I whakawhitia e au aku whakakā mānu mō ngā pūoko taumata ultrasonic — e rua tau, Kotahi Tata ki te Waipuke, Kore Tatarahapa
Ko te kura i tata ngau i a au e noho ana i te taha o taku wharau — 2,500 ngā kārani wai puna penapena e whāngai ana i te whare me te māra. He maha nga tau i tiakina ai e te hangarau ōrite i whakawhirinaki ai te tangata mai i ngā tau 1970: he whakakā mānu tekau mā rua tāra e tārewa ana i runga i te waea.
I tērā kōanga i mau. Kāore i mau — mau ki runga, he kino kē atu. Kī tonu te kura, I mahia e te paipa waipuke tana mahi, kātahi ka waipuke te mahi a te paipa waipuke i te whārangi mō te ono haora tōtika i a au i tētahi whakaaturanga hokohoko kotahi haora te tawhiti. I hoki mai ahau ki te kāinga ki te repo, he papa wharau wai, me tētahi pūmana papu i te wera tae noa ki te mutunga. I pau i a au taua papu whakakapi $380 me te mutunga wiki e kore au e hoki mai.
Anei hoki te wāhanga i tino whakapai ake ai ahau: E rua marama i muri mai ka pērā tonu te mahi a te mānu whakakapi, ki te whakamuri anake. I whakairi i runga i te algae, kāore i kī atu ki te papu kia mutu, a, ka maroke te papu, ka wera. Anō. I tērā wā ka oati ahau i ngā mānu mīhini mō te pai, ā, ka tīmata ahau ki te pānui mō ngā pūoko taumata ultrasonic pēnei i te tangata.
He aha i mahue ai i ahau aku whakakā mānu
Titiro, ehara i te kino ngā whakakā mānu. He ngāwari noa iho, he tino māmā, me te pono? Mō tētahi rua waipuke i te papa o raro, Kei te pai rātou. Engari mō tētahi kura e tino whakawhirinaki ana koe, e toru ō rātou raruraru i akona e au i te huarahi uaua:
Tuatahi, he mīhini, me ngā mea mīhini e tāmi ana. Tauine, almue, otaota, he waea e mau ana i te ringa — hoatu kia kotahi tau, ā, ka kitea he huarahi ki te teka ki a koe. Hēkona, He ā-rua te mānu: ka kī atu ki a koe "kī", "putu" rānei i te wā kotahi tonu, ā, kāore he mea i waenga. Kāore he ia, kāore he whakatūpato, kāore he "hey, kua tae koe ki 60% ā, kei te rerekē te mahi a tō mapu." Tuatoru, kāore e taea e koe te kite mai i tētahi wāhi. E ono haora taku taraiwa ki te kāinga mai i taua whakaaturanga hokohoko me te kore mōhio mēnā kei te waipuke taku whārangi. Ehara tēnā i te aroturuki - ko te tūmanako.
He aha tonu te mahi a te mea (Kāore he tohu pūkaha e hiahiatia ana)
He ngāwari noa iho te ariā o te pūoko ultrasonic i tāutatia e au. I roto i te whare he transducer piezoelectric — he kaikōrero iti ka taea hoki te whakarongo. Ka pūhia e ia tētahi mokowhiti oro auau tiketike ki raro i te mata o te wai, ka hoki anō te manawa, ā, ko te pūtukatuka moroiti e whakawā ana i te haerenga huri noa pēnei i tētahi matawā tino pū. I te mea he nui e mōhiotia ana te tere o te oro i roto i te hau, Ko te tawhiti ki te wai — nō reira ko te taumata i roto i te kura — he tauhanga noa iho.
