Seeed Studio Studio Grove Piezo Vibration Sensor - Module Only

The module is designed to operate at the standard Grove system voltages, which are typically 3.3V or 5V DC. The exact voltage is supplied by the Grove base shield or microcontroller board it is connected to. Always ensure your host board provides a compatible voltage.

You need a Grove Base Shield V2 (or compatible) for Arduino. Plug the sensor into any digital port (D2-D8) on the base shield. The shield then mounts onto the Arduino Uno, providing both power and a digital communication line. No external wiring or pull-up resistors are required.

Yes, the module features an adjustable sensitivity potentiometer. By turning this potentiometer, you can set the threshold at which the onboard comparator triggers the digital output from LOW to HIGH, allowing you to fine-tune it for different vibration intensities.

The sensor outputs a digital logic signal. When vibration exceeds the set sensitivity threshold, the output pin goes HIGH (typically at the operating voltage, e.g., 3.3V or 5V). When no significant vibration is detected, the output remains LOW (0V). This signal can be read directly by a microcontroller's digital input pin.

While it has an extremely wide dynamic range, its primary function is impact detection and vibration event triggering via a digital output. For precise, continuous frequency analysis, you would typically use an analog piezoelectric sensor paired with an ADC and signal processing, rather than this digital-output module.
