Ōmata (Pōkākā) Hoahoa Waea Pūoko Taumata Wai

Te hoahoa waea pūoko taumata ōmata mō tētahi pūoko taumata wai 3-waea 3-waea / IR he ngāwari: Hono VCC ki tētahi putanga 5V, GND ki te whenua ngātahi, me OUT ki te tāurunga mamati, tāurunga kōwae tānga, kāpeka tohu whakakā-mana rānei. Mō tētahi Huaputa kaikohi-tuwhera NPN, kāore te waea OUT e whakaputa ngaohiko i ngā wā katoa; i te nuinga o te wā e hiahiatia ana he kume-ake kia taea ai e te pūmana te pānui i tētahi tohu HIGH/LOW mārama.

I roto i ngā tikanga ā-ringa: whakahikotia te pūoko, tiritiri whenua, kumea whakarunga te tohu, kātahi ka tukua te waea OUT ki te whakawhiti i te tāurunga pūmana, i te atanga tānga rānei. Kaua e tīmata mā te matapae i ngā tae waea—whakaūngia te pinout mai i te rauraraunga, i ngā tuhinga kaiwhakarato rānei i mua i te hoatu hiko.

Hoahoa Waea Tere ki ngā Kupu

Mō tētahi pūoko taumata wai ōmata 3-waea noa:

VCC → 5V DC
Tūhonoa te waea putanga tōrunga o te pūoko ki te huaputa 5V o te pūmana, ki tētahi puna hiko 5V rānei kua whakaritea.

GND → 0V / Whenua
Tūhonoa te whenua pūoko ki te whenua puna hiko me te whenua pūmana. Arduino, Ngā papa atanga Raspberry Pi, Ngā tāurunga PLC, kōwae tānga, ā, me tiritiri te hiko pūoko i tētahi whenua tohutoro.

OUT → Tāuru mamati, tāurunga mana tānga rānei
Tūhono OUT ki te pine tāuru e hiahia ana ki te kite i te aroaro wai. Mēnā ko te pūoko Kaikohi tuwhera NPN, Ka mahi te OUT pēnei i te whakakā totohu. Ka kumea whakararo te tohu ina hohe, nā reira me kume ake te tāuru ki te 5V.

Kume-ake → OUT ki VCC
Mā te kume-ake ka taea te pānui i te tohu ina kāore te transistor NPN i te tō pāpaku. Ka taea e ētahi pūmana moroiti te whakamahi i tētahi kume-ake ā-roto; Ka hiahiatia pea e ngā pūmana ahumahi, ngā kōwae tānga rānei te taura tāuru tika e ai ki tō rātou hoahoa ara iahiko.

Te whakakā tāpae, te whakakā mana rānei → te whakamahi i tētahi atanga
Mēnā kei te whakawhiti papu koe, kōrere, whakaoho, tānga rānei, Whakamahia he kōwae tāpae, he ara iahiko transistor/atekōkiri rānei. Kaua e whakaaro ka taea e te waea pūoko OUT te whakahiko hāngai i tētahi tāpae tānga.

3-Waea Ōmata / Ripanga Pinout Pūoko Taumata Wai IR

He tauira noa iho ngā tae waea. Whakaūngia te pinout tūturu i mua i te waea i ngā wā katoa, otirā mō ngā pūoko OEM/ODM, Ngā putanga whakamau-paewhiri, me ngā huihuinga taura ritenga ake.

Pine Pūoko / waea	Taumahi Pūnoa	Tūhono Ki	Ngā Tuhipoka Waea
VCC / +5	Tāurunga hiko pūoko	5Putanga V DC i roto i tētahi tatūnga whakamātautau pūnoa	Whakamahia te ngaohiko i whakapūtātia mō tō tauira pūoko. Mō tēnei kaiārahi, ka whakamahi te tauira waea taketake i te 5V.
GND / 05	Whakahoki hiko	Tōraro te whenua pūmana me te puna hiko	Me tiritiri te whenua i waenga i te pūoko me te pūrere e pānui ana i te tohu.
PUTA / tohu	Whakawhiti ana i te huaputa	Tāurunga mamati, tāurunga kōwae tānga, tāurunga whakakā mana, Atanga tāuru PLC	Mō te huaputa kaikohi-tuwhera NPN, whakamahia he kume-ake kia taea ai e te tāuru te pānui i te TEITEI ina kāore te huaputa i te totohu.
Tūhononga kume-ake	Tohutoro tohu	ATU ki VCC	E hiahiatia ana ina kāore anō te tāuru kia homai he kume-ake.
Atanga tāpae/mana	Mana utanga	Kōwae tānga, atekōkiri whakawhitiwhiti, tāurunga pūmana rānei	Whakamahia tētahi wāhanga atanga mō ngā mapu, kōrere, whakaoho, ngā kawenga iahiko teitei ake rānei.