Ko te wāhanga mātauranga he aha te mea ka tūpono ina ehara ngā here i te pukapuka. He tere ake te haere o te oro i te hau mahana, he pōturi ake i te hau mātao, ā, ko te hau i runga ake i te kura e kore rawa e pāmahana pūmau. Nā reira ka mau ēnei wae i tētahi thermistor rō-tonu me te utu aunoa. Kaore te ngaru wera i a Hōngongoi, i te pō mātao rānei i Hānuere e maka atu i te pānui. I tirohia e au taku ki tētahi rīpene ine i ētahi wā i te wiki tuatahi — i roto i te hauwhā inihi i ia wā.
E rua ngā mea e hiahia ana ahau kia mōhio ahau i mua i te hoko:
Te pēne mate. He kāpō ia pūoko ultrasonic mō ngā inihi tuatahi i raro tonu i tōna kanohi - kāore e taea te ahi me te whakarongo i te wā kotahi. Mēnā ka kī te kura ki taua rohe, Ka hē noa iho rānei ngā pānuitanga. Whakamautia kia teitei rawa kia noho wātea ai te taumata whakakī mōrahi i tēnei.
Kāore he mea e pā ana ki te wai. Koia tēnā te take katoa. Koia te take i whakamahia ai taua hangarau i runga i ngā kura matū - ka penapena tētahi hoa o taku hoa i te rongoā konutai hypochlorite, ā, e kore rawa ia e puru i tētahi mānu, i tētahi rūpahu rānei ki tētahi wāhi tata ki taua mea. Kāore he hoapā, ko te tikanga kāore he waikura, kāore he poke, Kāore he wāhanga nekeneke hei rahua. Ko te tautiakitanga ko te "ūkui kotahi i te tau."
Mānu vs. ultrasonic vs. hihiani — te putanga pono
Ko ia kaipūkaha i kōrero ahau ka mau tonu mai i te hihiani, nō reira me whakatau tātou. Ka whakamahi te hihiani i ngā ngaruiti, kaua ko te oro, nā reira ka āraia e ia ngā mea e whakararuraru ana i te ultrasonic: kohu taumaha, puehu, huka, ngā huringa pāmahana mohoao. Ko taku hoa e whakahaere ana i tētahi tipu wai pūwhenua e whakamahi ana i te hihiani i runga i ngā kura kūnatu, kei reira tētahi apa pūmau o te huka — kāore e taea e te ultrasonic te kite i tēnā.
Engari he moni tūturu te utu hihiani, ā, he pai ake te tatū. Kei te kōrero mātou i te $2,000-plus mō ia koromeke mō tētahi wae tika, ā, me hiahia koe ki tētahi tangata e mōhio ana ki ā rātou mahi hei whirihora. Mō te wai, hinu, matū ngawari, ngā puna wai, ngā kura wai marangai — te mea hōhā, engari he mea hira 90% o te ao — ka hoatu e te ultrasonic ki a koe te motukore ōrite, raraunga taumata tika i te hautanga o te utu. Ko te huka tōna wāhi ngoikore; mēnā ka huka tō kura, Tīpoka hāngai tonu ki te hihiani, whakaurua rānei he poka whakangāwari. Ki te kore, kaua e whakaaro nui rawa.
He aha te utu, me ngā mea ka hokona anō e au
Ka neke haere ngā utu, nā reira whakamahia ēnei hei tau tiriti o Amerika i te wā e hokohoko ana ahau:
Ko te whakakā mānu i tīmata ai ahau: $12–25 i Amazon. Ka whiwhi koe i tāu e utu ai.
Ara DIY: he kōwae ultrasonic JSN-SR04T waikore e rere ana $12 mēnā he pai ki a koe te raweke Arduino. He pai ki a au i roto i te ariā. I roto i te mahi i hiahia ahau ki tētahi mea e mahi ana me te kore rino soldering i 11 p.m.
Te wāhi i ū ai ahau: he kaituku ultrasonic 4-20mA whakatauranga IP68 whānui, roughly $220 i Amazon — koki kurupae ka taea te whakarite, pēhi pāoro teka rō-tonu, nga mahi. I takiruatia ki tētahi waharoa pūkoro ~$130 e whāngai ana i tētahi taupānga i taku waea. Kāore he Wi-Fi i te wharau, Nā reira ko te pūkoro anake te kōwhiringa pono.
