DIY CO2 Incubator - Arduino and Circuits

Dec 14, 2014· Luckily an Arduino library was developed for this CO2 sensor so I didn't have to do much work to get it up and running. I recommend reading this forum which has the library and some example code (also maintained on github a big shoutout to DirtGambit and Rob Tillaart for developing this). I am currently using the version of the library on page 1 of the forum with no problems.
