Yeast CO2 and Temperature Monitor Kit with Arduino Uno + OLED Logger

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

See yeast metabolism in real time by measuring CO2 production at three different temperatures simultaneously. This kit turns a standard biology experiment into a precision data-collection project - you'll capture CO2, temperature, and timestamps, store results on a MicroSD card, and display live values on an OLED screen, all without a single line of code-writing guesswork.

What You'll Build

You'll construct a multi-channel environmental monitor that tracks yeast activity across three culture vessels. One DS18B20 probe sits in each vessel alongside the shared MH-Z19B CO2 sensor chamber, while the DS3231 RTC timestamps every reading. The OLED screen shows live CO2 (ppm), temperature for each probe, and elapsed time, while the MicroSD module logs the full dataset for later graphing - exactly what you need to determine the optimum fermentation temperature.

What You'll Learn

• Calibrate and read a non-dispersive infrared CO2 sensor (MH-Z19B) over UART
• Interface three DS18B20 OneWire temperature probes on a single Arduino pin
• Log timestamped sensor data to a MicroSD card using an RTC module for precise timekeeping
• Visualize real-time multi-variable data on a 0.96-inch I2C OLED display

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for CBSE Class 11-12 biology investigations, B.Sc. biotechnology lab work, and ATL Tinkering Lab projects that require quantitative microbial growth analysis. It fits neatly into Smart India Hackathon challenges around smart farming or fermentation monitoring, and is robust enough for IIT/NIT/VIT bioengineering mini-projects where accurate multi-sensor logging matters.

Built and Backed by Compoden
