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 detection of vibration levels. Built around a piezoelectric ceramic element, it operates on the principle of piezoelectricity, converting mechanical vibrations into electrical signals. When subjected to vibration or shock, the ceramic element produces an electrical signal that can be read through a microcontroller's analog input. This enables detection of subtle vibrations and supports applications such as vibration monitoring and interactive projects like electronic drums. Analog Ceramic Piezo Vibration Sensor Module compatible with 3.3V or 5V systems Operating Voltage: 3.3V or 5V Operating Current: 1mA Interface Type: Analog Output Color: As shown in image Material: Metal Package Includes: 1 x Piezoelectric sensor module Note: The package includes only the items listed above. Other accessories are not included. Due to lighting reflections and display differences, the actual color may vary slightly from the image. Measurement tolerances may vary by +/- 1-3cm.
