Piezoelectric vibration tapping sensor module Key benefits - Provides a direct, voltage-based measure of vibration intensity: the higher the vibration, the higher the output voltage. Sensitivity is adjustable via a potentiometer to suit different environments and signal levels. - Flexible outputs for easy integration: an analog voltage output (ADO) proportional to vibration amplitude and a TTL digital output (DO) that indicates a high level when vibration is detected. - Easy to use with sensor expansion boards and common microcontroller projects: supports both analog and digital interfaces for versatile control schemes. - Suitable for interactive vibration work and measurement tasks with straightforward readouts and simple signal conditioning. What it is and how it works - A piezoelectric vibration tapping sensor module. The analog output voltage scales with vibration intensity, and the sensitivity can be adjusted using the potentiometer. Outputs - Analog output (ADO): voltage proportional to vibration amplitude, adjustable via potentiometer. - Digital output (DO): TTL high level output with indication for detected vibration. Interoperability and usage notes - Can be used in combination with special sensor expansion boards; the analog signal may require conditioning for some applications, while the digital output provides a clean trigger signal for simple control. - The module supports interactive vibration-related projects by providing both analog and digital interfaces for readout and actuation. Applications - Machinery condition monitoring and fault detection (bearing, mounting, or component vibration). - Robotic sensing and interactive installations requiring vibration feedback or tap detection. - Educational experiments and DIY projects to explore piezoelectric sensing, signal conditioning, and microcontroller interfacing.
