Can the Air app detect specific gases like CO2?

The VOC sensor in the S61 can only measure the concentration of VOCs. The sensor cannot distinguish between different VOC sources, but rather alerts you to the presence of a VOC.

Air cannot detect other pollutants such as dust or smoke, outdoor air pollutants, carbon dioxide and gases such as carbon monoxide or methane.
