Feature Highlights: 1. Simulated Vibration Sensing – Uses a piezoelectric ceramic plate to detect vibrations and convert them into electrical signals, enabling responsive vibration-based interaction. 2. Easy Integration – Connects directly to analog port A0 of your controller. Different vibration levels produce varying output values, which can be read via serial communication. 3. Adjustable Sensitivity – Features a built-in potentiometer to fine-tune sensitivity. Turn left for lower sensitivity, right for higher—perfect for detecting light taps or stronger shakes. 4. High Sensitivity & Versatility – Responds to subtle vibrations like blowing or gentle tapping, making it ideal for interactive projects such as electronic drums, motion triggers, or alarm systems. 5. Ready-to-Use Module – Includes a dedicated sensor expansion board for stable performance, even when analog port signals are weak. No complex setup required. Product Details: This piezoelectric vibration sensor module transforms physical vibrations into readable electrical signals. It works by generating a voltage when the ceramic plate vibrates, which is then processed through the analog port for interactive applications. Simply connect it to your controller’s A0 pin, monitor real-time output via serial data, and adjust sensitivity with the potentiometer to match your project’s needs. Ideal for DIY electronics, educational kits, and interactive installations.
