezo Polymer Film
  • Wide dynamic range
  • Laminated for higher voltage output
  • Breadboard friendly leads





//defines the pin connections int GroundPin= 0; int sensePin= 1; int LEDPin= 13;

//defines normal and threshold voltage levels int threshold= 500;

//sets GroundPin and LEDPin as output pins, with GroundPin being set to LOW void setup() { Serial.begin(9600); pinMode(GroundPin, OUTPUT); digitalWrite(GroundPin, LOW); pinMode(LEDPin, OUTPUT); }

//if the reading is higher than the threshold value, then the LED is turned on void loop() { int reading= analogRead(sensePin); Serial.println(reading); if (reading > threshold) { digitalWrite(LEDPin, HIGH); delay(1000); digitalWrite(LEDPin, LOW); } }
