Office CO2 Tracker Kit with Arduino Uno + LED
Office CO2 Tracker Kit – Measure Soil Carbon Storage & Indoor Air Quality with Arduino
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
With this kit, you’ll build a portable data logger that measures both CO2 concentration and soil electrical conductivity, enabling a hands-on comparison of carbon storage across different soil types. Whether you’re investigating climate science, participating in a Smart India Hackathon, or preparing a CBSE Class 12 investigatory project, this Arduino-powered system turns abstract carbon cycle concepts into tangible, logged data.
What You'll Build
A dual-parameter environmental monitor that simultaneously records soil conductivity and CO2 levels over time. The 0.96-inch OLED displays real-time readings while the DS3231 real-time clock stamps every measurement onto a microSD card, creating a permanent record for analysis. Deploy the kit to compare carbon storage capacity in loam, clay, and sandy soils by observing how different soil types affect CO2 release and electrical conductivity, mimicking real-world soil carbon sequestration studies.
What You'll Learn
- Calibrate and interface a non-dispersive infrared (NDIR) CO2 sensor (MH-Z19B) with Arduino Uno to measure atmospheric and soil-emitted CO2.
- Measure soil electrical conductivity using a TDS EC meter and relate it to ion availability and carbon mineralization activity.
- Log time-stamped sensor data to a microSD card using the DS3231 RTC and interpret trends across different soil samples.
- Assemble a breadboard circuit with pull-down resistors, decoupling capacitors, and I2C OLED display for robust field-ready logging.

Can this kit measure CO2 in an office or classroom for air quality monitoring?
Absolutely. The MH-Z19B sensor is ideal for indoor CO2 tracking, and the same circuit can be switched to monitor workplace air quality. The provided code includes modes for both soil gas sampling and ambient indoor measurement.
How do I compare carbon storage capacity between different soil types?
Measure baseline CO2, then seal a soil sample in a container with the sensor. As microbes respire, the CO2 rise rate correlates with organic carbon mineralization. Higher conductivity often indicates greater ionic activity from decomposition, allowing you to rank soil types by carbon storage potential.
Is this kit suitable for school competitions like CBSE National Science Exhibition or IRIS?
Yes. The kit covers core concepts in climate change, sensor technology, and data logging — all highly relevant for competitive science fair projects. The microSD data export makes analysis and presentation easy.
Workplace Air — Soil conductivity + CO2 in different soil types compare carbon storage capacity.
