Is your bedroom approaching 4 or 5k PPM? The chart screen shotted was at 3300+ and it looks like it kept going up after. Hopefully it's a bad sensor reading, but that is very high. I sleep in a small room with a few people and it's maybe 1500 and noticeable when that happens. Getting to 5k is potentially dangerous for extended periods of time.
replyHi, Co2 levels like that are severely high and will cause you to have a lot of issues. I had some issues with poor ventilation and headaches in my apartment, and my solution was to run the bathroom fan all the time - this gave me enough ventilation to feel much better. You're basically suffocating at 3000 ppm.
replyIt's important to measure this somehow - I do this with a $100 Co2 sensor and display I got off amazon, but you seem to already have these sensors available.
