Sensa ya gasi ndi imodzi mwa mitundu yofunikira kwambiri yowonera gasi

Chidziwitso chatsopano chokhudza thanzi la zowononga mpweya kapena zosasunthika chikupitilira kutsindika kufunika kowunika momwe mpweya ulili mkati ndi kunja.Zowonongeka zambiri, ngakhale pazigawo zotsatizana, zitha kukhala zovulaza thanzi la munthu pakangopita nthawi yochepa.Kuchulukirachulukira kwazinthu zogulitsa ndi mafakitale zimatha kutulutsa zinthu zowopsa zomwe zimadziwika, kuphatikiza mipando, magalimoto onyamula anthu ndi magalimoto akumafakitale.Anthu akuyang'anitsitsa kwambiri kuti azindikire zowonongeka kwa mpweya, kuyembekezera kuchepetsa kapena kuthetsa chiopsezo chathanzichi pokhazikitsa njira zoyenera komanso zothandiza poyankha.
Mabungwe ambiri a mayiko ndi apadziko lonse akhala akugwira ntchito kuti apange malangizo, malamulo ndi miyezo yowunikira mpweya wabwino m'mafakitale, zamankhwala, kunja, maofesi amkati ndi malo okhalamo.Malangizowa amalola opanga kutsimikizira zomwe akugulitsa ndikudziwitsanso ogwiritsa ntchito za milingo yovomerezeka pang'ono yazinthu zowononga mpweya.

Mwachitsanzo, bungwe la US Environmental Protection Agency (EPA) limagwiritsa ntchito sayansi yamakono kupanga malamulo omwe amachepetsa komanso kuchepetsa kuwonongeka kwa mpweya.Pazowononga zofala kwambiri, EPA imasonkhanitsa deta zaka zisanu zilizonse kuti iwunikenso kukwanira kwa malamulo a mpweya.Bungweli lidazindikiranso mankhwala enaake omwe angakhudze mpweya wabwino komanso magwero ake, monga magalimoto, magalimoto ndi malo opangira magetsi.Chimodzi mwa zolinga zazikulu za EPA ndikugwirizanitsa zonyansa kuzinthu zazikulu zomwe zingayambitse thanzi.
Zida zinayi zazikulu zowononga mpweya wakunja ndi 03, NO2, SO2, ndi CO. Mipweyayi imatha kuyang'aniridwa pogwiritsa ntchito zida zovomerezeka za EPA.Kuphatikizidwa ndi deta yochokera ku particle detectors, miyeso imagwiritsidwanso ntchito kuwerengera Air Quality Index (AQ).Zowonongeka mumlengalenga wamkati zimakhala zenizeni ndipo zimadalira ngati ndi nyumba yogona kapena ofesi, chiwerengero cha anthu, mtundu wa mipando, mpweya wabwino ndi zina.Zowonongeka zazikulu ndi CO2, formaldehyde ndi benzene.Kuyang'anira zowonongeka kwa mpweya ndikofunika kwambiri, koma njira zamakono zomwe zilipo panopa sizikukwaniritsa zomwe anthu akuyembekezera masiku ano pokhudzana ndi khalidwe la deta komanso mtengo wake.
M'zaka zaposachedwa, opanga ma sensor a gasi atengera umisiri watsopano komanso mawonekedwe opangira, kuphatikiza ma electrolyte osagwiritsa ntchito madzi m'masensa a electrochemical.Kupita patsogolo kwaukadaulo uku kwayendetsa kukhathamiritsa kwa mphamvu, mtengo ndi kukula.
Kusintha ndi kuchotsedwa kwa masensa a gasi kumafunanso kulondola bwino.Njira zamakono zamitundu yosiyanasiyana zikuyendetsanso chitukuko cha mphamvu zatsopano zama sensor a gasi komanso kukula kwa msika.Kutsogola pazamagetsi, zosefera gasi, kulongedza, ndi kusanthula kwa data pa board kungapangitse kukhazikika kwa sensor komanso kulondola.Mitundu yolosera ndi ma aligorivimu omwe amagwiritsa ntchito ukadaulo wanzeru zopanga komanso kusanthula kwa data paboard alinso amphamvu kwambiri, zomwe ndizofunikira kwambiri pakuwongolera magwiridwe antchito a sensa.
