Kupu Whakataki: Te Uaua o te Mātauranga Wai

I roto i ngā hanganga ahumahi o ēnei rā, ko te whakahaere i te kounga o te wai he mahi wehewehe i roto i te nama hangarau. Ko ngā tohunga i roto i ngā rāngai mai i te ahuwhenua tika ki te tukatuka matū kua roa e raru ana ki te kawenga whakahaere o te whakamahi i ngā pūoko maha, nui hei hopu i te kōtaha o tētahi tauira kotahi. Ko te whakawhirinaki ki ngā tirotiro motuhake mō te pH, te kawe hiko, me te tote ehara i te mea ka whakanui noa i te tapuwae tinana; ka whakanuia hoki ngā tohu o te rahunga, ā, ka uaua ake te tukutahi raraunga. I a tātou e anga atu ana ki tētahi heke mai e tautuhia ana e te "mātauranga wai" tūturu, me whai huarahi māmā te umanga ki te hopu tohu. Ka whakakorea e te RD-PETSTS-01 tēnei raruraru, ka whakakapi i te whiri o ngā taura ki tētahi otinga whakauru kotahi, mahi-teitei i hangaia mō ngā uauatanga o te umanga atamai.

Te Mana o te Rima: Te Whakaurunga Rangatira i roto i te Pūtaiao Kotahi

Ka whakakotahi te RD-PETSTS-01 i ngā tawhā telemetry matua e rima—te pH, te Aroturuki Hiko (EC), ngā Totoka Whakarewa Katoa (TDS), te Tote, me te Mahana—ki roto i tētahi taputapu kotahi e rite ana ki te rumaki. Mā tēnei whakaurunga ka hopukina ngā tohu raraunga katoa mai i te rōrahi wai kotahi i te wā kotahi, ka whakaratohia he whakaahua tika ake o ngā nekehanga otinga i ngā whakamātautau takitahi kua whakaritea. Ka tukuna e te pūoko he takai mahi pakari: pH mai i te 0–14, EC tae atu ki te 10,000us/cm, TDS tae atu ki te 5,000ppm, Tote i te 8ppt, me te awhe pāmahana o te 0–60℃. Mā te whakaiti i te utu taputapu me te whakangawari i te waea ki tētahi hononga waea-whā kotahi, ka taea e ngā kaiwhakahaere te:

"Tūturu, kia iti te utu, kia iti hoki te mahi."

Te Hangarau mō te "Whakararuraru Matatini"

He rongonui ngā taiao ahumahi pēnei i ngā whare whakakikorua hiko me ngā whare maimoatanga paru mō te haruru hiko ka taea te whakaiti i ngā tohu ngaohiko iti. Hei whakarite i te pumau o ngā raraunga, ka whakamahia e te RD-PETSTS-01 te tātari pūnga ā-tuaka ā-roto me te ātete 100M hei whakanui ake i te aukati whakauru. He kōwhiringa hangarau nui tēnei mō te pupuri i te pono o te tohu me te aukati i te ngoikore i runga i ngā taura ahumahi roa e rite ana ki ngā hanganga nui. Me ngā "wehewehenga e whā" me te whakatauranga ātete wai IP68, kua hangaia te pūoko hei ātete i te pokanoa o te pae me te tuku i ngā whakaurunga rerekētanga RS485 tika ki tō pūnaha kohikohi raraunga.

He Mea Nui te Rahi: Te Painga 42mm

Ko ngā here ā-tinana te arai matua ki te aroturuki pono-teitei i roto i ngā hanganga o nāianei. Ka arohia tēnei e te RD-PETSTS-01 me te roa kiato 202mm me te whānui o te tinana 42mm e whakawhāiti ana ki te pito 34mm. He mea hanga motuhake tēnei kōtaha whakawhāiti mō te whakatakoto ki roto i ngā "paipa iti" me ngā kōhao iti e kore e taea te uru ki ngā pūoko ahumahi paerewa. Nā te mea he "iti te rahi, he tino whakauru, [ā,] he ngāwari ki te kawe," e rua āna mahi: he taputapu pumau i roto i ngā paipa piri me te taputapu kawe mō te whakamātautau tere i roto i ngā whare kati kōtuhi ahuwhenua, i ngā pūnaha waikeri tāone rānei.

Hononga Maeneene mai i te Marae ki te Kapua

Ko te hononga te mea e huri ai te taputapu pūmārō hei pūnga IoT tūturu. Mā te whakamahi i te pūtake hiko DC 12~24V, ka whakawhitiwhiti kōrero te pūoko mā te atanga RS485 paerewa-ahumahi mā te whakamahi i te kawa Modbus-RTU (9600 baud rate). Mō ngā tohunga hangarau i te mara, ka tautoko te taputapu i te wāhitau whakapāho 0XFE, he mea tino haumaru mō te uiui i te wāhitau taketake mēnā kua warewarehia, kua whirihorahia rānei. He maeneene te whakaurunga; ka taea te whirihora i te pūoko mā te hononga USB-ki-RS485 mō te tatūnga taumata-PC me te hono atu ki ngā kaikohikohi ahokore e tautoko ana i te WIFI, GPRS, 4G, LoRa, LoRaWAN rānei. Mā tēnei ka taea te "Pūnaha Kohi Raraunga" katoa e rere ana i te telemetry wā-tūturu ki te pūmanawa tūmau kapua e ōrite ana mō te aroturuki mamao.

Te Tika Mā te Whakamaherehere Maha-Pūwāhi

Ko te pupuri i te tika o te taumata ahumahi—±0.1PH mō te waikawa me te ±1% FS mō te tote—me whai tikanga whakatikatika pakari. Ka tautoko te RD-PETSTS-01 i te whakatikatika tuarua e whakahaerehia ana e te kaiwhakamahi, e āhei ai te whakatikatika pai mā ngā rēhita Modbus. Ka taea e ngā kaiwhakahaere te mahi i te whakatikatika pH e toru-ira mā te whakamahi i ngā otinga paerewa (4.01, 6.86, me te 9.18) me te whakatika i te pari EC mā te whakamahi i te otinga paerewa ahumahi 1413us/cm. He mea nui tēnei taumata whakahaere matūriki hei pupuri i te tika o te pāmahana ±0.5℃ o te pūoko me te pumau ine whānui puta noa i tōna huringa ora, me te whakarite kia tutuki i ngā manawanui pakari o ngā rāngai rongoā me te tiaki taiao.

Whakamutunga: Te anga atu ki tētahi heke mai mō te wai, he māmā ake, he atamai ake

Ko te RD-PETSTS-01 e tohu ana i te nekehanga atu i te "whanuitanga o ngā pūoko" ki te hanganga tino whakauru, pakari hoki. Mā te whakaiti i ngā arai ā-tinana me te pūtea ki te aroturuki wai maha-tawhā, ka taea e tēnei taputapu tirotiro 5-i roto-i-te-1 ngā ahumahi te neke mai i te tauira tauhohe ki te whakahaere matatau, e whakahaerehia ana e ngā raraunga. I a koe e aromatawai ana i tō puranga aroturuki o nāianei, whakaarohia te utu whakahaere me te tātari o ō taputapu tirotiro o nāianei. E hia te nui o te whai huatanga huna ka taea e koe te wetewete mā te whakapai ake ki tētahi hoahoa "mātauranga wai" kua whakangāwari ake?
