Fermentation CO2 Production Logger Kit with Arduino Uno + Sensor
Fermentation CO2 Production Logger Kit: Arduino Uno + MH-Z19B Sensor for Quantified Biology Projects
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 traditional biology experiment into a precise, data-driven investigation. With this kit, students and hobbyists can track real-time CO₂ production from yeast fermentation inside a sealed vessel, capturing every rise in concentration over 48 hours. No more guesswork—just a clear ppm graph and timestamped SD card logs ready for analysis.
What You'll Build
You’ll assemble a self-contained CO₂ monitoring station that logs readings continuously. The MH-Z19B sensor measures CO₂ in parts per million, the DS3231 real-time clock stamps every data point, and the microSD module saves everything to a file. The 0.96‑inch OLED displays live ppm, runtime, and logging status so you can monitor progress at a glance—perfect for tracking how different sugar concentrations, yeast strains, or temperatures affect fermentation rate.
What You'll Learn
- Interface a non-dispersive infrared (NDIR) CO₂ sensor with Arduino and interpret raw ppm data
- Configure an I²C real‑time clock to timestamp sensor readings for long‑term experiments
- Write structured data to a microSD card and process CSV files for graphing fermentation curves
- Debug sensor calibration, power management, and serial communication in a multi‑module system

Who This Kit Is For
Students tackling CBSE Class 11-12 biology or chemistry investigations who need quantitative CO₂ data, B.Tech first‑year sensor lab projects, and ATL Tinkering Lab innovators prototyping environmental monitors. Also ideal for Smart India Hackathon teams building smart agriculture or bio‑reactor demos, and for anyone at IIT/NIT/VIT/BITS exploring fermentation kinetics with real hardware.
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 kit for the AI companion that walks you through every connection and line of code, or reach us on WhatsApp for a human backup.
Can I use fresh yeast and table sugar, or do I need lab-grade materials?
Ordinary baker’s yeast and common sugar work perfectly. The kit is designed to detect typical fermentation CO₂ levels—you’ll see clear concentration rises within the first hour.
How do I seal the fermentation vessel without affecting the sensor?
Use a container with a tight lid and drill a small hole for the sensor’s cable. The MH-Z19B’s measurement chamber is sealed internally, so a well‑sealed vessel won’t harm readings. We include detailed guidance in the build companion.
Does this kit need a computer while running, or can it log standalone?
Once the Arduino is programmed, the kit logs entirely standalone to the microSD card. The 9V battery snap powers it for multi‑hour runs, so you can place the whole setup in an incubator or controlled environment without a PC.
MH-Z19B in sealed vessel tracks CO2 from yeast fermentation over 48 hours.
