Short summary
This study presents a new, low-cost sensor system for measuring soil CO2 gas continuously over long periods. Built using easy-to-get hardware components, the system costs USD 700. It was tested for six months in desert soil, proving to be reliable, easy to maintain, and capable of capturing important changes in soil CO2. The CO2 flux calculations from this system closely matched those from a standard measurement device, making it a practical tool for research requiring multiple sensor systems.
