Yes the ABC is often an issue and can lead to an underestimation of the CO2 values.
This often happens in non ventilated and relatively air tight rooms.
We collect air quality data from many schools and see this happening in some classrooms that even over the unoccupied time during the night the CO2 will not reach ambient levels the next morning.
- p1esk 4y agoWhat do you think about Air Quality Egg product [1]? How does it compare to Aranet4? How do these two compare to AirGradient ONE product? Which chemicals are most important to monitor in a typical 40yo house in Florida: CO2, CO, NO2, SO2, O3? [1] https://airqualityegg.com/shop https://airqualityegg.com/shop
- ahaucnx 4y agoI do not own an Air Quality Egg or an Aranet so I cannot really comment on both. In general most of the low cost monitors use similar sensor modules, e.g. Plantower for PM, Sensirion for TVOCs etc. What is important to ensure that the CO2 sensor is an NDIR or photo accoustic and not using estimated CO2 via a TVOC sensor that is very inaccurate. I would start measuring PM, CO2 and TVOCs in the house to first understand more about how well the HVAC system works. Then optimize it for low CO2 and PM. This should then flush out most of the internal pollution sources as well.
