Mpweya wa carbon dioxide ndi mpweya wopanda mtundu komanso wopanda fungo.Ndi chimodzi mwa zigawo zofunika kwambiri za mlengalenga.Monga chogwirizira chachikulu cha photosynthesis, kuchuluka kwa CARBON dioxide kumakhudzana mwachindunji ndi momwe mbewu zimagwirira ntchito, ndipo zimatsimikizira kukula ndi chitukuko, siteji ya kukhwima, kukana kupsinjika, mtundu ndi zokolola za mbewu.Koma zambiri za izo sizidzangotulutsa wowonjezera kutentha ndi zotsatira zina, komanso kuvulaza thanzi laumunthu.Pa 0.3 peresenti, anthu amamva kupweteka mutu, ndipo pa 4-5 peresenti amamva chizungulire.Malo amkati, makamaka m'zipinda zoziziritsa mpweya, amakhala otsekedwa.Ngati palibe mpweya wabwino kwa nthawi yayitali, kuchuluka kwa mpweya woipa kumawonjezeka pang'onopang'ono, zomwe zimawononga thanzi la munthu.Malinga ndi mulingo wa mpweya wamkati womwe unakhazikitsidwa mu 2003, kuchuluka kwa gawo la mpweya woipa wa tsiku ndi tsiku sayenera kupitirira 0.1%.
Ndi kukula kosalekeza kwa sayansi ndi ukadaulo, kuwonjezereka kwa moyo wa anthu komanso chidwi chowonjezeka cha anthu pachitetezo cha chilengedwe, kuyang'anira kachulukidwe ndi kuwongolera mpweya wa carbon dioxide kwakhala kufunikira kowonjezereka kwa mpweya, ulimi, chithandizo chamankhwala, magalimoto ndi chitetezo cha chilengedwe. .Mpweya woipa masensa chimagwiritsidwa ntchito makampani, ulimi, chitetezo dziko, mankhwala ndi thanzi, kuteteza chilengedwe, zakuthambo ndi zina.
Mfundo yogwira ntchito ya carbon dioxide sensor ikufotokozedwa pansipa.
Chinthu chilichonse chimakhala ndi mawonekedwe akeake a mizere yowala, komanso mawonekedwe ake amayamwa, monganso ma molekyulu a mpweya woipa wa carbon dioxide.Kugwedezeka kwa lattice kwa zida za ceramic ndi kusuntha kwa ma elekitironi kumakhala ndi chopinga, kutentha kumakwera, kugwedezeka kwa lattice kumalimbikitsidwa, matalikidwe amachulukira, cholepheretsa cha elekitironi chimalimbikitsidwa.Malingana ndi chiphunzitso cha mayamwidwe a gasi, pamene kutalika kwa mawonekedwe a kuwala kwa gwero kumagwirizana ndi kuyamwa kwa gasi, kuyamwa kwa resonance kudzachitika, ndipo kuyamwa kwake kumagwirizana ndi kuchuluka kwa mpweya.Kuchuluka kwa gasi kungayesedwe poyeza mphamvu ya kuyamwa kwa kuwala.
Pakali pano, pali mitundu yambiri ya carbon dioxide masensa, kuphatikizapo matenthedwe madutsidwe mtundu, densitometer mtundu, cheza mayamwidwe mtundu, magetsi madutsidwe mtundu, mtundu mayamwidwe mankhwala, mtundu electrochemical, chromatography mtundu, misa sipekitiramu mtundu, infuraredi kuwala mtundu ndi zina zotero.
