Pehea lā e hiki ai iā kākou ke ana i kahi mea i ʻike ʻole ʻia, i hui pū ʻia me kahi mea hiki ʻole iā kākou ke ola me ka ʻole? Aia kēia nīnau ma ke kikowaena o ka lawelawe ʻana i kā kākou waiwai makamae loa: ka wai. No ka loaʻa ʻana o ka pane, ua nānā au i ka manual ʻenehana o kahi mea hana kūikawā, ʻo ia ka sensor RD-WDCO2, e ana ana i ke kalapona ʻokikene i hoʻoheheʻe ʻia. ʻO kaʻu i loaʻa ai, ʻaʻole ia he papa inoa o nā kikoʻī akā he moʻolelo o ka ʻenekinia akamai a me ka paʻakikī huna. Hōʻike kēia ʻatikala i kekahi o nā ʻike kupaianaha a kupaianaha loa i loko o kēlā manual, e hōʻike ana i ke akamai o ka mālama ʻana i ke ao holoʻokoʻa i ʻike ʻole ʻia i loko o hoʻokahi kulu wai.
ʻIke kēia sensor i ka CO2 me ka mālamalama infrared.
Ma kahi o ka hopena kemika a i ʻole kahi probe kino, hoʻohana kēia sensor i kahi ala optical nani. Wahi a Manual ua "hoʻokumu ʻia kā lākou ʻenehana ma ke kumumanaʻo absorption infrared NDIR," no laila ʻo ia hoʻi ke hoʻohana nei lākou i ka mālamalama infrared non-dispersive e ʻike ai inā he mau molekala CO2 a puni.
No ka hoʻokō ʻana i kēlā pae o ka pololei, pono ia e hoʻopuka i kahi ʻano kukui ʻoi aku ka akamai. Loaʻa iā ia kahi "lua optical i hoʻopaʻa ʻia, kumu kukui i lawe ʻia mai a me ka mea ʻike kahawai pālua." Hiki i kēia ʻano hoʻonohonoho ke "hoʻomaopopo i ka uku kuhikuhi o nā ala optical pālua i ka lewa," ʻo ia hoʻi, hiki i ka sensor ke hoʻomau mau iā ia iho i ka calibrated a hāʻawi i nā heluhelu pololei i nā manawa a pau, ʻaʻole ma muli o ka nui o ka oxygen. A maikaʻi loa ka hopena: ʻo ka pololei he ± (20PPM + 5% heluhelu), a ʻo ka manawa pane he emi ma mua o 20 kekona. Pane nani: e hoʻohana ana i kahi kala kukui e helu ai i ka helu o nā molekala kinoea kala ʻole i hoʻoheheʻe ʻia i loko o ka wai.
1. He mea paʻakikī loa ia a hana ʻia no nā hana haumia.
ʻOiai he mea hana optical ʻenehana kiʻekiʻe, ua hana ʻia ʻo RD-WDCO2 no ke ao maoli. Ua ʻōlelo ʻia kona "ʻano hana pale wai ʻokoʻa" hiki ke hoʻokaʻawale a hoʻomaʻemaʻe maʻalahi. He mea nui ka mālama pono ʻana no kahi mea hana e hiki ke hoʻokomo ʻia i loko o nā pahu mahiʻai iʻa a i ʻole ke nānā ʻana i ka wai kahe.
Ua helu kūhelu ʻia me IP68, ʻo ia hoʻi, ʻo ia ka mea i pale nui ʻia mai ka lepo a hiki ke hoʻoluʻu ʻia i loko o ka wai no ka manawa lōʻihi. A he hōʻike hou aʻe ia o ka ikaika o kēia no ka mea hiki iā ia ke hana ma nā ʻano mahana like ʻole, mai ke anuanu e like me minus 20 degere a i ka wela e like me 60 degere Celsius, no laila e maikaʻi wale nō ia i loko o kahi kahawai anuanu a i ʻole kahi pahu ʻoihana mahana. Ua ʻōlelo maikaʻi ʻia ke akeakamai hoʻolālā e kahi laina mai ka manual.
He māmā ka Shell a maʻalahi hoʻi e hoʻouka ma kahi.
A hoʻohui ia i kahi ʻōnaehana loko palupalu me kahi waho ikaika e maʻalahi i ka poʻe e hoʻohana. ʻO ia hoʻi, ʻike lākou i ka paʻakikī o ia mea ma waho ma nā wahi i koʻikoʻi ai kēia ʻano ʻike - e like me nā mahi iʻa a i ʻole ka nānā ʻana i ke kūlohelohe.
2. ʻAʻole wale nā mea i loko o ka wai e ana ʻia.
ʻO ka mea kū'ē loa aʻu i ʻike ai, ʻo ia ka hiki i ka "Water Dissolved CO2 sensor" ke hana me nā mea ʻē aʻe ma mua o ka wai. Ua ʻike ʻia ua hōʻike ka manual he mau hiki ke hana pālua maikaʻi loa ia e ʻoi aku ka pono ma mua o ka mea i kapa ʻia.
