Piezo Sensor Element 20 mm nut RS-485 EIA/TIAPiezo element is a sensor which is used to detect vibration, in this case, a knock on a door, table, or other solid surface.

Similarly, when you put a voltage across a piezo, it vibrates and creates a tone. Piezos can be used both to play tones and to detect tones. For more information on piezo electric
