Introduction
A simple vibration sensor dependent on a piezoelectric ceramic sheet is a converse change process that utilizes piezoelectric ceramics to create vibration. So, when the piezoelectric ceramic piece vibrates, it produced an electrical signal.
An Overview of Vibration Sensor
An analog vibration sensor based on a piezoelectric ceramic sheet. Piezoelectric ceramics are materials that convert mechanical energy and electrical energy. Piezoelectric ceramics have dielectric properties, and flexibility, and have been broadly utilized in different fields like medical imaging, etc
Working Principle
They based their working principle on vibration. The greater the vibration, the larger the output voltage. The potentiometer can adjust the sensitivity of the vibration amplitude. We can adjust the high-sensitivity output to respond with a mouth blow or a tap with a hand.
