AIR QUALITY NDI ECO2

Gulu la Air Quality Sensor limagwiritsa ntchito sensor yokhala ndi gawo la CCS811. Chip chaching'onochi sichimayesa mlingo wa CO2 (carbon dioxide) koma m'malo mwake mlingo wa gulu la mpweya wotchedwa volatile organic compounds (VOCs). Mukakhala m’nyumba, mulingo wa mpweya umenewu umakwera kwambiri mofanana ndi wa CO2, motero ukhoza kugwiritsidwa ntchito poyerekezera mlingo wa CO2 (wotchedwa CO2 wofanana kapena eCO2).
Mulingo wa CO2 mumpweya womwe timapuma umakhudza mwachindunji moyo wathu. Miyezo ya CO2 ndiyofunikira makamaka kuchokera kumalo azaumoyo wa anthu view monga, kunena mwachidule, iwo ali muyeso wa kuchuluka kwa momwe timapuma mpweya wa anthu ena. Anthufe timapuma mpweya wa CO2 kotero, ngati anthu angapo ali m'chipinda chosakhala bwino, mlingo wa CO2 udzawonjezeka pang'onopang'ono. Izi ndizofanana ndi ma aerosols omwe amafalitsa chimfine, chimfine ndi Coronavirus pomwe anthu amapumira limodzi.
Kukhudzika kwina kofunikira kwa milingo ya CO2 ndikugwira ntchito kwachidziwitso - momwe mungaganizire bwino. Kafukufukuyu (mwa ena ambiri) ali ndi zopeza zosangalatsa. Mawu otsatirawa akuchokera ku National Center for Biotechnology Information ku USA: "pa 1,000 ppm CO2, kuchepa kwapang'onopang'ono komanso kuwerengetsa kunachitika mu masikelo asanu ndi limodzi mwa asanu ndi anayi opangira zisankho. Pa 2,500 ppm, kuchepetsedwa kwakukulu komanso kofunikira kunachitika pamiyeso isanu ndi iwiri yakuchita zisankho” Source: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3548274/
