Via GitHub: Too much CO2 in the air affects how well brains function. The Air Quality Object changes color depending on air CO2 content. It’s meant to be a beautiful object which also passively displays information about the surroundings. It makes a normally invisible flow visible, so you can open a window when your air is getting stale.

The SGP30 has two sensors inside, the data sheet shows the sensitivity for hydrogen and ethanol (alcohol) with unstated discrimination between other gases. The CO2 ppm output is a calculated, approximate value based on a model of human respiration. It’s referred to as an equivalent CO2 (eCO2) value in the documentation on https://www.adafruit.com/product/3709.
The term "equivalent carbon dioxide" can be confusing since CO2e is often used as a measure of other gas’s greenhouse effect.
