Can piezo buzzers can detect vibration?

Yes, piezo buzzers can detect vibration. In fact, detecting vibration is one of the primary applications of piezo buzzers. When a piezo buzzer is subjected to a mechanical vibration, it generates an electrical signal proportional to the amplitude of the vibration. This signal can then be amplified and used to trigger other devices or to provide feedback.

Piezo buzzers work based on the piezoelectric effect, which is the ability of certain materials to generate an electrical charge in response to mechanical stress. The piezo element inside the buzzer is made of such a material, and when subjected to a vibration, it produces an electrical charge.

In addition to detecting vibration, piezo buzzers are commonly used for generating sound in various applications such as alarms, timers, and musical instruments.
