Fuel Cell Hydrogen Generator Monitor Kit with Arduino Uno + Sensor
Track Electrolysis Hydrogen Output in Real-Time with Arduino Uno – Fuel Cell Monitor Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit transforms a standard Arduino Uno into a precision monitor for your water electrolysis setup. By tracking the current flowing through the cell and the volume of hydrogen gas produced, it calculates and displays mmol of H₂ per minute on a bright OLED screen. It’s a hands-on tool for exploring clean energy concepts, Faraday’s laws, and sensor integration — exactly the kind of project that stands out in science fairs, CBSE physics practicals, or B.Tech mini-projects.
What You'll Build
You’ll assemble a self-contained instrument that reads the ACS712 current sensor to monitor electrolysis efficiency, counts pulses from a YF-S201 flow sensor to estimate hydrogen output, and timestamps every reading via the DS3231 real-time clock. The final system shows live mmol/min values and can serve as the dashboard for a tabletop hydrogen generator, a classroom demonstration model, or a proof-of-concept for green fuel cells.
What You'll Learn
- Interface analog current sensors and pulse-based flow sensors with Arduino
- Compute hydrogen production rate using electrolysis current and Faraday’s law
- Display dynamic numerical data on an I2C OLED screen with clear formatting
- Incorporate a real-time clock to log measurements and create timestamped records

Who This Kit Is For
CBSE Class 11–12 students turning a chemistry concept into a working instrument, B.Tech ECE/EEE undergraduates exploring sensor integration for green energy, Smart India Hackathon teams prototyping hydrogen monitoring, and ATL tinkering lab facilitators who need a complete, ready-to-assemble fuel cell demo. If you’ve ever wanted to see real-time mmol/min from your own electrolyzer, this kit gets you there without hunting for compatible parts.
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?
The AI companion (scanned from the box) gives exact wiring diagrams, code explanations, and troubleshooting tips. If a hardware issue arises, our WhatsApp support typically responds within a few hours, and we can share replacement photos or setup videos instantly.
Can I modify this kit to measure higher currents for a larger electrolyzer?
Yes. The ACS712 5A handles currents up to 5A, but the same circuit and code structure works with the ACS712 20A or 30A modules. Our AI companion can guide that pin-compatible swap, so you can scale up safely.
Does the kit include the electrolyzer and hydrogen storage?
No. This kit focuses on the monitoring electronics. You supply your own electrolysis cell, tubing, and enclosure. That keeps the project flexible—use a small glass cell or a larger membrane setup, and our sensors will measure the output.
What units appear on the OLED, and can I change them?
The pre-loaded sketch displays mmol of H₂ per minute, computed from the flow sensor’s pulse rate and the current-based Faraday calculation. You can easily modify the Arduino code to show mL/min or L/hour—the companion includes commented code sections to make that switch in seconds.
ACS712 monitors electrolysis current. Flow sensor estimates hydrogen production rate. OLED shows mmol per minute.
