Arduino Yeast CO2 & Temperature Data Logger Kit
Build a Yeast Fermentation CO2 Data Logger 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.
Monitor CO? production and temperature across three yeast cultures simultaneously to discover the optimal temperature for yeast growth. This kit equips you with the exact sensors and microcontroller to run a rigorous biology experiment, record data to SD card, and display live readings on a 0.96-inch OLED screen. Whether you are preparing a CBSE investigatory project or simply exploring the crossover of biology and electronics, every component works together out of the box.
What You'll Build
You will assemble a portable data logger with three waterproof DS18B20 temperature probes and an MH-Z19B NDIR CO? sensor, all controlled by an Arduino Uno. The device timestamps every reading using a DS3231 real-time clock and saves the data to a microSD card for later graphing. A crisp OLED shows current ppm and temperatures, letting you monitor fermentation in real time without a computer.
What You'll Learn
- Interface multiple 1-Wire temperature sensors and an NDIR CO? sensor with Arduino
- Implement I�C and UART communication protocols for OLED display and RTC module
- Log timestamped sensor data to a microSD card in CSV format for graphing
- Design a controlled biology experiment to test yeast metabolic activity under different thermal conditions

Who This Kit Is For
Ideal for CBSE Class 11-12 biology and computer science students undertaking investigatory projects, B.Tech ECE/EEE students exploring embedded data logging, and participants in Smart India Hackathon designing environmental monitoring solutions. Also perfect for ATL Tinkering Labs introducing sensor integration and data analysis.
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.
Will this kit help me complete my CBSE biology practical?
Yes, the kit is designed for the yeast fermentation experiment in CBSE Class 12 Biology, providing accurate CO? and temperature logging that meets investigatory project requirements, with AI guidance for data analysis and graphing.
How do I set up the three temperature probes for different water baths?
Each DS18B20 probe has a unique 64-bit address, so you can connect all three to a single Arduino pin. The included pre-written code (accessible via the AI companion) handles addressing automatically-just label each probe for its water bath.
Can I use this kit to measure CO? in classroom air instead of yeast?
Absolutely. The MH-Z19B sensor is sensitive enough to detect CO? levels in ambient air (400-2000 ppm), so you can repurpose the kit for classroom ventilation studies after the yeast experiment. The OLED will display real-time ppm.
What if my SD card module doesn't seem to work?
The AI build companion has a dedicated troubleshooting flow-it'll walk you through checking connections, formatting the SD card to FAT32, and verifying the CS pin. If still stuck, WhatsApp support from our team is available.
