Large Enclosed Piezo Element w/Wires

This large 30mm diameter piezo element is nicely enclosed with mounting holes so you can mount it easily on something.

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.
