# Test #5 with Sorbent #1 ![](/files/Ot2ynF6u4WLfcLb5cRye) 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. Time water added: 8:30 Time water taken away: 8:32 Start ppm: 417 End ppm: 540 Rise ppm: 123 Total time frame: 4 hr 29 min (holy cow!) Experiment time frame: 4 hr 26 min (I started it a little too early) Test chamber: MK3 --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
