Indoor Air Quality Detection During Covid19 Pandemic (IAQD ...

The main way indoor carbon dioxide affects our health is through our brains. As carbon dioxide levels in a room increase, the gas starts crowding out the oxygen. Carbon dioxide is considered a simple asphyxiant because it reduces the amount of oxygen we absorb from each breath. If indoor carbon dioxide levels get too high (around 40, 000 ppm), your life may be in danger. At levels we are more ...
