References to Soil CO2 respiration methods

Also found this recent article:

And we had many discussions on this on the Hackteria forum:


another recent and “more open” paper
A low-cost versatile system for continuous real-time respiratory activity measurement as a tool in environmental research - ScienceDirect!

And look i found the paper for download here!


They use the Sen 0220 NDIR CO2 sensor. :wink:
I also came across this one from 2014, concentrated on indoor CO2, which has a nice description of how two of the diferent types of sensors measure CO2 (chemical, ndir).
