He kinoea kala ʻole a ʻala ʻole ka carbon dioxide. ʻO ia kekahi o nā mea nui o ka lewa. E like me ka mea nui o ka photosynthesis, pili pono ka ʻike o CARBON dioxide i ka pono photosynthetic o nā mea kanu, a hoʻoholo i ka ulu ʻana a me ka hoʻomohala ʻana, ka pae oʻo, ke kūpaʻa koʻikoʻi, ka maikaʻi a me ka hua o nā mea kanu. Akā ʻo ka nui o ia mea ʻaʻole e hoʻopuka wale i ka hopena ʻōmaʻomaʻo a me nā hopena ʻē aʻe, akā e pōʻino pū kekahi i ke olakino kanaka. Ma ka 0.3 pakeneka, ʻike ka poʻe i kahi ʻeha poʻo, a ma ka 4-5 pākēneka ke manaʻo nei lākou e ʻeha. ʻO ke kaiapuni i loko, ʻoi aku ka nui o nā lumi ea, ua hoʻopaʻa ʻia. Inā ʻaʻohe ventila no ka manawa lōʻihi, e piʻi mālie ka neʻe ʻana o ka carbon dioxide, he mea pōʻino i ke olakino kanaka. Wahi a ke kūlana o ka ea o loko i hoʻokō ʻia i ka makahiki 2003, ʻaʻole pono e ʻoi aku ka nui o ka waiwai maʻamau o ka hapa nui o ka awelika kalapona kalapona i kēlā me kēia lā ma mua o 0.1%.
Me ka hoʻomau mau ʻana o ka ʻepekema a me ka ʻenehana, ʻo ka hoʻonui nui ʻana o ka nohona o ka poʻe a me ka hoʻonui ʻana i ka nānā ʻana o ka poʻe i ka mālama ʻana i ke kaiapuni, ka nui o ka nānā ʻana a me ka mālama ʻana i ke kinoea carbon dioxide ua lilo i mea koi nui i ka ea, ka mahiʻai, ka lāʻau lapaʻau, kaʻa a me ka palekana o ke kaiapuni. .Hoʻohana nui ʻia nā sensor carbon dioxide i ka ʻoihana, ka mahiʻai, ka pale aupuni, ka lāʻau lapaʻau a me ke olakino, ka mālama ʻana i ke kaiapuni, aerospace a me nā māla ʻē aʻe.
Hoʻokomo ʻia ke kumu hana o ka sensor carbon dioxide ma lalo nei.
Loaʻa i kēlā me kēia mea waiwai kona ʻano ponoʻī o ka laina ʻālohilohi, a me nā kikoʻī absorption like, e like me nā molekala o ke kinoea carbon dioxide. ʻO ka haʻalulu lattice o nā mea seramika a me ka neʻe electron he hopena obstacle, piʻi ka mahana, hoʻoikaika ʻia ka haʻalulu lattice, hoʻonui ʻia ka amplitude, hoʻoikaika ʻia ka hana electron hindrance. E like me ke kinoea selective absorption theory, i ka wa e hui ai ka nalu o ka hawewe o ke kumu malamalama me ka hawewe absorption o ke kinoea, e hiki mai ana ka resonance absorption, a pili kona ikaika absorption i ka noonoo o ke kinoea. Hiki ke ana ʻia ka ʻike o ke kinoea ma ke ana ʻana i ka ikaika absorption o ke kukui.
I kēia manawa, nui nā ʻano o ka carbon dioxide sensor, me ka thermal conductivity type, densitometer type, radiation absorption type, uila conductivity type, chemical absorption type, electrochemical type, chromatography type, mass spectrum type, infrared optical type a pēlā aku.
