35mm Piezo Electric Sensor 72mm Green Paper Adhesive Tape Model 68KTYZ Operating Voltage 220VA piezoelectric sensor or element is a device that uses the piezoelectric effect to convert voltage to vibration and vibration to voltage. This is a piezoelectric disc that picks up sound from musical instruments and other devices. Because it produces analogue output, you can connect it to a comparator circuit to produce digital output, or you can connect it directly to the microcontroller you're using. It is small and reliable enough to handle rough
