Yeast Growth Temperature Optimum Kit with Arduino Uno + LED
Yeast Growth Temperature Optimum Kit with Arduino Uno + LED: Data-Logging for Perfect Fermentation
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a scientific data logger using three DS18B20 probes to measure temperature at different zones, an MH-Z19B CO2 sensor to track yeast respiration, and an Arduino Uno to log timestamped data to an SD card. By varying incubation temperatures, you'll identify the precise optimum for Saccharomyces cerevisiae growth — exactly the workflow used in biotech labs to characterise microbial productivity.
What You'll Build
A multi-sensor datalogging station that simultaneously tracks temperature and CO2 levels from three fermenting yeast samples. The 0.96" OLED displays real-time readings while the DS3231 RTC stamps each data point. Data is saved to a microSD card in CSV format, ready for analysis in Excel or Python. You'll determine the temperature that yields the highest respiration rate, generating a classic bell-shaped activity curve.
What You'll Learn
- Interfacing multiple DS18B20 temperature probes on a single Arduino 1-Wire bus
- Reading MH-Z19B CO2 sensor data via UART serial communication
- Logging timestamped CSV data to microSD for biological yield analysis
- Interpreting respiration rate curves to calculate temperature optimum

Who This Kit Is For
Ideal for CBSE Class 11-12 students exploring biology and computer-science integration, B.Tech Biotech or ECE undergraduates needing a ready-to-run fermentation experiment, and ATL Tinkering Lab facilitators running inquiry-based science modules. Also valuable for Smart India Hackathon AgriTech tracks requiring rapid prototyping of environmental monitoring gear and for IIT/NIT/VIT/BITS lab curriculum that demands hands-on biological sensing.
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 on the box to access the AI companion that knows this kit inside out. If you need human help, WhatsApp us directly — we respond fast on Indian mobile networks.
Can I use ordinary baker's yeast for the experiment?
Yes, active dry baker's yeast works perfectly. The respirometry method measures CO2 output regardless of strain, so you can compare different yeasts too.
How do I maintain three different incubation temperatures at once?
Use simple water baths at controlled temperatures (e.g., ice + warm water, room temp, 37°C water). Each DS18B20 probe goes into its own yeast flask; the system logs all three channels simultaneously.
Is the data compatible with Excel or Google Sheets?
Absolutely — the SD card stores a plain CSV file with time-stamped rows. Just insert the card into your laptop and open with Excel, Google Sheets, or any plotting tool directly.
DS18B20 + CO2 sensor track yeast activity at different temperatures to find optimal growth temp.