Hoʻokumu ʻia ka mea ʻike kinoea carbon dioxide absorption infrared ma ke kumumanaʻo e ʻokoʻa ka spectrum absorption o ke kinoea me nā mea like ʻole. ʻO ka sensor carbon dioxide e ka hoʻokele kaʻa kaʻa kaʻa infrared i loko o kahi band infrared paʻa, ka absorption o ke kinoea ma lalo o ka hoʻāʻo ʻana, hoʻololi amplitude kukui infrared, hou ma o ka helu helu ʻana no ka hoʻololi ʻana i ka ʻike kinoea, ka hōʻailona o ka sensor ma hope o ke kānana ʻana, hoʻomaikaʻi ʻia a ʻO ka hōʻiliʻili ADC a me ka hoʻololi ʻana, ka hoʻokomo ʻana i ka microprocessor, ka ʻōnaehana microprocessor e like me ka mea i hōʻiliʻili ʻia e uku i ka mahana kūpono, ke kaomi, ka mahana, ke kaomi, ua helu hope i ka hoʻopuka ʻana o ka carbon dioxide density i kahi mea hōʻike ma lalo o ka hoʻāʻo. Loaʻa i ka nui o ka tunable diode laser absorption spectroscopy, photoacoustic spectroscopy, cavity enhancement spectroscopy a me non-spectral infrared spectroscopy. He nui nā pono o ka sensor infrared absorption, ke ʻano kiʻekiʻe, ka wikiwiki o ka nānā ʻana, ka paʻa maikaʻi, etc.
ʻO ka mea ʻike kinoea CARBON dioxide electrochemical kahi mea ʻike kemika e hoʻololi i ka ʻike (a i ʻole ka puʻe hapa) o ke kalapona dioxide i hōʻailona uila ma o ka hopena electrochemical. E like me ka ʻike ʻana o nā hōʻailona uila, ua hoʻokaʻawale ʻia ke ʻano electrochemical i ke ʻano hiki, ke ʻano o kēia manawa a me ke ʻano capacitance. E like me ke ʻano o ka electrolyte, aia nā electrolytes wai a me nā electrolytes paʻa. Mai ka makahiki 1970, ua hopohopo nui nā mea noiʻi electrolyte paʻa CARBON dioxide. ʻO ke kumu o ka electrolyte paʻa ʻo CARBON dioxide sensor ʻo ia ka mea hoʻonaninani kinoea e hana i nā ion i ka wā e hele ai i loko o ke kinoea, pēlā e hana ai i ka ikaika electromotive a me ke ana ʻana i ka ikaika electromotive i hiki ke ana i ka hapa leo o ke kinoea.
ʻO ka hoʻohana ʻana i nā ʻano hana wela like ʻole o CARBON dioxide a me nā kinoea ʻē aʻe ka mea ʻike kinoea carbon dioxide ʻo ia hoʻi ka mea mua i hoʻohana ʻia e ʻike i ka sensor carbon dioxide. Akā, haʻahaʻa kona naʻau.
ʻO ka nalu acoustic nalu (ʻike) kinoea sensor i loko o ka piezoelectric crystal coating kahi papa o ka adsorption koho o ke kinoea kinoea kino kiʻiʻoniʻoni, i ka wā e launa pū ai nā kiʻiʻoniʻoni kinoea me ke kinoea ma lalo o ka hoʻāʻo ʻana, e hana i ke kinoea sensitive film coating quality, character like viscoelasticity and ke hoʻololi i ka conductivity, e hoʻoheheʻe i ka ʻili o ka hawewe acoustic o ke aniani piezoelectric, e ʻike i ka neʻe ʻana o ke kinoea. ʻO ka mea ʻike kinoea acoustic wave (SAW) kahi ʻano mea ʻike makaʻala nui. Eia kekahi, hana ka quartz crystal microbalance gas sensor ma ke ʻano like me ka mea ʻike SAW, no laila pili pū nō ia i ka mea ʻike nui. ʻAʻohe koho i ke kinoea a i ʻole ka mahu, a ʻo kona koho ʻana ma ke ʻano he mea ʻike kemika e hilinaʻi wale ʻia i nā waiwai o nā mea uhi uhi.
Hoʻohana ka ʻenekini kalapona kalapona semiconductor i ka mea ʻike kinoea semiconductor e like me ka mea ʻike kinoea, a ʻo ka metal oxide semiconductor carbon dioxide sensor i loaʻa nā hiʻohiʻona o ka pane wikiwiki, ke kū ʻana o ke kaiapuni ikaika a me ke ʻano paʻa.
