About this item

The Piezo Vibration Sensor – Large is a high-sensitivity sensor designed to detect vibrations, impacts, and motion in a wide range of applications. Utilizing a piezoelectric element, it converts mechanical vibrations into electrical signals, making it ideal for projects involving movement detection, knock sensing, impact monitoring, or security systems. Its larger form factor provides increased sensitivity and output signal strength compared to smaller variants, enabling detection of even subtle or low-frequency vibrations. This sensor is passive, requiring no external power supply to function, and outputs a voltage signal that can be directly read by microcontrollers such as Arduino, Raspberry Pi, or other embedded platforms. Its flexible construction allows it to be attached to flat or curved surfaces, and it can sense vibrations in multiple directions. It’s widely used in touch interfaces, smart alarms, musical instruments, and industrial machinery monitoring. Due to its simplicity, reliability, and cost-effectiveness, the Piezo Vibration Sensor – Large is a popular choice for hobbyists, researchers, and engineers looking to integrate basic motion or impact detection into their designs. With minimal circuitry required for signal conditioning, it's easy to integrate into analog or digital systems.
