Turbulence Intensity Analyser
Build a Turbulence Intensity Analyser with Arduino & ADXL345 — Harness FFT to Quantify Wind Turbulence at 200Hz
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
High-fidelity turbulence measurement is the backbone of wind engineering, weather station instrumentation, and environmental field studies. With this kit, you will construct a complete, self-contained instrument that samples an ADXL345 accelerometer mounted on an anemometer post at 200 Hz, performs real‑time Fast Fourier Transform, and logs the turbulence intensity spectrum to a microSD card — replicating the same signal‑processing pipeline used in research‑grade anemometer calibration.
What You'll Build
A portable turbulence intensity analyser that clamps onto any standard anemometer pole and displays live vibration power spectra on a crisp 0.96‑inch OLED. You will solder the sensor board, wire the Arduino Mega 2560, and program the FFT algorithm to convert time‑domain acceleration into frequency‑domain data. The DS3231 RTC ensures every spectrum is time‑stamped, while the microSD module stores days of continuous recordings. Whether you are validating a wind‑resource map or preparing a Smart India Hackathon demo, you will leave with a field‑ready device that quantifies turbulence with scientific rigour.
What You'll Learn
- Implement a real‑time Fast Fourier Transform on accelerometer data using Arduino DSP libraries
- Calibrate an ADXL345 at 200 Hz sample rate to capture anemometer‑post vibrations with milli‑g resolution
- Log time‑stamped spectral data to a microSD card with an RTC, creating analysis‑ready CSV files
- Design a battery‑powered, handheld instrument with an OLED interface for outdoor deployment

Who This Kit Is For
This kit aligns perfectly with B.Tech ECE/EEE final‑year projects that demand genuine signal‑processing depth, as well as Smart India Hackathon teams building weather or wind‑energy prototypes. ATL Tinkering Lab mentors will find it an ideal bridge to advanced data acquisition, while research groups at IITs, NITs, VIT, and BITS Pilani can use it as a low‑cost platform to study wind‑induced structural vibrations. If you can follow a schematic and have basic Arduino experience, you are ready to build a lab‑grade instrument.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to launch the AI companion trained specifically for this turbulence analyser; if you prefer a human touch, drop a WhatsApp message and our support team will guide you within hours.
Can this analyser be adapted for other vibration monitoring applications like machine condition monitoring?
Yes, the FFT‑based framework is fully adaptable. The AI companion includes notes on adjusting sampling rate, FFT bin resolution, and sensor coupling so you can repurpose the kit for motor diagnostics or structural health monitoring.
Is this kit suitable for a Smart India Hackathon project on wind energy?
Absolutely. The ability to log time‑stamped turbulence spectra and display them live makes it a compelling demo. You will have an MVP in a single build session, leaving ample time to refine your pitch.
Do I need prior FFT or DSP knowledge to complete this build?
The AI companion walks you through the FFT theory at a practical level, and the Arduino library handles the math. You will gain hands‑on DSP intuition without needing a separate signals course first.
ADXL345 at 200Hz measures anemometer post vibration. FFT quantifies turbulence intensity spectrum.
