This Ceramic Piezo Vibration Sensor features a piezoelectric transducer that generates a measurable output voltage in response to strain changes, providing an analog signal proportional to the intensity of vibration. Unlike digital vibration sensors that only count events, this analog sensor allows you to measure the degree of vibration. It operates based on the piezoelectric ceramic chip's ability to convert mechanical stress into electrical signals through the inverse piezoelectric effect. When subjected to vibration or shock, the sensor produces an electrical signal that can be read by a microcontroller's analog input, enabling detection of subtle vibrations. This makes it suitable for vibration-based interaction projects, such as electronic drums or impact detection systems.
