Office CO2 Tracker Kit with Arduino Mega
Office CO2 Tracker Kit with Arduino Mega + OLED - Advanced Soil CO2 Flux Monitoring for Environmental STEM 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.
This advanced kit empowers you to build a dual-purpose CO2 tracker that captures carbon dioxide levels in both workplace air and soil core samples, logging granular data to a microSD card for decomposition analysis. Whether you're quantifying indoor air quality in an office or measuring CO2 flux from organic matter in soil, the system delivers timestamped, multi-sensor readings to your OLED display and stored logs. It's a ready-to-deploy environmental monitoring station built around the robust Arduino Mega 2560, specifically tailored for research-grade soil respiration and air quality experiments.
What You'll Build
You'll assemble a waterproof, field-ready unit that uses two MH-Z19B NDIR CO2 sensors and four DS18B20 temperature probes to monitor CO2 concentration and temperature at multiple points. Real-time values are displayed on the 0.96-inch OLED, while the DS3231 RTC ensures every data point is accurately timestamped and saved to a microSD card via the dedicated module. The final device can be partially buried to track soil CO2 flux from decomposition or placed on a desk for continuous office air quality monitoring.
What You'll Learn
- Interfacing multiple I2C and serial sensors on the Arduino Mega 2560 without bus conflicts or timing issues
- Calibrating MH-Z19B NDIR CO2 sensors for precise soil gas sampling, including warm-up and zero-point routines
- Implementing RTC-based data logging with microSD storage for long-term environmental studies
- Correlating CO2 flux patterns with vertical temperature profiles to model decomposition rates

Who This Kit Is For
Designed for B.Tech ECE/EEE students tackling environmental monitoring capstone projects, CBSE Class 12 innovators at ATL Tinkering Labs, and research interns at IIT, NIT, VIT, or BITS labs studying soil respiration. It also serves Smart India Hackathon teams needing a rugged, deployable CO2 flux data logger for agricultural or workplace air quality challenges.
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?
The AI companion offers real-time, step-by-step assistance for wiring, coding, and calibration. For anything beyond its scope, our team responds via WhatsApp to get you unstuck quickly.
Can I use this kit to measure CO2 levels in a conference room?
Yes, the dual-sensor setup monitors ambient air quality with high accuracy. Simply place the unit in the room and it will log CO2 concentration and temperature, helping you assess ventilation effectiveness.
How long can it log data in the field for soil flux experiments?
With a fresh 9V battery, the system can log for approximately 8-10 hours continuously. For extended field deployments, you can easily swap in a larger power pack using the battery snap connector.
Do I need prior soldering experience?
Basic soldering is required for the PCB prototype board and sensor connections. The kit includes a soldering iron and wire, and the AI guide walks you through each solder joint with clear visuals, making it achievable even if you're building your first soldered project.
Workplace Air - CO2 and temperature sensors in soil core measure carbon dioxide flux from decomposition activity.
