## Description

- Indoor carbon dioxide concentration is one of the main indicators of indoor pollution.<br>The gas itself is a colorless, tasteless gas that has little toxicity, but at a high concentration, the amount of oxygen required for human breathing decreases. This situation can cause discomfort to the occupant, and in the case of the elderly and pregnant women, it may threaten their health.<br>- The effects of carbon dioxide concentration on the human body are as follows. (Source: Korea Association of Passive Architecture)<br> ~ 450 ppm Outdoor air in normal daily life<br> 450 to 700 ppm Indoor concentration without health problems even after a long period of time<br> ~ 1,000 ppm no health damage but concentration of people who feel unpleasant<br>~ The concentration that changes your condition, such as feeling sleepy at 2,000 ppm<br>~ 3,000 ppm health damage begins, with people feeling stiff shoulders or headaches<br>3,000 ppm symptoms such as headache, dizziness, etc., and a level that harms one&#39;s health for a long time<br>- In this app, the CO2 concentration is defined as follows.<br>~ 700 ppm sounds good<br>~ 1,000 ppm is normal<br>~ 1500 ppm bad<br>1501 ppm~ Very bad
