Mhedzisiro yebasa racho rutsigirwa neyekupihwa kweRussian Science Nheyo dzakabudiswa mumagazini yeSensors. Iko kusungwa kweCarbon dioxide mumhepo ndeye 400 PPM (zvikamu pamamiriyoni), iyi ndeye 0.04 muzana yehuwandu hwekusunganidzwa. Munzvimbo dziri padyo nemabhizimusi emumaindasitiri, iyo co2 zvemukati chiyero yakakwira kupfuura inenge 1.5 times - 600 ppm. Kusimbisa kanopfuura 800 ppm kunoonekwa sekukuvadza hutano hwevanhu.
Kuwedzera kweCarbon dioxide mumhepo kunokanganisa chete kugara zvakanaka, asiwo kunotungamira kudziya kwepasirese. Naizvozvo, nyika ine kudiwa kuri kukura kwevanonzwedza chaiko kunogona kudzora kusungwa kwemagirazi greenhouse magasi. Nhasi, izvi zvinoshandisa zvisiri kuparadzira infrared spectroscopy. Iyo sensor ine infrarared Source, mukamuri yekuyera, chimbo chimbambaira uye infrared detector.
Iyo yefaira yakaiswa pamberi peilsatictor, inobata mwenje yese, kunze kwekunge imwe wavelength, iyo inogona kutorwa nemamorekuru egasi rakatsemurwa. Kana gasi rinopinda mukamuri, rayo rekusangana rinoyerwa nekuda kwekunyudzwa kweimwe wavelength mune infrared spectrum.
Iyo sensor inokurudzirwa nemasayendisiti akasiyana neayo analogues neyakaenzana. Zvikamu zvechromium, goridhe uye silicon zvinoiswa kune iyo chaiyo substrate. Silicon akagadzira maNanoscale Cylinders, anonzi methaatoms. Inowanikwa mune imwe kurongeka, vanoumba pamusoro pemitauro ine huwandu hwakasiyana husiri mune zvakasikwa. Kumusoro, iyo Inoshanda Deyer yeSensor ine polymer Polymethylene yeiyo Bluuanidine, iyo inoshandiswa, semuenzaniso, seanosvina.
Mashandiro ebasa ane kuyera iyo wavelength yemwenje yakaratidzwa, iyo inobatwa uchishandisa PhotoDetector, uye inoshandiswa kushandura mafoto muzvazvino. Kana co2 gasi inopinda mukamuri, inobatwa nedura rePolyhexamhylene Buanidine. Mushure meizvozvo, iyo indekisi yekudzora yeiyo layer inoderera, uye iwo mwenje unoratidzwa nekona yemadhigiri makumi matanhatu. Kuchinja indekisi yePolyhexamwlene layer, pamwe nekuchinja kweiyo wavelength yeiyo yakaratidzwa yechiedza ichienderana neyekutanga zvinoenderana negero yekusangana.
Kubatsira kweiyo sensor inoreva chokwadi chekuti hakukonzeresa kusanzwisisika mune iyo indekisi yekudzora muPolymer Layer uye haina kurekodha huwandu hwemamwe magasi mumhepo, semuenzaniso nitrogen uye hydrogen. Mukuwedzera, zvinokwanisika kugadzirisa maitiro e electromagnic yezvinyorwa uye kuwana zvimwe zvinhu zvekushandisa, semuenzaniso, kuchinja mwero wekunyora mwenje uye nekudaro kuona kutarisisa kwakanyanya kwekabhoni diokixide.
"Panguva yebasa, takawana kudzidza kwehuwandu uye takawana kutsamira kweiyo indekisi yekudzora kweiyo Buguanidine polyhexets Isu takaratidza chokwadi che sensor tichishandisa ten tumplicate kuyerwa matanho. Isu timwe nguva imwe neimwe yasvika 50 PPM carbon dioxide kune sensor, uye zvakare yakasvibiswa ne nitrogen imba.
Ongororo yacho yakaratidza kuti sensor inoratidza kuiswa kweCarbon Dioxide nekanganiso yeN2, "akadaro Nikolai Kazansky, purofesa weDhipatimendi rehunyanzvi hweSamara University. Iyo yakakurudzirwa sensor yekugadziriswa inogona kushandiswa kuona mamwe magasi ane chepfu uchishandisa yakakodzera mashandiro emabasa.
