Function: Interactive vibration sensor module that connects to analog terminals to trigger electronic drum interactions with realtime response to vibration intensity. Output: TTL level signals capable of driving loads up to 1 A; can switch external LED lights and other TTLcompatible devices. Sensing element: sensitivity piezoelectric ceramic sensor for precise, fast vibration detection. Sensitivity control: Onboard potentiometer to finetune amplitude for detecting mouth blows, taps, or knocks. Compatibility and performance: Designed for microcontroller analog inputs; reliable signal with responsive performance in a compact package. Use scenarios: Electronic drum triggers and percussion controllers for DIY setups. LED lighting effects synchronized to claps, taps, or vocal cues in stage or art installations. Educational DIY experiments to explore vibration sensing and simple controller prototyping.
