He mea koʻikoʻi ka ʻike ʻana i ka haʻahaʻa a me ka mahana, ʻoi aku hoʻi i nā hoʻoilo paʻakikī a mākou e ʻike nei i kēia manawa.He mea nui ia ʻaʻole wale i ke ola o kēlā me kēia lā, akā i ka ʻoihana hana.No ka laʻana, ke hoʻokomo pono ʻia a hoʻohana ʻia nā mea hoʻoheheʻe haʻahaʻa, hiki i nā ʻōnaehana automation ke hoʻoholo i ka wā e maloʻo ai ka ea a pulu paha no ka hōʻoluʻolu.
Ka mua, ʻike wela
Hoʻohana ʻia nā mea ʻike wela e hoʻoholo i ka nui o ka wela a i ʻole ke anu i hana ʻia e kekahi mea a ʻōnaehana.Hiki iā ia ke ʻike / ʻike i kekahi hoʻololi kino i ka mahana a me nā hōʻailona analog a i ʻole nā hōʻailona kikohoʻe.Hāʻule nā mea ʻike wela i ʻelua ʻāpana: Pono nā mea ʻike wela e pili ana i ke kino me ka mea e ʻike ʻia a nānā i nā loli wela ma o ka lawe ʻana.Hoʻopili nā mea ʻike wela e nānā i nā loli wela ma o ka convection a me ka radiation.
Ka lua,mea ʻike haʻahaʻa
ʻO ka haʻahaʻa ka nui o ka mahu wai ma ka lewa.He hopena ka nui o ka mahu wai i ka lewa i ka hōʻoluʻolu kanaka a me nā ʻano hana ʻoihana like ʻole.Hoʻopilikia pū ka mahu wai i nā ʻano hana kino, kemika a me ke olaola.Hana nā mea ʻike haʻahaʻa ma ka ʻike ʻana i nā loli i ke au uila a i ʻole ka mahana o ka ea.ʻEkolu ʻano kumu o nā mea ʻike haʻahaʻa: capacitive, resistive a me ka wela.E nānā mau kēlā me kēia ʻano ʻekolu i nā loli liʻiliʻi i ka lewa e helu i ka haʻahaʻa o ka ea.
Hoʻoholo ka mea ʻike haʻahaʻa capacitive i ka haʻahaʻa pili ma ka hoʻopaʻa ʻana i kahi ʻāpana metala oxide ma waena o nā electrodes ʻelua.ʻOkoʻa ka mana uila o nā ʻokikene metala me ka haʻahaʻa pili o ka lewa a puni.ʻO nā noi nui ʻo ka wā, kalepa a me ka ʻoihana.Hoʻohana nā mea ʻike haʻahaʻa pale i nā ion i loko o nā paʻakai e ana i ka impedance uila o nā mana.Hoʻololi ka pale electrode ma nā ʻaoʻao ʻelua o ka paʻakai me ka haʻahaʻa.ʻElua mau mea ʻike wela e hana i ka uila ma muli o ka haʻahaʻa o ka ea a puni.Hoʻopaʻa ʻia kekahi mea ʻike i ka nitrogen maloʻo, a ʻo kekahi e ʻike ʻia i ka ea ambient.Hōʻike ka ʻokoʻa ma waena o kēia mau waiwai ʻelua i ka haʻahaʻa pili.
ʻO ka mea ʻike haʻahaʻa kahi mea uila e ʻike i ka haʻahaʻa i loko o ke kaiapuni a hoʻololi iā ia i hōʻailona uila.Hiki mai nā mea ʻike haʻahaʻa i nā ʻano nui a me nā hoʻonohonoho;Hoʻohui ʻia kekahi i loko o nā mea paʻa lima, e like me nā smartphones, aʻo nā mea ʻē aʻe i hoʻohui ʻia i loko o nā ʻōnaehana hoʻokomo nui, e like me nā ʻōnaehana nānā ʻana i ka maikaʻi o ka ea.ʻo kahi laʻana, Hengko wela a me ka haʻahaʻa transmitters hoʻohana nui ʻia makameteorological, lāʻau lapaʻau, automotive a me nā ʻoihana HVAC a me nā ʻoihana hana.Hiki ke hōʻoia i ke ana pololei ʻana ma nā ʻano ʻano ʻino a pau.
ʻO ke kolu, ke ʻano helu
Hoʻokaʻawale ʻia nā mea ʻike haʻahaʻa i ka haʻahaʻa pili (RH) a me nā sensor haʻahaʻa piha (AH) e like me ke ʻano i hoʻohana ʻia no ka helu ʻana i ka haʻahaʻa.Hoʻoholo ʻia nā waiwai haʻahaʻa pili ma ka hoʻohālikelike ʻana i kahi heluhelu haʻahaʻa manawa maoli ma kahi mahana i hāʻawi ʻia me ka haʻahaʻa kiʻekiʻe o ka ea i kēlā mahana.No laila, pono e ana ka ʻenekini pili i ka mahana e helu ai i ka haʻahaʻa pili.Hoʻoholo kūʻokoʻa ka haʻahaʻa haʻahaʻa, ma ka ʻokoʻa.
ʻO ka lua, ka hoʻohana ʻana i nā sensor
Loaʻa i nā mea ʻike wela nā noi kūpono ʻole, ʻoiai ua hoʻohana ʻia lākou i nā ʻano huahana lapaʻau like ʻole, me nā mea hoʻonaninani magnetic resonance imaging (MRI) a me nā mea nānā ultrasound portable.Hoʻohana ʻia nā mea ʻike wela i nā ʻano mea hana like ʻole i loko o ko mākou mau hale, mai nā pahu hau a me nā pahu hau a hiki i nā kapuahi a me nā umu e hōʻoia ai ua wela lākou i ka wela kūpono no ka kuke ʻana, nā kukui ea/heater.Hoʻohana ʻia nā mea hoʻoili pākaukau maʻamau iā lākou e pale i ka hoʻonui ʻana a i ʻole ka hoʻokuʻu ʻana i ka pākaukau ma muli o kona mahana.
ʻOiai ʻaʻole paha e hoʻohana ʻia ka ʻili ʻaila no nā mea ʻike wela, pono lākou e hōʻoia i ka palekana a me ka maikaʻi o ka lawe ʻana i ka ʻaila.Aia ka ʻaila ʻaila ma kona hopena e hoʻomaopopo i nā limahana i ka wā e pono ai e hoʻōki i ka wili ʻana, no ka mea ke wela loa (no ka mea e hoʻomau mau ana i ka wili ʻana i ka lepo), hiki ke wela loa a haki.
Hoʻokumu ʻia ka mea ʻike wela i ka radiator o ke kaʻa.He mea koʻikoʻi kēia, no ka mea ke hiki i ka wai e kahe ana ma ka mīkini kaʻa i nā wela kiʻekiʻe ʻole, e makaʻala lākou iā ʻoe, inā ʻoi aku ka nui, hiki ke hoʻopau i ka ʻenekini, a me ke kaʻa o ke ea /.Ma ka hoʻololi ʻana i nā ʻāpana e like me ka mahana, ua pale maikaʻi ʻia kēia kūlana me ka ʻole o ka waiho ʻana i ka mea hoʻokele i ka pōʻino.
Pono nā ʻōnaehana HVAC i nā ana wela e kōkua i ka mālama ʻana i ka wela maikaʻi loa i loko o kahi lumi a hale paha.Pono nā mea ʻike wela ma kahi kokoke i kēlā me kēia ʻāpana ea a me nā ʻōnaehana ma nā hale a me nā keʻena.Hiki iā lākou ke hoʻohana ʻia e ʻike i nā leaks ma ka ʻike ʻana i nā anomalies wela i manaʻo ʻole ʻia.
Ke hilinaʻi nei ka ikehu hou i nā mea ʻike wela e holo pono.ʻO nā paila wela o ka lā, nā makani makani, nā noi hoʻohūhū biomass a me nā kumu wela o ka honua ke hilinaʻi nei i ka hoʻoponopono wela a me ke ana.
ʻO ka lima, ka hoʻoponopono pololei
No ka hoʻoholo ʻana i ka pololei o ka sensor, hoʻohālikelike ʻia nā waiwai i loaʻa me ka maʻamau kuhikuhi.No ka hōʻoia ʻana i ka pololei o nā mea ʻike haʻahaʻa, ua hana mākou i nā maʻamau me ka hoʻohana ʻana i kahi ala "paʻakai paʻakai".I ka pōkole, ke hoʻoheheʻe ʻia kekahi mau paʻakai (ionic compound e like me ka paʻakai papaʻaina a i ʻole ka potassium chloride) i ka wai, hana lākou i kahi ea o ka haʻahaʻa i ʻike ʻia.
Hoʻohana ʻia kēia mau mea kemika no ka hana ʻana i kahi microenvironment me kahi pākēneka i ʻike ʻia o ka haʻahaʻa pili (RH) (ke kūlana kuhikuhi), a laila heluhelu ʻia e kahi mea ʻike.ʻOi aku ka pololei, e hoʻomākaukau mākou i ka hopena i loko o ka pahu i hoʻopaʻa ʻia e paʻa i ka lewa, a laila kau i ka sensor pili i loko o ka pahu i hoʻopaʻa ʻia.Ma hope o kēlā, heluhelu pinepine ʻia ka sensor a hoʻopaʻa ʻia nā waiwai.
Hiki iā mākou ke hoʻomohala i nā profiles no ka sensor ma lalo o ka hoʻāʻo ʻana ma o ka hana hou ʻana i kēia kaʻina hana me nā paʻakai like ʻole, e hoʻopuka ana kēlā me kēia mea i ka haʻahaʻa pili like ʻole.No ka mea, ʻike mākou i ka haʻahaʻa pili o kēlā me kēia microenvironment, hiki iā mākou ke hoʻohālikelikeka mea ikeHeluhelu me kēlā mau waiwai i ʻike ʻia e hoʻoholo i ka pololei o ka mea ʻike.
Inā nui ka hoʻokaʻawale ʻana akā ʻaʻole hiki ke hoʻopau ʻia, hiki iā mākou ke hoʻomaikaʻi i ka pololei o ke ana ma o ka hoʻohana ʻana i ke kaʻina hana calibration makemakika i ka polokalamu.
