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 and 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 allow for vertical mounting.

Features:

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

Code

int GroundPin= 0;
int sensePin= 1;
int LEDPin= 13;
int threshold= 500;

void setup(){
Serial.begin(9600);
pinMode(GroundPin, OUTPUT);
digitalWrite(GroundPin, LOW);
pinMode(LEDPin, OUTPUT);
}

void loop(){
int reading= analogRead(sensePin);
Serial.println(reading);
if (reading > threshold){ 
digitalWrite(LEDPin, HIGH);
delay(1000);
digitalWrite(LEDPin, LOW);
}
}