Infuraredi mayamwidwe carbon dioxide mpweya kachipangizo zachokera mfundo kuti mayamwidwe sipekitiramu mpweya amasiyana ndi zinthu zosiyanasiyana.Carbon dioxide sensor ndi infrared nyali dalaivala woyendetsa dera mkati mwa gulu lokhazikika la infrared, kuyamwa kwa gasi poyesedwa, kusintha kwa matalikidwe a kuwala kwa infrared, kachiwiri kudzera mu mawerengedwe a cheke kusintha kwa ndende ya gasi, chizindikiro chotulutsa sensa pambuyo kusefa, kukonza bwino ndi Kutolere ADC ndi kutembenuka, athandizira kwa microprocessor, dongosolo microprocessor malinga ndi anasonkhanitsa alipirire lolingana kutentha, kuthamanga, kutentha, kuthamanga, potsiriza anawerengetsera mpweya woipa kachulukidwe linanena bungwe kwa chipangizo anasonyeza poyesedwa.Imaphatikizanso zowonera za mayamwidwe a laser diode, ma photoacoustic spectroscopy, mawonekedwe owonjezera pamitsempha ndi mawonekedwe osawoneka bwino a infrared.Mayamwidwe a infrared sensor ali ndi zabwino zambiri, kukhudzika kwakukulu, kuthamanga kusanthula mwachangu, kukhazikika bwino, ndi zina zambiri.
Katswiri wamagetsi a CARBON dioxide gas sensor ndi sensa yamagetsi yomwe imasintha ndende (kapena kupanikizika pang'ono) kwa mpweya woipa kukhala chizindikiro chamagetsi kudzera mu electrochemical reaction.Malinga ndi kuzindikira kwa zizindikiro zamagetsi, mtundu wa electrochemical umagawidwa kukhala mtundu womwe ungatheke, mtundu wamakono ndi mtundu wa capacitance.Malinga ndi mawonekedwe a electrolyte, pali ma electrolyte amadzimadzi ndi ma electrolyte olimba.Kuyambira zaka za m'ma 1970, ofufuza ofufuza akhudzidwa kwambiri ndi ma electrolyte CARBON dioxide sensors.Mfundo ya mphamvu yolimba ya electrolyte CARBON dioxide sensor ndi yakuti zinthu zomwe zimakhudzidwa ndi mpweya zimapanga ma ions pamene zikudutsa mu mpweya, motero kupanga mphamvu ya electromotive ndikuyesa mphamvu ya electromotive kuti ayese gawo la voliyumu ya mpweya.
Kugwiritsa ntchito matenthedwe osiyanasiyana a CARBON dioxide ndi mpweya wina wa carbon dioxide gas sensa ndiyonso yoyamba yomwe imagwiritsidwa ntchito pozindikira sensa ya carbon dioxide.Koma chidwi chake ndi chochepa.
Pamwamba pamayimbidwe amafunde (mawona) mpweya sensa mu piezoelectric kristalo ❖ kuyanika wosanjikiza kusankha adsorption wa mpweya tcheru filimu mpweya, pamene mpweya tcheru mafilimu kucheza ndi mpweya poyesedwa, kupanga mpweya tcheru filimu ❖ kuyanika khalidwe, khalidwe monga viscoelasticity ndi kusintha kwa ma conductivity, kumapangitsa kuti ma frequency acoustic wave a piezoelectric crystal agwedezeke, kuti azindikire kuchuluka kwa mpweya.The surface acoustic wave (SAW) gas sensor ndi mtundu wa sensa ya misa.Kuphatikiza apo, sensa ya quartz crystal microbalance gas imagwiranso ntchito mofananamo ndi sensa ya SAW, kotero imakhalanso ya sensa yovuta kwambiri.The misa tcheru kachipangizo palokha alibe selectivity kwa mpweya kapena nthunzi, ndi selectivity ake monga kachipangizo kachipangizo kokha zimadalira katundu wa pamwamba ❖ kuyanika zinthu.
The semiconductor carbon dioxide mpweya kachipangizo AMAGWIRITSA NTCHITO semiconductor mpweya sensa monga mpweya sensa, ndi zitsulo okusayidi semiconductor mpweya woipa mpweya sensa ali ndi makhalidwe a kuyankha mofulumira, amphamvu kukana chilengedwe ndi dongosolo khola.
