Description this large (30mm diameter) piezo element is nicely enclosed with mounting holes so you can attach easily. Piezo elements convert vibration to voltage or voltage to vibration. That means you can use this as a buzzer for making beeps, tones and alerts and you can use it as a sensor, to detect fast movements like knocks. You can also use it under a drum pad to make a drum/crash sensorits rated for up to 12vpp use but you can also use 3 or 5v square waves and its plenty loud.
