A simple piezo element that can be used as both a sensor and a small audio transducer. When flexed or tapped, it generates a voltage that can be read by a microcontroller, making it ideal for knock and vibration detection projects.

Connect the output to an analog input on your Arduino or other microcontroller to detect taps, knocks, and vibrations. It can also be driven as a basic buzzer for simple audio feedback.

Key Features
