Is the CJMCU811/CCS811 CO2 Sensor reliable? : arduino

+

The sensor you are referring to is, indeed, quite inexpensive and that is mostly because it is not, in fact, an actual CO2 sensor. It''s a VOC (volatile Organic Chemicals) sensor (thing paint fumes, etc.) which does eCO2, which means Equivalent CO2. It basically infers the CO2 concentration from other factors rather than sensing it directly.

May 06, 2021· A Carbon Dioxide Sensor would make sense in a Greenhouse where a level of 1% or 1000ppm would make sense. Atmospheric CO2 is typically 360 to 385 ppm. (< .04%) It only becomes an issue when it reaches several percent of the local atmosphere. Suggesting that CO2 is an indicator of “air quality” (unless in a sealed space) is a bit of a stretch .
