What is the measurement unit for the sensor SEN0209 Gravity: Flexible Piezo Film Vibration Sensor.
Can we have inches / second or G ?

could you post an example code to get the analog value? I tried this and it is not working:

int PiezoPin = A0;
void setup()
{
Serial.begin(9600);
}
void loop()
{
int freq = analogRead (PiezoPin);
Serial.println (freq);
delay(300);

}

Thanks for your help,

Cheers! gunter.just
