Vibration sensor module with adjustable sensitivity and LED output, designed for precise detection and simple integration with controllers. Key benefits Tunable sensitivity: A builtin potentiometer lets you finely adjust responsiveness so the sensor reliably detects light mouth blows or firmer hand taps while filtering out unwanted background vibration. Visual feedback: Onboard LED indicates output activity, making setup and troubleshooting straightforward without additional tools. Easy integration: Provides a TTL level output and connects to controller analog terminals. Output values can be observed directly to implement vibrationdriven interactions quickly. Flexible use: Accurate detection across a range of vibration intensities makes the module suitable for interactive projects, musical triggers, robotics, and prototypes. Main features Adjustable sensitivity via potentiometer for precise threshold control. LED indication for output signals to speed up debugging and calibration. TTL level output compatible with controller analog terminals for straightforward wiring. Ability to connect external LED lights to extend visual feedback. How it solves common problems Reduces false triggers by letting you set the exact detection threshold for your environment. Speeds development by providing a visible output indicator so you can confirm behavior during calibration. Simplifies wiring and integration with controllers that read analog values or TTL signals. Typical applications Interactive installations and exhibits that respond to taps or blows to trigger lights, sounds, or animations. DIY electronic instruments and percussion triggers that detect strike intensity for expressive control. Robotics and security prototypes where impact or vibration events must be detected and relayed to a controller. Compatibility and performance notes Outputs TTL level signals and is intended for use with controller analog terminals where output values can be monitored. Potentiometer adjustment enables detection of a wide range of vibration levels for different use cases. External LEDs can be connected for enhanced visual indication of events. This sensor module is designed for projects that require reliable, adjustable vibration detection and straightforward controller integration.
