Short summary
Low-cost air enquirer kits, including CO2 and environmental parameter sensors, have been designed, built, and tested in a new steady-state through-flow chamber for simultaneous measurements of CO2 fluxes in soil and CO2 concentrations in air. A CO2 calibration and multiparametric fitting reduced the total uncertainty of CO2 concentration by 90 %. This system allows continuous measurement of CO2 fluxes and CO2 ambient air, with low cost (EUR 1200), low energy demand (<5 W), and low maintenance.
