Piezo Sensor Element 15 mm nor the lock tongue is retractedK Piezo element is a sensor which is used to detect vibration, in this case, a knock on a door, table, or other solid surface. A piezo is an electronic device (sensor) that generates a voltage when it's physically deformed by a vibration, sound wave, or mechanical strain. 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
