- asdff 5y agoNot exactly inexpensive. These are "low cost" in that they don't cost $20,000 like the sensors used by government agencies, but they aren't what I as a consumer think low cost means.
- numpad0 5y agoI can recommend against one type of bad sensors. VOC sensors paired with a temperature sensor that can generate “eCO2” value is known bad, such as CCS811/BME280 combo board. Those sensors guesstimate CO2 concentration from air temperature and changes in ambient alcohol/acetone/hydrocarbon levels, which drifts into positive infinity and is simply do not correlate well with actual CO2 level. Those sensors are dirt cheap, and can still be used as a rule of thumb to encourage regular ventilation, but are nothing more than that. If you want to actually see CO2 levels, avoid those.
