Office CO2 Tracker Pro Kit with Arduino Uno + LED
Office CO2 Tracker Pro Kit: Model Ocean Acidification with Arduino Uno & CO2 Sensors
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 your workplace into a climate science lab. This kit combines real-time CO2 monitoring with a water acidification model, letting you watch pH drop as you inject CO2 — just like rising atmospheric CO2 acidifies oceans. A perfect cross-disciplinary project for electronics and environmental science.
What You'll Build
You'll assemble a self-contained system that reads ambient CO2, logs data to an SD card, and displays trends on an OLED screen. Then, using the included pH and TDS/EC sensors, you'll bubble controlled CO2 into a water sample, recording the resulting pH decline and conductivity shift. The result is a functional air quality monitor and a tangible model of ocean chemistry.
What You'll Learn
- Calibrating and reading an MH-Z19B NDIR CO2 sensor
- Interfacing analog pH and TDS/EC modules with Arduino Uno R3
- Logging time-stamped environmental data using DS3231 RTC and MicroSD
- Understanding carbonic acid equilibrium and its impact on pH and conductivity

Who This Kit Is For
This kit is built for B.Tech electronics, environmental engineering, and MSc students tackling air quality and climate science projects. It aligns with Smart India Hackathon themes on pollution monitoring, and serves as a ready-made experiment for CBSE Class 12 chemistry demonstrations or ATL Tinkering Labs exploring biochemistry.
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?
Our AI assistant, accessible via QR code, provides real-time debugging. You can also reach our team on WhatsApp for guidance.
Can I use this kit to monitor office CO2 long-term?
Yes. The MicroSD logging allows weeks of continuous data collection, and the OLED displays live readings. Simply connect a USB power supply.
Does this kit measure ocean acidification directly?
It models the process: injecting CO2 into fresh water shows the fundamental chemistry. For seawater experiments, you can substitute your own sample; the sensors calibrate to the relevant range.
Are the chemical sensors pre-calibrated?
The pH and TDS modules come with calibration buffers. You'll perform a quick two-point calibration as part of the learning exercise, ensuring accurate readings.
