Ngaqala ukuhlola Umsizi Wasekhaya futhi ukuze ngikwazi ukuqala ukudala okuthile okuzenzakalelayo, kwakudingeka ngibe namanani wamanje wezinga lokushisa nomswakama osuka egumbini lami lokuphumula ngaphakathi ukuze ngikwazi ukuwenza.
Kukhona izixazululo zezentengiso ezitholakalayo zalokhu kodwa bengifuna ukuzakhela eyami ukuze ngifunde kangcono ukuthi Umsizi Wasekhaya usebenza kanjani nokuthi ungawamisa kanjani amadivayisi angokwezifiso ngawo kanye ne-ESHome.
Yonke iphrojekthi yakhelwe ku-PCB eyenziwe ngokwezifiso engiyiklame njengenkundla yephrojekthi ye-NodeMCU futhi yabe yenziwa ngabangane bami kwa-PCBWay. Ungazi-oda leli bhodi ngokwakho futhi ube nezingcezu eziyi-10 ezenzelwe u-$5 nje: https://www.pcbway.com/project/shareproject/NodeMCU_Project_Platform_ce3fb24a.html

Isinyathelo 1: I-PCB Yangokwezifiso
Ngiklame le PCB ukuthi isebenze njengenkundla yephrojekthi ngemuva kokuchitha isikhathi esiningi ngithengisa amaphrojekthi we-NodeMCU ngokwezifiso kuma-PCB we-prototyping.
I-PCB inesikhundla se-NodeMCU, amadivayisi we-I2C, amadivayisi we-SPI, ama-relay, inzwa ye-DHT22 kanye ne-UART kanye nogesi we-HLK-PM01 onganika amandla iphrojekthi kusuka kumapayipi amakhulu e-AC.
Ungabheka ividiyo yokuklama noku-oda esiteshini sami se-YT.
Isinyathelo sesi-2: Solder the Components
Njengoba ngingafuni ukuthengisa i-NodeMCU ngqo ku-PCB, ngisebenzise izihloko zephinikhodi zabesifazane futhi ngazithengisa kuqala ukuze ngikwazi ukuxhuma i-Node MCU kuzo.
Ngemva kwezihloko, ngithengise amatheminali ayisikulufu okokufaka kwe-AC kanye nokuphumayo okungu-5V no-3.3V.
Ngiphinde ngathengisa unhlokweni wenzwa ye-DHT22 kanye ne-HLK-PM01 power supply.
Isinyathelo sesi-3: Hlola iVoltages kanye nenzwa
Njengoba kungokokuqala ngqa ukuthi ngisebenzise le PCB ngephrojekthi, bengifuna ukwenza isiqiniseko sokuthi angingcolisanga okuthile ngaphambi kokuxhuma i-Node MCU. Bengifuna ukuhlola ibhodi voltagukuthi konke kuhamba kahle. Ngemuva kokuhlola okokuqala ujantshi we-5V ngaphandle kwe-Node MCU exhunyiwe, ngixhume i-Node MCU ukuze ngiqiniseke ukuthi ithola i-5V nokuthi ibihlinzeka nge-3.3V kusuka kusilawuli sayo se-onboard. Njengesivivinyo sokugcina, ngilayishe njengeample sketch yenzwa ye-DHT22 evela kulabhulali ye-DHT Stable ukuze ngiqinisekise ukuthi i-DHT22 isebenza kahle nokuthi ngingakwazi ukufunda ngempumelelo izinga lokushisa nomswakama.
Isinyathelo sesi-4: Engeza Idivayisi Kumsizi Wasekhaya
Njengoba konke kusebenze njengoba bekulindelekile, ngabe sengiqhubeka nokufaka i-ESPPome ekusetheni kwami Komsizi Wasekhaya futhi ngiyisebenzisele ukwakha idivayisi entsha futhi ngilayishe i-firmware enikeziwe ku-NodeMCU. Ngibe nenkinga yokusebenzisa i- web layisha kusuka ku-ESPPome ukuze umlotha i-firmware enikeziwe kodwa ekugcineni, ngilande i-ESPHome Flasher futhi ngakwazi ukulayisha i-firmware ngisebenzisa lokho.
Lapho i-firmware yokuqala seyengezwe kudivayisi, ngilungise i-.yamlle ukuze yengeze isigaba sokuphatha se-DHT22 futhi ngilayishe kabusha i-firmware, manje ngisebenzisa isibuyekezo esisemoyeni esivela ku-ESPHome.
Lokhu kuhambe ngaphandle kokuphazamiseka futhi ngokushesha nje lapho sekwenziwe, idivayisi yabonisa amanani okushisa nomswakama kudeshibhodi.
Isinyathelo sesi-5: Yenza Indawo Ebiyelwe Unomphela
Bengifuna ukuthi le monitha igxunyekwe eduze kwe-thermostat yami yamanje enginayo endlini yami yesitofu se-pellet ngakho ngisebenzise ibhokisi lokuhlangana likagesi ukwenza indawo ebiyelwe. Inzwa ye-DHT22 ifakwe embobeni eyenziwe ebhokisini likagesi ukuze ikwazi ukuqapha izimo ezingaphandle kwebhokisi futhi ingaphazanyiswa yinoma yikuphi ukushisa okuphuma kumandla kagesi.
Ukuze uvimbele noma yikuphi ukwakheka kokushisa ebhokisini, ngiphinde ngenza izimbobo ezimbili phansi nangaphezulu kwebhokisi likagesi ukuze umoya ukwazi ukujikeleza kulo futhi ukhulule noma yikuphi ukushisa.
Isinyathelo sesi-6: Faka egumbini lami lokuhlala
Ukuze ngifake ibhokisi likagesi, ngangisebenzisa itheyiphu enezinhlangothi ezimbili ukuze nginamathisele ibhokisi odongeni nakwi-thermostat eseduze kwalo.
Okwamanje, lokhu kuwukuhlola kuphela futhi nginganquma ukuthi ngifuna ukushintsha le ndawo ukuze ngingafuni ukwenza izimbobo ezintsha odongeni.
Isinyathelo 7: Izinyathelo Ezilandelayo
Uma konke kuhamba kahle, ngingase ngithuthukise le phrojekthi ukuze isebenze njenge-thermostat yesitofu sami se-pellet ukuze ngilahle ngokuphelele esokuhweba. Konke kuncike ekutheni umsizi Wasekhaya uzongisebenzela kanjani ngokuhamba kwesikhathi kodwa kuzodingeka silinde ukuze sikubone lokho.
Okwamanje, uma uwuthandile le phrojekthi, qiniseka ukuthi uhlola neminye yami kokuthi Imiyalelo kanye nesiteshi sami se-YouTube. Nginabanye abaningi abangena ngakho ngicela ucabange nokubhalisa.