He pēhea te mahi o te huaputa kaikohi-tuwhera NPN

He maha ngā pūoko taumata wai whatu/IR 3-waea e whakamahi ana i tētahi Kaikohi tuwhera NPN huaputa. Ko te tikanga o tēnei ka rite te whanonga o te huaputa pūoko ki te whakawhiti ki te whenua, ehara i te rite ki te huaputa ngaohiko hiko.

Ki te tautauā te huaputa pūoko, ka mānu pea te waea OUT ki te kore he kume-ake. Mā te kume-ake, ka pānui te tāuru i te HIGH. Ina hohe te huaputa pūoko, ka kumea ATU te transistor ā-roto ki te whenua, kia pānui ai te tāuru i te ITI.

Koinei te take i whakaaro ai te tokomaha o ngā kaiwhakamahi i te "kore e hoatu ngaohiko." Ko te mea pono, Kei te mahi tika pea te huaputa, Engari kei te ngaro te ara iahiko i tētahi kume-ake, kāore rānei te tāurunga pūmana i whirihora tika.

Mō tētahi pūmana moroiti, I te nuinga o te wā, ka hono atu te OUT ki tētahi tāuru mamati. Mō tētahi pūmana mahi, Ka hono pea te OUT ki tētahi hongere tāuru mamati hototahi. Mō tētahi kōwae tānga, Me tūhono anake te OUT ki te tāurunga tohu ina hototahi te momo tāuru kōwae ki tētahi tohu NPN e totohu ana.

Arorau Mākū vs Maroke: NO me te Whanonga NC

Ka kitea e ngā pūoko taumata wai ōmata mēnā kei te hau, kei te hipoki rānei te aki i te wai. Kei roto i te pūoko, ka tukua e tētahi LED IR te mārama ki roto i te pito pororua, ā, ka kitea e te whakaahua te rama i whakahokia mai. Kia maroke te pito, He rerekē te whakaata o te mārama i roto i te pororua. Ina taupoki te wai i te pito, ka huri te āhua tāhapa, nā reira ka kite te kaiwhiwhi i tētahi tohu rerekē.

Kei te āhua tonu te arorau huaputa i te hoahoa pūoko:

• KORE arorau ka whakakā anake ina tae te wai ki te pito pūoko.
• Arorau NC ka whakaweto pea ina tae te wai ki te pito pūoko.
• E wātea ana ētahi hua i roto i ngā putanga huaputa rerekē.
• Ka huripoki ētahi pūnaha mana i te arorau i roto i te pūmanawa, kaua e huri i ngā pūmārō.

Nā te mea ka rerekē te whanonga mākū/maroke i te tauira, kaua e whakawhirinaki anake ki te tapanga "pūoko taumata wai ōmata." Whakaūngia mēnā kei te hiahiatia tō āhua haumaru mākū = hohe, maroke = hohe, mākū = PĀPAKU, rānei maroke = ITI.

Mō te parenga oma maroke papu, He maha ngā kaipūkaha e hiahia ana ki tētahi whakaritenga arorau e taea ai te whakamahi i tētahi waea whati, i te tohu ngaro rānei hei hē. Mō ngā pūoho waipuke, Ko te manakē he tere te kitenga ina tae te wai ki te taumata tiketike.

Tūhono ana ki tētahi tāpae, ki tētahi whakakā mana rānei

Mēnā ka whakamahia te pūoko ōmata hei whakakā mana, ko te tikanga kia taraiwa te tohu OUT i tētahi tāurunga mana, ehara i te utanga hāngai.

Ko tētahi ariā waea haumaru ko te:

Pūoko VCC → 5V
Pūoko GND → whenua ngātahi
Pūoko OUT → tāuru kōwae tānga tāuru, tāurunga pūmana rānei
Tānga hoapā → papu, kōrere, puoro, whakaoho, ara iahiko mana rānei

Ka mahia e ngā hoapā tānga te whakawhiti utanga. Ka homai anake e te pūoko te tohu taumata.

Mō te tāpae tānga tahanga, Whakamahia he wāhanga atekōkiri tika. Kāore te huaputa pūoko i te whakakapi i tētahi atekōkiri tānga ki te kore e whakaūngia te whakatauranga me te hoahoa ara iahiko o nāianei. Me parenga hoki ngā kawenga aukuhu pēnei i te pēhitanga puta noa i te hurihuri, i te ara iahiko utanga rānei. I roto i ngā taputapu OEM, i te nuinga o te wā ka whakahaeretia tēnei i runga i te PCB mana, i te kōwae tānga rānei.

Mēnā kei te hanga koe i tētahi tauira tauira ngāwari, He ngāwari kē atu te kōwae tānga me te tāuru tohu i te tāpae tānga tārewa. Mēnā kei te hoahoa koe i tētahi hua, Whakaūngia te momo tāuru, whakaoho i te pāhekoheko, utaina te iahiko, hiahia taratahi, me te whanonga hē i mua i te whakaotinga o te waea.

