Soil Carbon Sequestration Monitor Kit with Arduino Uno & CO₂ Sensor

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

Soil isn’t just dirt — it’s one of Earth’s largest carbon sinks, and you can measure its storage potential with real sensors. This kit lets you build a portable monitor that reads soil electrical conductivity (TDS) and atmospheric CO₂ concentration simultaneously, then logs the data with timestamps. Compare garden soil, agricultural field soil, and forest floor samples to see which holds more carbon, a perfect integration of biology and electronics for CBSE Class 11–12, ATL tinkering labs, or a Smart India Hackathon climate prototype.

What You'll Build

You'll assemble an Arduino Uno-based handheld data logger. The TDS EC meter probe reads water-extractable ion levels — strongly tied to soil organic carbon — while the MH-Z19B NDIR sensor tracks CO₂ in the air pocket above the soil. Timestamped readings are saved to a microSD card and displayed live on a 0.96-inch OLED screen. Head out to a school garden, a nearby farm, or a campus plot and capture side‑by‑side data from different soil types in a single afternoon.

What You'll Learn

• How electrical conductivity correlates with soil organic carbon content
• Interfacing and calibrating the MH-Z19B CO₂ sensor with Arduino Uno
• Real‑time data logging using a DS3231 RTC and microSD module
• Interpreting time‑series readings to compare carbon storage across soil types
