Ndiqale ukujonga uMncedisi waseKhaya kwaye ukuze ndikwazi ukuqalisa ukwenza i-automation, bendidinga ubushushu obukhoyo kunye namaxabiso okufuma ukusuka kwigumbi lam lokuhlala ngaphakathi ukuze ndikwazi ukwenza okuthile kubo.
Kukho izisombululo zorhwebo ezifumanekayo kule nto kodwa bendifuna ukuzakhela eyam ukuze ndifunde ngcono ukuba uMncedisi waseKhaya usebenza njani kunye nendlela yokuseta izixhobo zesiko kunye ne-ESHome.
Yonke iprojekthi yakhelwe kwi-PCB eyenziwe ngokwezifiso endiyilwe njengeqonga leprojekthi yeNodeMCU kwaye emva koko yenziwa ngabahlobo bam kwi-PCBWay. Ungaziodolela le bhodi kwaye ube namaqhekeza ali-10 enziwe nge-5 yeedola nje: https://www.pcbway.com/project/shareproject/NodeMCU_Project_Platform_ce3fb24a.html

Inyathelo 1: I-PCB eyenzelwe wena
Ndiyile le PCB ukuba isebenze njengeqonga leprojekthi emva kokuchitha ixesha elininzi ndithengisa iiprojekthi zeNodeMCU kwiprototyping PCBs.
I-PCB inesikhundla se-NodeMCU, izixhobo ze-I2C, izixhobo ze-SPI, ii-relays, i-sensor ye-DHT22 kunye ne-UART kunye nonikezelo lwamandla lwe-HLK-PM01 olunokuthi ke lunike amandla iprojekthi ukusuka kwi-AC mains.
Ungayijonga ividiyo yoyilo kunye nenkqubo yokuodola kwisitishi sam se-YT.
Inyathelo 2: Solder the Components
Kuba andifuni ukuthengisa i-NodeMCU ngqo kwi-PCB, ndisebenzise iiheader zephini zabasetyhini kwaye ndazithengisa kuqala ukuze ndikwazi ukuplaga iNode MCU kuzo.
Emva kweeheader, ndithengise iitheminali zesikrufu kwigalelo le-AC kunye ne-5V kunye ne-3.3V yeziphumo.
Ndiphinde ndathengisa i-header ye-DHT22 sensor kunye ne-HLK-PM01 yombane.
Inyathelo lesi-3: Vavanya iVoltages kunye noluvo
Kuba esi sisihlandlo sokuqala ndisebenzisa le PCB kwiprojekthi, bendifuna ukuqiniseka ukuba khange ndimoshe nto ngaphambi kokuba ndidibanise iNode MCU. Ndandifuna ukuvavanya ibhodi voltagukuba yonke into ilungile. Emva kokuvavanya okokuqala umzila we-5V ngaphandle kwe-Node MCU eplagiweyo, ndafaka i-Node MCU ukuqinisekisa ukuba ifumana i-5V kunye nokuba yayibonelela nge-3.3V kumlawuli wayo we-onboard. Njengovavanyo lokugqibela, ndalayisha njengeample sketch senzwa ye-DHT22 evela kwithala leencwadi le-DHT eZinzileyo ukuze ndiqinisekise ukuba iDHT22 isebenza kakuhle kwaye ndifunde ngempumelelo ubushushu kunye nokufuma.
Inyathelo 4: Yongeza isixhobo kuMncedisi wasekhaya
Kuba yonke into isebenze njengoko bekulindelekile, ndiye ndaqhubeka nokufaka i-ESPPome kwiseto yam yoMncedisi weKhaya kwaye ndiyisebenzisile ukwenza isixhobo esitsha kunye nokulayisha i-firmware enikiweyo kwiNodeMCU. Bendinengxaki yokusebenzisa i web layisha ukusuka kwi-ESPHome ukuya kwi-firmware enikeziweyo kodwa ekugqibeleni, ndakhuphela i-ESPHome Flasher kwaye ndakwazi ukulayisha i-firmware usebenzisa loo nto.
Emva kokuba i-firmware yokuqala yongezwa kwisixhobo, ndiyilungisile i-.yamlle ukuba yongeze icandelo lokuphatha i-DHT22 kwaye iphinde ilayishe i-firmware, ngoku isebenzisa uhlaziyo lwe-air-up ukusuka kwi-ESPHOme.
Oku kuhambe ngaphandle kokubetha kwaye ngokukhawuleza ukuba kwenziwe, isixhobo sabonisa amaxabiso obushushu kunye nokufuma kwideshibhodi.
Inyathelo lesi-5: Yenza indawo ebiyelweyo eSisigxina
Bendifuna le monitor ixhonywe ecaleni kwethermostat yam yangoku endinayo kwikhaya lam kwisitovu sepellet ndiye ndasebenzisa ibhokisi yokuhlangana yombane ukwenza indawo ebiyelweyo. I-sensor ye-DHT22 ifakwe emngxunyeni owenziwe kwibhokisi yombane ukuze ikwazi ukubeka iliso kwiimeko ezingaphandle kwebhokisi kwaye ingachaphazeleki naluphi na ubushushu obuphuma kumandla ombane.
Ukuthintela nakuphi na ukwakheka kobushushu ebhokisini, ndenze nemingxuma emibini ezantsi nangaphezulu kwebhokisi yombane ukuze umoya ujikeleze kuyo kwaye ukhulule nabuphi na ubushushu.
Inyathelo 6: Nyuka kwigumbi lam lokuhlala
Ukufakela ibhokisi yombane, ndandisebenzisa iteyiphu enamacala amabini ukuncamathisela ibhokisi edongeni nakwi-thermostat ecaleni kwayo.
Okwangoku, olu luvavanyo kuphela kwaye ndingathatha isigqibo sokuba ndifuna ukutshintsha le ndawo ukuze ndingafuni ukwenza nayiphi na imingxunya emitsha eludongeni.
Inyathelo 7: Amanyathelo Alandelayo
Ukuba yonke into ihamba kakuhle, ndingaphucula le projekthi ukuze isebenze njenge-thermostat yesitovu sam se-pellet ukuze ndilahle ngokupheleleyo esorhwebo. Konke kuxhomekeke kwindlela uMncedisi waseKhaya azakundisebenzela ngayo ekuhambeni kwexesha kodwa kuya kufuneka silinde ukuze sibone oko.
Okwangoku, ukuba uyayithanda le projekthi, qiniseka ukuba ujonga ezinye zam kwi-Instructions kunye nejelo lam likaYouTube. Ndinabanye abaninzi abezayo ngoko ndicela ucinge ngokubhalisa.
Ukubeka iliso kokusiNgqongileyo kuMncedisi weKhaya ngeNodeMCU kunye neDHT22:
