Carbon dioxide igasi risina ruvara uye risinganhuhwi. Icho chimwe chezvikamu zvakakosha zvemhepo. Sezvinoita reactant yephotosynthesis, kusangana kweCARBON dioxide kwakanangana neiyo photosynthetic kunyatsoshanda kwezvirimwa, uye inosarudza kukura uye kukura, danho rekukura, kusagadzikana kusagadzikana, kunaka uye goho rezvirimwa. Asi yakawandisa haingoburitse greenhouse effect uye mamwe mhedzisiro, asiwo inokuvadza hutano hwevanhu. Pa 0.3 muzana, vanhu vanonzwa musoro unooneka, uye pa4-5 muzana vanonzwa dzungu. Indoor environment, kunyanya mumakamuri ane air-conditioned, inenge yakavharwa. Kana pasina kufefetera kwenguva yakareba, kusanganiswa kwekabhoni dioxide kunowedzera zvishoma nezvishoma, izvo zvinokuvadza hutano hwevanhu. Zvinoenderana neyakajairwa mukati memhepo yemhando yemhepo yakaitwa muna 2003, kukosha kwakajairwa kwevhoriyamu chikamu cheavhareji zuva nezuva kabhoni dhaikisai yemukati haifanire kudarika 0.1%.
Nekuenderera mberi nekuvandudzwa kwesainzi uye tekinoroji, kuwedzera kuri kuita kuvandudzwa kwehupenyu hwevanhu uye kuwedzera kwekutarisa kwevanhu kuchengetedza kwezvakatipoteredza, kutarisisa kwehuwandu uye kutonga kwekabhoni dioxide gasi kwave kuwedzera kudiwa mumhepo inofefetera, kurima, kurapwa, mota nekuchengetedzwa kwezvakatipoteredza. .Carbon dioxide sensors anoshandiswa zvakanyanya muindasitiri, kurima, kudzivirira kwenyika, kurapwa uye hutano, kuchengetedza kwezvakatipoteredza, aerospace uye mamwe minda.
Iyo yekushanda nheyo yecarbon dioxide sensor inounzwa pazasi.
Chinhu chega chega chine hunhu hwayo hunopenya-mutsara spectrum, uye zvakafanana absorption spectra, sezvinoita mamorekuru ecarbon dioxide gasi. Iyo lattice vibration yezvinhu zveceramic uye kufamba kwe electron kune chipingamupinyi, tembiricha inokwira, iyo lattice vibration inosimbiswa, amplitude inowedzerwa, chipingamupinyi maelectron chiito chinosimbiswa. Zvinoenderana neiyo gasi inosarudza absorption theory, kana yavelength yekubuda kwechiedza sosi ichipindirana neabsorption wavelength yegasi, resonance absorption ichaitika, uye kunyura kwayo kunoenderana nekuwanda kwegasi. Kuwanda kwegasi kunogona kuyerwa nekuyera kunyura kwechiedza.
Parizvino, kune akawanda marudzi ecarbon dioxide sensors, anosanganisira thermal conductivity type, densitometer type, radiation absorption type, magetsi conductivity type, chemical absorption type, electrochemical type, chromatography type, mass spectrum type, infrared optical type nezvimwewo.
Infrared absorption carbon dioxide gas sensor inobva pamusimboti wekuti kunyura kwegasi kunosiyana nezvinhu zvakasiyana. Carbon dioxide sensor ne infrared mwenje mutyairi wedunhu kudzora mukati meyakagadziriswa bhendi infrared, kunyura kwegasi pasi pekuyedzwa, infrared mwenje amplitude shanduko, zvakare kuburikidza necheki kuverenga kwekuchinja kwegasi, iyo sensor inobuda chiratidzo mushure mekusefa, yakagadziridzwa kugadzirisa uye. ADC kuunganidza uye kutendeuka, iyo yekupinda kune microprocessor, iyo microprocessor system zvinoenderana neyakaunganidzwa inotsiva inoenderana tembiricha, kudzvanywa, tembiricha, kudzvanywa, pakupedzisira yakaverengera iyo kabhoni dhisiki density yakabuda kune yekuratidzira mudziyo uri muyedzo. Iyo inonyanya kusanganisira tunable diode laser absorption spectroscopy, photoacoustic spectroscopy, cavity yekusimudzira spectroscopy uye isiri-spectral infrared spectroscopy. Infrared absorption sensor ine akawanda mabhenefiti, yakanyanya kunzwa, kukurumidza kuongororwa kumhanya, kugadzikana kwakanaka, nezvimwe.
Electrochemical CARBON dioxide gas sensor ikemikari sensor inoshandura kusungirirwa (kana kuti chikamu chekumanikidza) kwekabhoni dhaikisaidhi kuita chiratidzo chemagetsi kuburikidza ne electrochemical reaction. Zvinoenderana nekuonekwa kwemasaini emagetsi, iyo electrochemical mhando yakakamurwa kuva inogona mhando, yazvino mhando uye capacitance mhando. Maererano nechimiro che electrolyte, pane mvura electrolytes uye yakasimba electrolytes. Kubva kuma1970, yakasimba electrolyte CARBON dioxide sensors ave achinetseka zvakanyanya nevatsvakurudzi. Musimboti weiyo yakasimba electrolyte CARBON dioxide sensor ndeyekuti gasi-sensitive material inogadzira maion kana ichipfuura nepakati pegasi, nokudaro ichigadzira electromotive simba uye kuyera electromotive simba kuitira kuyera vhoriyamu chikamu chegasi.
Kuita kushandiswa kweyakasiyana kupisa conductivity yeCARBON dioxide uye mamwe magasi carbon dioxide gas sensor ndiyo yekutanga kushandiswa kuona carbon dioxide sensor. Asi kunzwa kwayo kwakaderera.
Surface acoustic wave (saw) gasi sensor mune piezoelectric crystal inoputira dhizaini yekusarudza adsorption yegasi rinonzwa firimu, kana gasi rinonzwa firimu richibatana negasi pasi pekuyedzwa, gadzira gasi rinonzwa kuvharika kwemhando yemhando, hunhu hwakadai seviscoelasticity uye. conductivity shanduko, inokonzeresa iyo yepamusoro acoustic wave frequency yepiezoelectric crystal kuti ikukurwe, kuona kuungana kwegasi. Iyo yepamusoro acoustic wave (SAW) gasi sensor imhando yehuremu sensor sensor. Uye zvakare, iyo quartz crystal microbalance gasi sensor inoshanda pane yakafanana musimboti kune iyo SAW sensor, saka zvakare ndeyeyakawanda inonzwa sensor. Iyo mass sensitive sensor pachayo haina kusarudzwa kune gasi kana mhute, uye kusarudza kwayo sekemikari sensor inongoenderana nemaitiro epamusoro pekuvhara zvinhu.
Iyo semiconductor carbon dioxide gas sensor INOSHANDISA iyo semiconductor gas sensor se sensor gas, uye metal oxide semiconductor carbon dioxide gas sensor ine maitiro ekukurumidza kupindura, kupikisa kwakasimba kwezvakatipoteredza uye chimiro chakagadzikana.
