Test #5 with Sorbent #1

Success?

Notes: My third success! The ppm changed when I lowered it into the water, albeit it took some time. The weird spikes caused earlier on are probably from sensor error. Overall, I would label this a minor success because it did take some time to gain CO2 concentration. I also think my sensor was uncalibrated because the readings were pretty far off from what they should be, seeing as I subjected the chamber with air supplied from indoor air, which has levels of 1000-1500 ppm. This doesn't mean that the sensor can't sense an increase in CO2, though, so I would still label this a success.
