The homes are becoming smart & connected in every possible way as the IoT technology grows. So are the cities. Home & office premises usually have sensors to detect air quality. The air quality can have impact on the people using these premises in various ways. As an example, meeting rooms in the offices accumulate more CO2 during long & frequent meetings. But there are no ways to automatically monitor & possible control such events. There are other cases where based on the humidity & temperature of the premises, some people may catch cold, cough & other such diseases.
