I am part of a team of Student Engineers from Minnesota State University creating a Sensor to measure CO2 concentrations in sub-surface soils. Check out the GitHub – https://github.com/bellahenkel/Soil-Sensing-Device this was created by Last semesters wonderful team.

We are using the Alphasense IRC-a1 CO2 sensor with NDIR CO2 transmitter…[Read more]
