What’s the simplest way to check vibration with Arduino? Use a vibration sensor from DFRobot. You can directly plug it into our IO Expansion Shield V7. Just vibrate this sensor, and Arduino can receive a digital signal. It’s easy to account for and program in Arduino.

Despite its simplicity, you can make full use of it with creative thinking, like step counting, Crash warning lights and so on.
