Predictive Maintenance Vibration Monitor Kit with ESP32 + LED
Prevent Costly Downtime: Build an ESP32 Predictive Maintenance Vibration Monitor with OLED
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn any motor into a connected, self-monitoring asset that warns you the moment its vibration signature deviates from the baseline. This kit equips you to deploy a real-time FFT-based anomaly detection system—no cloud dependencies, no recurring fees—just the core of Industry 4.0 condition monitoring running on an ESP32. Whether you’re prototyping for a Smart India Hackathon, delivering a B.Tech capstone on smart factories, or upskilling into industrial automation, you’ll walk away with a portable, battery‑free monitor that logs trends to SD and fires MQTT alerts straight to your phone.
What You'll Build
A dual‑accelerometer vibration monitor that mounts non‑invasively on motor housings, captures high‑speed FFT fingerprints, stores timestamped data on a microSD card, and pushes real‑time anomaly alerts via MQTT. The system runs entirely on embedded hardware, learns a healthy baseline, and flags imbalances, misalignments, or bearing wear with an on‑board OLED dashboard.
What You'll Learn
- Perform real-time FFT analysis on embedded hardware using the ADXL345’s raw output and the ESP32’s DSP capabilities
- Implement MQTT communication with QoS‑1 for reliable alert delivery to any broker or smartphone client
- Timestamp and store vibration fingerprints on a microSD card using a DS3231 RTC for long‑term trend analysis
- Design a rugged, EMI‑resilient power stage with an LM2596 buck converter that runs cleanly in industrial environments

Who This Kit Is For
B.Tech ECE/EEE students building Industry 4.0 capstone projects, industrial automation engineers prototyping condition‑based maintenance rigs, and Smart India Hackathon hardware‑track participants solving predictive maintenance challenges. It’s also a strong choice for M.Tech researchers at IITs, NITs, or VIT/BITS Pilani who need a reproducible data‑logging platform for vibration‑based machine health studies.
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 to open the AI companion trained on this exact kit; it guides you through wiring, calibration, and code uploads step by step. For persistent issues, drop a WhatsApp message to the Compoden support team included in the box.
Do I need prior experience with FFT or MQTT?
Not at all. The AI companion starts with accelerometer calibration, walks you through FFT library integration, and helps you configure a free MQTT broker—no guesswork required. Some comfort with Arduino IDE and basic soldering will accelerate your build.
Can this kit monitor pumps or CNC spindles, not just motors?
Yes. The dual ADXL345 sensors mount on any rotating machinery housing; the companion covers mounting tape selection and wiring for different vibration planes, so you can apply the same FFT baseline technique to pumps, compressors, or spindle bearings.
Is the kit tied to a specific MQTT broker, or can I use a free one?
The firmware is broker‑agnostic. The companion shows you how to point it at test.mosquitto.org or HiveMQ Cloud’s free tier, and explains QoS settings so you never miss a critical alert.
ADXL345 logs motor vibration FFT fingerprint. ESP32 compares against baseline and alerts on deviation via MQTT.
