Key benefits sensitivity lets you match sensor response to your application, from gentle mouth blows to firm taps. TTL level output with LED indication gives a clear, visible digital signal that is easy to read and integrate. Piezoelectric ceramic transducer provides reliable vibration generation and sensing for interactive electronic projects. What this product does and why you need it Converts mechanical vibration into a TTL digital output. The stronger the vibration, the higher the output voltage, enabling proportional response and easy triggering of digital circuits. Adjustable output sensitivity via a builtin potentiometer allows you to fine tune detection thresholds, reducing false triggers and improving responsiveness for different use cases. Onboard LED provides an immediate visual indication when the sensor is active, simplifying testing and debugging. Key features Output type: TTL level digital output suitable for direct connection to digital inputs. Visual indicator: LED that lights when vibration is detected. Sensing element: piezoelectric ceramic for both vibration generation and detection. Sensitivity control: adjustable potentiometer for precise tuning. Response: sensitive enough to detect light inputs such as mouth blows or hand taps. Integration: compact form factor for straightforward mounting and wiring into circuits. Compatibility and performance Works with microcontrollers and digital input boards that accept TTL logic levels, making it easy to integrate with common development platforms and control systems. Designed for lowlatency detection and clear digital signaling rather than analog measurement, simplifying use in trigger and interactive applications. Typical applications Electronic percussion and musical interfaces: use as a trigger for electronic drum pads, foot controllers, or contactbased sound modules. Interactive installations and DIY projects: add responsive touch or vibration control to art pieces, props, or interactive displays. Educational and prototyping use: integrate into microcontroller lessons or prototype systems where simple, visible vibration detection is required. What makes it stand out Combines piezoelectric sensing with an adjustable sensitivity control and a TTL output to provide a reliable, easytointegrate trigger sensor. LED feedback simplifies setup and troubleshooting without extra tools. sensitivity and tuning range let you deploy the sensor in a variety of environments and applications without changing hardware. Includes Vibration sensor module with piezoelectric element, potentiometer for sensitivity adjustment, TTL output pin, and LED indicator. Notes for integration Connect the TTL output to a digital input that accepts logic level signals. Test sensitivity with small taps and adjust the potentiometer to set the desired trigger threshold. Avoid exposure to excessive mechanical shock beyond intended use to preserve longterm performance.
