yea I recently started monitoring my homes CO2 levels with some DIY sensors. You need to enter your elevation above sea level or have a pressure sensor hooked up.
So if the op set a static pressure I assume that would affect the readings a lot.
Calibration is also just the sensor looking for the co2 floor (ie the lowest level possible). You need to do this weekly or monthly maybe..?
Auto calibration just sets the lowest level it has recently seen as the floor.
- ahaucnx 4y agoWhat was your experience with the DIY monitor that you build? I am asking because we maintain an open source / open hardware indoor air quality project [1] that we continuously update and I am interested to learn about missing features we might have. Did your build have a dedicated pressure sensor? [1] https://www.airgradient.com/open-airgradient/kits/ https://www.airgradient.com/open-airgradient/kits/
