Overview

Need a simple way to detect vibration in an Arduino or Raspberry Pi project? DFRobot’s Gravity Digital Vibration Sensor outputs a digital signal when it senses shaking, knocking, impact, or other vibration events, making it straightforward to build trigger-based projects.

The module uses a Gravity 3-pin interface and works with 3.3V to 5V systems, so it can be paired with common platforms such as Arduino, Raspberry Pi, ESP32, and micro:bit. It is designed for easy wiring and simple code integration.

This sensor is intended for basic vibration event detection. It can tell you when a vibration occurs, but it does not measure vibration strength, frequency, acceleration, or continuous waveforms.

• Digital output for event detection
• Detects shaking, knocking, impact, and vibration
• 3.3V to 5V operating range
• Gravity 3-pin plug-and-play connection
• Compact 22 × 30 mm size
• Suitable for alarms, triggers, and anti-tamper projects

Specifications should be verified on the official manufacturer page.
