An analog vibration sensor built on a piezoelectric ceramic sheet. It detects mechanical vibration and converts it into an electrical signal, producing an analog voltage proportional to the vibration amplitude. Designed to work with standard sensor expansion boards, it provides an analog output that can be read by common microcontroller analog inputs. The sensor is compact and easy to integrate into DIY projects. Key benefits sensitivity with adjustable gain via a small potentiometer (turn clockwise to increase sensitivity) Direct analog output suitable for precise vibration measurement Simple, compact form factor that fits with existing boards and firmware Performance notes Output voltage scales with vibration intensity Tunable to respond to light taps, stronger taps, or breathlike stimuli depending on the setting Use scenarios Electronic drum pads, percussion controllers, or haptic musical interfaces Interactive art installations and gesturetriggered effects Basic vibration monitoring for small motors, appliances, or structures in DIY projects This sensor provides a straightforward, reliable vibration sensing solution with adjustable gain, compact size, and readytoread analog output.
