Dirt Chamber

I was offered the opportunity to help a faculty member automate a temperature and humidity controlled chamber and I jumped at the chance.

The faculty member a Clay Goodman, gave me the DO of being able to control the temperature and humidity within the chamber, while also measuring the CO2 during set periods of time. This data then needed to be exported into an excel sheet so data processing could occur to see and predict trends.

The point of the study is to see the effect of various dirt cracks on CO2 flux in a controlled environment to better understand the relationship between dirt and CO2 levels in the atmosphere.

I used an Arduino Uno as the primary microprocessor for this project, the project as well as the code is explained in the video below.

I was able to get the code and the chamber in a working state before I had to leave for my summer internship.

However the next goals for the project were to clean up the cable and begin running tests.

Depending on the results of this phase of testing a field ready testing device may be created in the future to test flux levels as they occur.
