I hurihia e au taku pūoko whakamutunga - nā reira i whakawhiti ahau ki te ōmata. Anei te mea i tūpono.
I tērā kōanga he iti noa iho taku waipuke i roto i taku papa o raro. Kāore he mea kino, engari he nui rawa ki te whakangaro i tētahi pouaka pūkete vinyl tawhito e hiahia ana ahau ki te whakamati mō ngā tau. Te tangata hara? He whakakā mānu māmā i roto i taku puna papu waipuke kua tāmia ki tētahi momo paru kiwikiwi — tērā pea he ranunga kohuke me ētahi atu mea i kitea ki roto i taua rua i roto i ngā tau. I mau te mānu ki te tūnga "whakararo", kāore i tīmata te pūnaha, a, ka oho ake ahau ki te kāpeti haukū me taua haunga.
Koia tērā te wā i tīmata ai ahau ki te āta whakaaro i te taumata wai.
Te Raru o ngā Whakakā Mānu (me te aha mātou e whakamahi tonu ai i a rātou)
Titiro, he māmā te utu o ngā whakakā mānu. Kei te kōrero ahau i te $3–$5 i Amazon, ā, he ngāwari noa iho ki te waea. Mō te tokomaha o ngā tāngata, koia te mutunga o te kōrerorero. Engari anei ngā mea kāore he tangata e kōrero ki a koe kia tōmuri rawa rā anō: ka tārewa. Ka hanga ngā kohuke ki runga i te tikanga hinge. Ka tipu te algae i runga i te tinana mānu mēnā kei te whakamahia e koe i roto i tētahi kura hydroponic, i tētahi mea whai matūkai rānei. He otaota iti — he wāhanga rau, he aho iti — ka mau ki raro i te mānu, ka pupuri ki raro. Ā, kāore koe e mōhio kia noho kē te wai ki te wāhi kāore e tika ana.
E toru ngā whakakā mānu i roto i te waru marama i mua i taku rawaka.
Ngā Pūoko Ultrasonic: Pai Ake, engari kāore i te tino tika
Ko taku nekehanga panuku ko tētahi kōwae ultrasonic HC-SR04 - te momo kei roto i ia kete tīmata Arduino. I whakatūria e au ki runga ake i taku puna, tohu iho ki te mata wai, ka tuhi i ētahi waehere hei ine i te tawhiti. I whakamahia... te nuinga o te wā.
Ko te raruraru ko ngā wāhi matapo. He iti rawa te tawhiti o ngā pūoko ultrasonic (i te nuinga o te wā tata ki te 2cm), ā, mēnā he pāpaku tō puna, he take tūturu tēnā. E uaua ana hoki rātau ki te whakatōpū i runga i te kanohi transducer, ā, i kite ahau ka pārekareka ngā pānui i te wā o te pāmahana - ka huri te tere o te oro i te pāmahana, ā, kāore taku tatūnga tōkarikari i te utu mō tēnā.
Mō te taumata whakapā kore i runga i tētahi kura nui — kī atu, He oko kohinga wai marangai 500 rita — he tino rawe te ultrasonic. Engari mō te haurapa taumata-pūwāhi pū i roto i tētahi kōpae iti, i tētahi puna wai rānei? I pēnei i te whakamahi i te rīpene ine hei tirotiro mēnā kei te tīari tētahi pata wai kotahi. Whakamate rawa, ā, kāore i te tika mō ngā mea e hiahiatia ana e au.
Haere Ōmata: Te Rūpahu W150-AH-PH
I muri i ētahi ruku wānanga pō, I tau ahau ki te pūoko taumata wai ōmata W150-AH-PH mai i tētahi kamupene ko Everlight. Tata ki te $8–$12 te utu i runga anō i te kaihoko — i whiwhi ahau i taku mai i tētahi kaihoko i AliExpress mō $9.50 kua tukua. Ehara i te pūoko tino pai rawa atu i reira, engari he tawhiti rawa atu i te $40–$60 i kitea e au i ētahi pae kaiwhakarato mahi.
Anei te mea e rerekē ai: kāore he wāhanga nekeneke. Kore. Ko te mutunga pakihi he koeko prisma pūataata me tētahi LED pōkākā me tētahi phototransistor i hiritia ki roto. Ina hau te aki, ka tāwhana ā-roto te rama IR i te mata prisma, ā, ka tuki ki te kaiwhiwhi. Ina pā te wai ki te pito, Ka huri te koki tāhapa — ka māturu te mārama ki roto i te wai, kaua e whakaata whakamuri — ā, ka pouri te kaiwhiwhi. Ka takahuri te huaputa.
He whakakā mārō tēnei. Kāore he mānu ki te tāmi, kāore he take ki te whakakino, kāore he mau pūkaha. Kua kōhuatia te mea katoa ki te epoxy waikore. Kua kōrurutia tonutia e au tōku mō te rima marama ināianei i roto i tētahi poka kōpae tērā pea ka mate tētahi whakakā mānu i roto i ngā wiki.
