I am using a WYND Halo air quality monitor, which was a Kickstarter. It monitors CO2 and other pollutants like VOC, even shows the particle size. Temperature, humidity and light intensity are also tracked. The app shows charts, but I haven't figured out how to download the data. The Halo can also control an air purifier, which has been really handy. It's pretty cool to see the air quality improve while the purifier does its thing. This was especially important when we had horrible air quality due to forest fires. Edit: The app actually let's me export all data as CSV.
