Hiki ke loaʻa nā mea ʻike wela a me ka haʻahaʻa ma nā wahi āpau o ke ola. Hiki i kēia mau mea ʻike ke ana i ka mahu wai i ka lewa a me ka mahana o ka ʻāina. Akā, pehea lākou e hana ai, a he aha nā ʻano like ʻole?
1. He ahaNā mea ʻike wela a me ka haʻahaʻa？
Hoʻolālā ʻia kēia mau mea ʻike no nā ʻano noi like ʻole a hoʻohana ʻia e ana i ka haʻahaʻa a me ka mahana o ke kaiapuni.
Hana lākou i kēia ma ka ʻimi ʻana i ka nui o ka mahu wai i loko o ka lewa a puni ka ʻike. Hiki ke hui pū ʻia nā mea ʻokoʻa i loko o ke kinoea, me ka nitrogen, ka mahu wai, argon, etc.
No ka mea hiki i ka haʻahaʻa ke loaʻa ka hopena nui i nā kaʻina biolocal, kemika a me ke kino, pono ke ana ʻia a mālama ʻia i nā ʻoihana like ʻole, no laila, pono kēia mau mea ʻike e kōkua iā mākou.
2. Nā meaʻike wela a me ka haʻahaʻa
Pehea e hana ai nā mea ʻike wela a me ka haʻahaʻa?
ʻElua ala ʻokoʻa e hōʻiliʻili ai nā mea ʻike wela a me ka haʻahaʻa i ka ʻikepili a ana i ka haʻahaʻa a me ka mahana.
1. Hookahi ana anaka haʻahaʻa pili (ʻike pū ʻia ʻo RH)
2. ʻO kekahiana i ka haʻahaʻa haʻahaʻa (ʻike ʻia ʻo AH).
Hiki ke hoʻokaʻawale ʻia lākou ma muli o ko lākou nui. Hoʻohana ʻia nā mea ʻike liʻiliʻi no nā noi liʻiliʻi, ʻoiai hoʻohana mau ʻia nā mea ʻike nui no nā noi ʻoihana.
Hoʻopili ʻia kekahi o kēia mau mea ʻike i kahi microcontroller no ke ana koke ʻana i nā ʻikepili pili. Loaʻa i kēia mau mea naʻau he capacitive humidity sensing element a me kahi thermistor no ka ʻike ʻana i ka mahana ambient. ʻO kamea ʻike haʻahaʻaʻO ka element (capacitor) he ʻelua mau electrodes a ua hoʻohana ʻia ka substrate mālama ʻana ma ke ʻano he dielectric ma waena o kēia mau electrodes ʻelua. Ke hoʻololi ka pae haʻahaʻa, hoʻololi ka waiwai capacitance e like me ia. Aia kahi IC i hoʻohui ʻia i loko o ke kelepona e loaʻa ai ka ʻikepili ana a me ka hana ʻana i nā waiwai kūʻē e loli ma muli o nā loli o ka haʻahaʻa a hoʻololi i ka ʻikepili i ke ʻano kikohoʻe no ka mea heluhelu.
ʻO ka wehewehe maʻalahi loa ʻo ia ka hoʻohana ʻana o kēia mau mea ʻike i kahi thermistor coefficient wela maikaʻi ʻole e ana i ka mahana. Ke piʻi aʻe ka mahana ambient, hoʻemi ka mea i kona waiwai kū'ē.
Kahi mea hou aʻe,aia nā mea ʻike wela a me ka haʻahaʻa me nā hōʻike i hoʻolālā ʻia e hāʻawi i nā hōʻike ʻike o ka haʻahaʻa a me ka mahana a hana i kahi ʻike maikaʻi loa no ka mea hoʻohana e hoʻohana ana i ia mau ʻike. No ka laʻana, ʻo 802c a me 802p ka mahana a me ka haʻahaʻa me ka hōʻike, kūpono nā mea ʻike no ka wā e hele ai ʻoe i waho a pono e nānā i ka mahana a me ka haʻahaʻa o kahi. Loaʻa iā lākou ka pololei nui!
3. Ka pololei onā ʻenehana wela a me ka haʻahaʻa
ʻOkoʻa ka pololei o nā mea ʻike wela a me ka haʻahaʻa.
No ka laʻana, ʻo ka HT802 series temperature and humidity sensors he ±2% pololei a hiki ke ana i ka 80% humidity.