Wahi a ke kumu, hiki ke hoʻohana ʻia ʻo RD-WDCO2 e ana i ka nui o ka CO2 i hoʻoheheʻe ʻia i loko o ka wai, a hiki nō hoʻi ke hoʻohana ʻia e nānā i ka pae o ka CO2 i nā kūlana wela a me ka pulu.
A ʻo kēia ʻano hana maʻalahi e lilo ia i mea hana pono ma nā ʻano wahi like ʻole. Hiki ke hoʻohana ʻia e like me ka mea i manaʻo ʻia no ka "Aquaculture" a me ka "Water Quality Monitoring", akā maikaʻi nō hoʻi ia no ka "Environmental Monitoring of Agricultural Greenhouses" no ka mea hiki i ke kiʻekiʻe o ka makū ke hoʻolilo iā ia i mea paʻakikī no nā ʻano mea ʻike CO2 ʻē aʻe.
4. Kamaʻilio ia me kahi ʻōlelo kikohoʻe paʻakikī
He mea ʻole kahi sensor inā ʻaʻole hiki iā ia ke kaʻana like i kāna mea i loaʻa. ʻAʻole wale ʻo RD-WDCO2 e hōʻike ana i kahi helu, ke kamaʻilio nei ia me nā mīkini like ʻole ma ka hoʻohana ʻana i nā ʻano kamaʻilio kamepiula he nui (nā ʻōlelo kikohoʻe) i hiki iā ia ke haʻi i nā mea hana ʻē aʻe i ka nui o ka CO2. Kākoʻo ia i kahi ākea o nā hōʻailona hoʻopuka a me nā protocols e like me RS485, UART, IIC.
ʻAʻole kēia he leka uila maʻamau. I mea e loaʻa ai kahi heluhelu me ke kaʻina hana MODBUS maʻamau ma o RS485, pono i kahi kamepiula ke hoʻouna i kahi kaula kauoha kikoʻī ma ke ʻano hexadecimal. No ka laʻana, no ke noi ʻana i ka sensor #32 no kāna heluhelu CO2 o kēia manawa, e hoʻouna ka mea hoʻokipa i kēia leka i hoʻopili ʻia:
20 03 00 00 00 01 82 BB
A e pane mai ka sensor me kāna leka pohihihi ponoʻī nona ka ʻike e pono ai:
20 03 02 01 AB 44 6C
Ma kēia pane, ʻo ka ʻike koʻikoʻi ʻo 01AB. ʻO kēia ka nui o ka CO2 ma ke ʻano hex, ʻo ia hoʻi he 427ppm ma nā decimals. ʻO kēia mau kamaʻilio mālie a malū ke kumu nui o ka pilina ma waena o ke ao a puni mākou a me nā kamepiula e kiaʻi ana iā ia, e hoʻololi ana i nā helu maʻalahi mai nā mea ʻike i ka ʻike pono e hiki ai iā mākou ke hoʻohana.
Hopena: He Akamai Huna i loko o ka ʻenehana o kēlā me kēia lā
ʻO ka nānā hohonu ʻana i kahi manual loea e hōʻike ana ʻoiai ka mea i ʻike ʻia he mea liʻiliʻi he mea kupanaha ia o nā ʻano ʻenekinia like ʻole. Hoʻokahi sensor me nā optics kiʻekiʻe no ka ʻike ʻana i kahi kinoea ʻike ʻole ʻia, kahi hoʻolālā kino ikaika e kū i nā kūlana paʻakikī, a me nā lula kikohoʻe paʻakikī no ka kaʻana like ʻana i kāna mea i ʻike ai. He hoʻomanaʻo ikaika ia ma hope o nā ʻikepili āpau e holo nei i ko kākou honua, aia nā hopena ʻenehana nani a paʻa.
A ʻo ia ka mea e noʻonoʻo ai ʻoe: he aha hou aʻe kēia mau mea hoʻohaʻahaʻa e hopu nei me ka ʻike ʻole ʻia, e hoʻokele ana i nā ʻōnaehana a mākou e hilinaʻi nei me ka ʻike ʻole ʻia e mākou?
Hiki iā mākou ke hāʻawi i nā ʻano hoʻonā like ʻole no
1. Mīkini lima no ka maikaʻi o ka wai me nā palena he nui
2. ʻŌnaehana Buoy lana no ka maikaʻi o ka wai me nā palena he nui
3. Palaki hoʻomaʻemaʻe ʻakomi no ka mea ʻike wai multi-parameter
4. Hoʻonohonoho piha o nā kikowaena a me ka module uea ʻole polokalamu, kākoʻo iā RS485 GPRS /4g/WIFI/LORA/LORAWAN
No nā mea ʻike wai hou aku