Whakamātau ana i te pūoko i mua i te tāutanga

Whakamātauria te waea i runga i te tēpu i mua i te tāuta i te pūoko ki roto i te kura.

Tuatahi, tūhonoa te VCC me te GND ki te putanga 5V tika me te manatoko i te polarity. Kātahi ka tūhono ki te OUT ki tētahi tāuru mamati, pūwāhi whakamātau mita rānei me te kume-ake tika. Kia maroke tonu te aki pūoko me te mātakitaki i te āhua huaputa. Muri atu, taupokina te pito poroporo ki te wai, ka mātakitaki mēnā ka rerekē te OUT.

Mēnā ka huri te tohu ina mākū te pito, Kei te whakawhiti te pūoko. Ki te kore te tohu e huri, tirohia te hiko, whenua, kume-ake, me te aratau arorau i mua i te whakapae i te pūoko.

Ka taea e te inemaha te āwhina, Engari kia mahara kāore pea te huaputa kaikohi tuwhera e whakaatu i tētahi ngaohiko mā ki te kore e tika te kume-ake me te whenua noa. Mō te whakamātau pūmana moroiti, Tāngia te āhua tāuru ki te pūmanawa. Mō te whakamātau tānga, Mātakina te tohu kōwae tānga me te whakarongo ki te hohenga tānga i muri noa iho i te whakaūnga kua tika te aho o te kōwae.

Arorau mākū/maroke whakamuri
Ka mahi te pūoko, engari he tauaro te pūmanawa, te hohenga tānga rānei. Whakaūngia te arorau NO/NC ka huripoki i te tāuru i roto i te pūmanawa, tīpako rānei i te putanga huaputa tika.

Ngana ana ki te taraiwa hāngai i tētahi tāpae tānga
Ka rahua pea te huaputa, kāore rānei te tānga e whakawhiti. Whakamahia he kōwae tānga, atekōkiri whakawhitiwhiti, wāhanga tāuru pūmana rānei.

Aki pororua paruparu
Kiriata hinu, Tauine, toenga huka, ka taea rānei e te tāhaetanga whakapiri te ārai i te whakawhiti ōmata pono. Horoia te pororua me te taki i te hototahitanga matū.

Horahanga whakaata, whakamau kikī rānei
Ngā whakaata pakitara kura, mirumiru, ka kore rānei e taea e te whakatūpato te kite i te tūkino. Whakamautia te pūoko kia mā ai te whakapā atu o te pito poroporo ki te wai ūnga.

Rauemi pūoko hē
Wai, hinu, matū, wai kōeke kai, kora, ā, e hiahiatia ana e ngā wai waikura ngā rauemi mākū rerekē. Whakaūngia te hototahitanga i mua i te tono.

Ngā Rauemi, Whakatū ana, me ngā Kōwhiringa Huaputa Me Taki e ngā Kaihoko

Ka whakaoti te hoahoa waea i te hononga hiko, engari ko te tīpakonga pūoko tika kei te āhua tonu o te wai, hoahoa kura, me te pūmana.

Mō te haurapa taumata-ira whatu/whakaahua, I te nuinga o te wā ka hangaia te aki pūataata mai i tētahi rauemi poroporo pūataata. E ai ki te taupānga, ka hiahiatia pea e ngā kaihoko te PSU, PTFE, 316 whare tīra poapoa, ngā hoahoa hoa-karaehe rānei. Ka taea e ngā kura wai me ngā pūrere te whakamahi i ngā pūoko tinana kirihou kiato. Ka hiahiatia pea e ngā kura matū te PTFE, te hanganga poapoa rānei. Me āta arotake ngā taupānga hinu me te hinu nā te mea e pupuhi ana, poapoa, ka pā rānei te toenga ki te whaikikotanga mo te wā roa.

He mea nui hoki te whakatū. Kua tāutatia ētahi pūoko mā tētahi tauranga miro, ā, ko ētahi e whakamahi ana i te whakatūnga paewhiri, Ngāwari ritenga ake, hanga rape kiato, huihuinga whakamau-taura rānei. Me noho te pito pororua ki te teitei whakawhiti tūturu, kaua i runga ake i te rohe mate, i roto rānei i tētahi pūkoro kāore e tae mā te wai.

Ko te momo huaputa tētahi atu whakataunga hoko. He mea noa iho te NPN mō te totohu i ngā tāurunga mamati. Ka manakohia pea te PNP e ētahi pūnaha whakahaere ahumahi. Mō te inenga taumata motukore, ka taea e ngā kaihoko te whakaaro i te huaputa tairitenga pēnei i te 4–20 mA, kaua ko te whakawhiti ira māmā. E arotahi ana tēnei tuhinga ki te taura taumata-3 waea nā te mea koia te hiahia tino noa i muri i te rapunga hoahoa waea.