ʻO kēia ke kumu i hoʻohanaʻia ai nā meaʻike kiʻekiʻe no nāʻoihana e pili ana i ka mālamaʻana i ka mahana a me ka haʻahaʻa ma kekahi pae, no ka mea, hāʻawi lākou i kaʻikepili pololei a hilinaʻi.
No ka laʻana, pono nā ʻāpana meteorological a me ka ʻepekema i nā mea ʻike me ke ana haʻahaʻa piha mai ka zero a 100% RH. ʻAʻole pono nā wahi ʻē aʻe i ka laulā piha no kā lākou noi noi. Pono ʻoe e ʻike ʻoi aku ka nui o nā mea ʻike me nā pae kiʻekiʻe ma mua o nā mea ʻike me nā pae ana haʻahaʻa.
ʻO kaHT802ʻO ka pūnāwai wela a me ka haʻahaʻa haʻahaʻa a mākou i ʻōlelo ai ma mua e kūpono no nā ʻano noi like ʻole a ʻoi aku ke kumukūʻai ma mua o nā mea i hoʻohana ʻia no nā noi ʻoi aku ka maʻalahi. Inā makemake ʻoe i ka pololei ʻoi aʻe akā ʻaʻole loaʻa kahi kālā nui.
4. Haʻahaʻa a me ka wela Sensor Applications
E like me kā mākou i ʻōlelo ai ma luna nei, hiki ke loaʻa kēia mau mea ʻike ma nā polokalamu he nui, a loaʻa iā lākou nā ʻano noi like ʻole!
Hiki iā lākou ke kōkua i nā poʻe maʻi me nā pilikia hanu ma ka ʻae ʻana iā lākou e mālama i ka haʻahaʻa a me ka mahana o ka wahi i kahi pae maikaʻi loa.
1. No ka wānana ʻana i ke ʻano o ke anā, hoʻohana pū nā keʻena hoʻokele i kēia mau mea ʻike.
2. Hiki iā lākou ke hoʻohana no ka hoʻomehana a me ka ea, a me nā ʻōnaehana ea.
3. Hiki ke hoʻohana ʻia kēia mau mea ʻike i loko o nā hale ʻōmaʻomaʻo kahi e pono e nānā pinepine ʻia nā waiwai haʻahaʻa.
4. Hiki i nā hale hōʻikeʻike ke pōmaikaʻi mai ia mau mea, no ka mea, ʻo ia nā wahi e mālama ʻia ai nā mea kiʻi a me nā mea ma lalo o kekahi mau kūlana.
ʻO ka hope, Pehea wau e koho ai i kahi Sensor Temperature a Humidity kūpono?
Aia kekahi mau kikoʻī koʻikoʻi āu e pono ai e noʻonoʻo i ke koho ʻana i kēia huahana. Aia kēia me:
a. pololei;
b.Hiki hou.
c.Paʻa lōʻihi;
d.Hiki ke hoololi;
e.Hiki ke ho'ōla mai ka condensation;
f.Ke kū'ē i nā mea haumia kino a me nā kemika;
HENGKO'O nā mea ma'amau, hana ki'eki'e o ka 'oihana wela a me ka ha'aha'a ua kūpono ia no nā wahi 'oihana pa'akikī.
Hoʻohana ka huahana i nā mea ʻike kiʻekiʻe RHT me ka pololei kiʻekiʻe a me ka ikaika anti-interference ikaika, e hōʻoia ana i ka hana ana kiʻekiʻe.
ʻO nā ʻenehana wela a me ka haʻahaʻa haʻahaʻa he kūpaʻa lōʻihi ka lōʻihi, haʻahaʻa haʻahaʻa, kūpaʻa kiʻekiʻe i ka pollution kemika, a me ka hoʻihoʻi hou.
Loaʻa nā nīnau a makemake e ʻike i nā kikoʻī hou aku no ka nānā ʻana i ka haʻahaʻa ma lalo o nā kūlana ʻino, e ʻoluʻolu e kelepona iā mākou i kēia manawa.
Hiki iā ʻoeE hoʻouna mai iā mākou i ka leka uilaE like me ka hahai pololei ʻana:ka@hengko.com
E hoʻihoʻi mākou me nā hola 24, mahalo no kou hoʻomanawanui!
E hoʻouna i kāu leka iā mākou:
