CO2 모니터1

- Indoor carbon dioxide concentration is one of the main indicators of indoor pollution.
It is a colorless and tasteless gas and has little toxicity, but when the concentration is high, the amount of oxygen required for human breathing decreases. This situation may cause discomfort to occupants and may threaten the health of the elderly and pregnant women.

- The effects on the human body according to carbon dioxide concentration are as follows. (Source-Korea Passive Architecture Association)

~ 450 ppm typical daily outdoor air
450 ~ 700 ppm Indoor concentration that does not cause health problems even if used for a long time
~ 1,000 ppm Concentration that poses no health risk but may cause discomfort to some people
~ 2,000 ppm Concentration that causes changes in physical condition, such as feeling drowsy
~ 3,000 ppm Health damage begins to occur, with some people experiencing stiff shoulders or headaches
3,000 ~ ppm A level that causes symptoms such as headaches and dizziness and is detrimental to health over a long period of time.

- In this app, carbon dioxide concentration is defined as follows.
~700 ppm is good
~1,000 ppm typical
~1500 ppm bad
1501 ppm ~ very poor