Ko tētahi atu i whakaarohia e au: Seeed Studio SEN020578
I mua i te tō i te keu i te W150, I titiro hoki ahau ki te pūoko taumata wai ōmata o Seeed Studio Grove (SEN020578, tata ki te $7–$9). Ka whakamahia e ia te mātāpono tāhapa ōrite, engari ka tae mai me te pūnaha tūhono 4-pin a Grove, he pai mēnā kei roto kē koe i te pūnaha pūnaha o Grove. Te whakawhitiwhiti: Tata ki te 50cm anake te taura, ā, he āhua nui ake te whare i te āhua o te W150. Mō taku āhuatanga whakatū poka kikī, i toa te āhua o te W150. Engari mō tētahi tatūnga hydroponics tēpu, tētahi hanga ā-Grove rānei, he kōwhiringa tino tika te kōwae Seeed.
Te Whakaaho Ana (He tino ngāwari)
E toru ngā pine o te W150: VCC, GND, me te PUTA. I honoa e au te VCC ki te 5V i taku Arduino Nano, GND ki te whenua, me te OUT ki te pine mamati 2 me te kume-ake ā-roto kua whakahohea. Ka kumea e te kōwae te raina ITI i te wā e kōruru ana te rūpahu. Koirā. Kāore he wae waho, kāore he ātete, kāore he kōhua tōkarikari. E whā meneti pea te roa o te mahi waea katoa.
Kotahi te mea ka whakahuatia e au: ko te kōwae i whiwhi ahau ko te taupēnga mamati. Ka tukuna hoki e ētahi kaihoko tētahi putanga tairitenga e hoatu ana ki a koe he awhe ngaohiko, kaua ko te tiketike/iti mā — he whaitake mēnā e hiahia ana koe ki te kite i ngā huringa taumata ā-rua, kaua ko te āhua mākū/maroke ā-rua. Mō taku tono papu sump, ko te matihiko tonu tāku i hiahia ai.
Te Waehere: kia māmā noa iho (me te Hopu Kotahi)
Ko te pānui taketake he mamati noa iho(SENSOR_PIN). Mēnā he ITI, kua mākū koe. Mēnā he TEITEI, kua maroke koe. Ka taea e te tīmatanga te tuhi i te arorau uho i roto i tana moe.
Engari — ā, he mea nui tēnei — kaua e whakaoho noa i tō papu i te wā tonu ka whiwhi koe i tētahi pānui ITI. Te pārekareka o ngā mata wai. Tītītī o ngā kōpae. Mēnā ka waea hāngai koe i tō papu ki te huaputa pūoko, Ka whiwhi koe i te paihikara tere ka pau tō tāpae, tērā pea ko tō mīhini papu hoki.
Anei te tinihanga whakaheke e whakamahia ana e au: Me pānui tonu te pūoko i te "mākū" mō te rua hēkona i mua i te whakahohe i te papu. E rua hēkona o te ruku motukore, ko te tikanga he huringa taumata tūturu, kāore he mea nui. I te taha takahuri, Ka katia e au te papu i te wā e pānui ana i te maroke - kāore he whakaheke i te taha maroke, nā te mea kāore au e hiahia kia maroke te papu me te wera rawa.
Tāutanga: Ko tāku i ako ai i te huarahi uaua
E rua ngā mea i ngau i ahau i te wā o te tāutanga kāore i whakahuatia e te rauraraunga:
Whakararuraru o te rā. I te tuatahi ka whakatūria e au te rapunga ki te tapa o runga o taku rua, e mārakerake ana ki tētahi matapihi o raro. I ngā ahiahi ātaahua, i rawaka te IR o te rā ki te tinihanga i te kaiwhiwhi i ētahi wā ki te whakaaro kua maroke te prism ahakoa i te kōruru. Te whakatika: I ararere ahau i tētahi wāhanga paipa PVC pango 1-inihi ki roto i te rua, ā, ka whakanohoia te pūoko ki roto. Kāore he take o te rā. Te utu tapeke o te PVC: mō $1.50 mai i te pātaka pūmārō.
Takotoranga whakatū. Ko te wā tuatahi i tāutatia e au, He iti noa iho taku tohu whakarunga i te rūpahu. I te hekenga o te taumata wai, Ka piri te pata ki raro o te prism, ā, ka pupuri i te pūoko e pānui ana i te "mākū" mō ētahi meneti anō - ko te tikanga ka whakaweto tōmuri te papu. Ehara i te mea nui i roto i taku tono, engari i roto i tētahi tatūnga tōtika e whai take ana. Whakatūngia whakapaetia, me te aki rānei e tohu whakararo ana. Ma te tō ā-papa e ūkui te pata.
inihua: E penapena moni ana koe?
Anei tētahi mea kāore au i tūmanako: i muri i taku tāutatanga i taku pūnaha pūoko me te tuhinga mō te inihua o taku kaipupuri kāinga, He iti noa iho taku whakahekenga utu mo taku utu. Āhua Katoa (taku kaiwhakarato) ka tukuna he whakahekenga utu "pūrere parenga" - ehara i te mea nui, mō 5% i te wāhanga o taku utu e pā ana ki te kapinga tūkino wai, e mahi ana ki te $30–$40 ia tau. Ehara i te mea huri ora, engari i utua e ia te pūoko me te Arduino i roto i te tau tuatahi. Ka rerekē tō maero mā te kaiwhakarato, engari he pai te pātai.
