Vibration Measurement Device is a device that can detect vibration and analyze the vibration frequency and amplitude. By using Arduino microcontroller and accelerometer sensor, the device is able to detect vibration and plot both time-domain graph and frequency-domain graph of the vibration detected.
Objective
The objective of this project is to build a device that can detect and measure vibration. The device will transform the raw data of time-domain plot into frequency-domain plot which is used in vibration analysis.
Methodology
Arduino IDE is used in the coding of Arduino Nano microcontroller. The device consists of Arduino Nano and ADXL335 accelerometer. FFT library is included in the coding of Arduino microcontroller and the raw data of reading from accelerometer is transformed directly into frequency-domain plot. Validation of the device is performed with static test that shows no vibration, shaking test that shows random vibration and fix-frequency test that shows a specific frequency played by speaker.
