Piezo Element 27mm Piezoelectric

This basic Piezo Element measures 27mm accross and is a great vibration sensor. Attach the round disc to the object that will be knocked on such as a door and measure the voltage across the two wires. Piezo elements can also produce sound when a voltage is applied across them. They convert between electricity and vibration in both ways; Vibration applied at the round end can be detected as a voltage across the wire leads and inversely, voltage applied across the wire leads causes the round end to vibrate.
