Fuel Cell Voltage Logger Kit with Arduino Uno + LED
Fuel Cell Voltage Logger Kit: Monitor Hydrogen Cell Output with Arduino Uno & 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.
Transform a simple Arduino Uno into a professional-grade fuel cell monitoring station. This kit uses the ADS1115 16-bit ADC to capture tiny voltage fluctuations from a hydrogen fuel cell, timestamps every reading with a DS3231 real‑time clock, stores it all on a microSD card, and shows live values on a crisp 0.96‑inch OLED. Whether you’re preparing a CBSE science exhibition, an ATL TinkerFest project, or a renewable energy hackathon prototype, you’ll have a self‑contained logger ready to demonstrate long‑term cell performance with real data.
What You'll Build
You’ll assemble a compact, battery‑operated data logger that connects directly to a hydrogen fuel cell’s output terminals. Once powered on, it measures voltage with millivolt accuracy every second, saves each reading with a date‑time stamp to a CSV file on the SD card, and updates the OLED display instantly. After the experiment, pop out the SD card and open the file on your laptop to plot voltage curves over hours or days — perfect for analysing fuel cell activation, degradation, or load‑response behaviour.
What You'll Learn
- Interfacing a 16‑bit ADS1115 analogue‑to‑digital converter over I2C for noise‑free voltage measurement
- Using a DS3231 RTC to timestamp each logged data point with second‑level accuracy
- Writing structured CSV files to a microSD card via SPI, creating ready‑to‑graph datasets
- Driving an SSD1306 OLED display to show live voltage readings and logger status

Who This Kit Is For
This beginner‑friendly kit fits right into CBSE Class 11–12 physics or chemistry practicals where students analyse electrochemical cells. It’s equally at home in an ATL Tinkering Lab, giving school students a first taste of IoT‑style data collection. B.Tech ECE and EEE freshers use it to understand I2C sensor integration and data logging before tackling larger instrumentation projects. Even Smart India Hackathon teams rely on it to quickly prototype a renewable energy monitoring dashboard.
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 inside your kit. The AI build companion will guide you step by step, and if you still need help, our team is available on WhatsApp within 6 hours.
Can I use this kit to log voltage from a solar panel or a battery?
Yes. The ADS1115 input range (0–5V) works with any low-voltage DC source, so you can measure solar mini‑panels, AA/AAA cells, or even a lemon battery. Just connect the source to the same screw terminals.
How long can it log data?
With a 32 GB SD card (not included, but any standard microSD up to 32 GB works), you can log about 1 reading per second for over a year. The 9V battery powers the logger for roughly 6–8 hours of continuous use; for longer runs, power the Arduino via USB.
Do I need a separate programmer or any soldering?
No soldering required. All connections happen on the 400‑point breadboard using the included jumper wires. The Arduino Uno connects to your computer via USB to upload the code — the AI companion provides the ready‑to‑upload sketch.
ADS1115 precision ADC measures hydrogen fuel cell output voltage over time. Logs to SD with timestamps.
