    Introduction

    Need a simple way to detect vibration in an Arduino or Raspberry Pi project? This Gravity Digital Vibration Sensor outputs a digital signal when vibration, shaking, knocking, or impact is detected, making it easy to build event-triggered projects with minimal wiring and code.

    With a 3.3V to 5V operating voltage and Gravity 3-pin interface, the sensor can be used with Arduino, Raspberry Pi, ESP32, micro:bit, and other common microcontrollers. It is suitable for vibration alarms, step counting experiments, crash warning lights, anti-tamper detection, object movement monitoring, and interactive input projects.

    This module is designed for simple vibration event detection. It can detect whether a vibration event occurs, but it does not measure vibration strength, vibration frequency, acceleration, or continuous vibration waveforms.


    Key Features

  • Detects vibration, shaking, knocking, and impact events
  • Digital output for simple event detection and easy programming
  • Wide 3.3V to 5V operating voltage for common controllers
  • Gravity 3-pin interface for quick plug-and-play wiring
  • Standard mounting holes for easy installation in projects
  • Compact 22 × 30 mm size for embedded and portable applications
  • Gold-plated PCB surface for improved durability and signal reliability

    • a simple Pedometer device that can count your step
