Piezoelectric Plate 28mm

Piezoelectric Plate 28mm (1 pc)

The 28mm Piezoelectric Plate is a compact, dual-function component designed to work as both a sensor and sound actuator. It converts mechanical vibrations into electrical signals, and also produces sound when supplied with voltage. This makes it ideal for a variety of audio and sensor-based applications.

With a diameter of 28mm, this piezo plate offers a balance between size, sensitivity, and mounting flexibility. You can use it as a knock sensor, vibration detector, or tone generator in DIY electronics, musical toys, alert systems, and embedded circuits.

For sensing applications, the disc produces a voltage when tapped or vibrated. This signal can trigger actions in microcontrollers like Arduino or ESP32. It’s widely used in drum pads, knock detectors, or tap-sensitive switches.

When used as an actuator, it works as a buzzer to emit tones, alarms, or feedback sounds. Simply apply an alternating voltage using a driver or signal generator. The metal disc construction ensures durability and consistent performance over time.

Moreover, the disc is lightweight, easy to mount, and consumes no power while in sensing mode. Because it has no moving parts, it’s both reliable and long-lasting, even in demanding environments.

Sold as 1 piece (1 pc), the 28mm Piezoelectric Plate is perfect for students, makers, and developers building responsive or sound-based electronics.