Te taumata ahumahi ingoa: Mēnā e hiahia ana koe ki ngā tiwhikete me tētahi raina tautoko, te Siemens Sitrans LU150, te Endress Hauser Prosonic FMU30, he VEGA VEGASON rānei 61 oma ki hea mai i $700 ki $1,000+, A, i mua i tō hoko i tētahi taura kotahi.
Te kōwhiringa māngere-engari-atamai: ngā kaupane kura LoRa hiko-pūhiko (ngā mea kāhua-YoLink) haere mō te $50–70 me te $30 pokapū. Kāore he waea, ā, he pai te taupānga. Ka ngaro i a koe te huaputa 4-20mA e hiahiatia ana e tētahi PLC, pūmana rānei, engari mēnā ko tō whāinga ko te "tirohia te kura mai i taku waea," He pono te uara tino pai i runga i te rārangi.
Ko aku tohutohu: kaua e hoko i te $12 kāore i te mōhiotia, kaua hoki e hoko i te $1,000 waitohu ingoa ki te kore koe e tino hiahia. Pānuitia te rauraraunga mō ngā tau e toru — te tāhei mate, koki kurupae, me te whakatauranga IP — ā, ka pai koe.
Tāutanga: i te wāhi i takakino ai ahau kia kore ai koe e hiahia
Ka hāngai tonu ahau ki a koe: I hē taku tāuta tuatahi. He iti rawa taku whakatū i te pūoko, i te taumata i whakaaro ahau ko te whakakī mōrahi - arā, i te wā i tino kī ai te kura, Ka tomo te wai ki te tāhei tūpāpaku, ā, ka tīmata te taupānga ki te whakaatu para. I pau i a au te ahiahi katoa e mōhio ana kua hokona e au tētahi wae hē i mua i taku pānui anō i te pukapuka, i pēnei i te pōrangi, ka nekehia ki runga e ono inihi.
Ina tika te whakatū, he mahi e rua haora: wiri poka, whakauru i tētahi repe taura, Whakamautia te pūoko kia teitei rawa hei ūkui i te tāhei mate, ka whakahaere i te koromeke 4-20mA waea rua ki te pūmana. Ka whakahuatia ahau e tētahi kaihiko $350 mō taua rere taura; I mahia e au anō me tētahi hoa, he wiri, me YouTube, ā, he pai. He mahi tahua noa iho te tōkarikari: tautuhi i te ira kore (tawhiti ki te takere o te kura kore), tautuhi i te roanga (tawhiti ki te whakakī mōrahi), kātahi ka whakahaere i te mahi "whakaako" e whakamahere ana i ngā pāoro pūmau o te kura — he arawhata, paipa, te pakitara e tāwhana ai te kurupae — kia ako ai te pūoko ki te waiho i a rātou. Tekau meneti te roa.
One honest caveat: i muri i te ua nui ka whiwhi ahau i te pānui tiketike hē mō te haora kotahi i te wā ka huka te mata. I mārama te whakaatu a te hītori taupānga, kāore he mea i whakaweto, ā, kāore anō kia tāruatia. Pōrearea, ehara i te mea mōrearea — engari ināianei kua mōhio koe.
Te whakahekenga ohorere mai i taku māngai inihua
Kāore au i tata whakaurua tēnei nā te mea he tinihanga, engari he tūturu. I muri i te waipuke o te papa o tētahi hoa noho (ngongo mīhini horoi, $14,000 pakaru), I pātai atu ahau ki taku māngai mehemea he mea nui ētahi o aku taonga mō taku kaupapa here. Ka puta he maha ngā kaikawe e tuku ana i te whakahekenga 3–5% i runga i te kapinga o ngā kaipupuri kāinga mēnā ka taea e koe
