Ke ile ka qala ho hlahloba Mothusi oa Lehae 'me e le hore ke tsebe ho qala ho iketsetsa, ke ne ke hloka ho ba le litekanyetso tsa mocheso le mongobo tse teng hona joale ka phaposing ea ka ea ho phomola ka hare hore ke tsebe ho sebetsana le tsona.
Ho na le litharollo tsa khoebo tse fumanehang bakeng sa sena empa ke ne ke batla ho iketsetsa ea ka e le hore nka ithuta hamolemo hore na Mothusi oa Lehae o sebetsa joang le mokhoa oa ho theha lisebelisoa tsa tloaelo ka eona le ESPhome.
Morero oohle o hahiloe holim'a PCB e entsoeng ka tloaelo eo ke e entseng e le sethala sa morero bakeng sa NodeMCU 'me e ile ea etsoa ke metsoalle ea ka ho PCBWay. U ka iketsetsa boto ena 'me u be le likotoana tse 10 tse entsoeng ka $5 feela ho: https://www.pcbway.com/project/shareproject/NodeMCU_Project_Platform_ce3fb24a.html

Mohato oa 1: The Custom PCB
Ke thehile PCB ena hore e sebetse e le sethala sa morero ka mor'a ho qeta nako e ngata ke rekisa merero ea NodeMCU ho prototyping PCBs.
PCB e na le boemo ba NodeMCU, lisebelisoa tsa I2C, lisebelisoa tsa SPI, li-relays, sensor ea DHT22 hammoho le UART le motlakase oa HLK-PM01 o ka khonang ho matlafatsa morero ho tloha ho AC mains.
U ka sheba video ea moralo le ts'ebetso ea ho odara seteisheneng sa ka sa YT.
Mohato oa 2: Solder the Components
Kaha ha ke batle ho rekisa NodeMCU ka kotloloho ho PCB, ke sebelisitse lihlooho tsa phini tsa basali ebe ke li rekisa pele hore ke khone ho hokela Node MCU ho tsona.
Ka mor'a lihlooho, ke ile ka rekisa li-screw terminals bakeng sa tlhahiso ea AC hammoho le 5V le 3.3V e hlahisoang.
Ke boetse ke rekisitse hlooho bakeng sa sensor ea DHT22 le phepelo ea motlakase ea HLK-PM01.
Mohato oa 3: Lekola Moqtages le Sensor
Kaha ke lekhetlo la pele ke sebelisa PCB ena bakeng sa projeke, ke ne ke batla ho etsa bonnete ba hore ha ke so sothile ho hong pele ke hokela Node MCU. Ke ne ke batla ho lekola boto voltagke hore tsohle li lokile. Kamora ho qala ho hlahloba seporo sa 5V ntle le Node MCU e kenngoeng, ke ile ka hokela Node MCU ho etsa bonnete ba hore e fumana 5V le hore e fana ka 3.3V ho tsoa ho molaoli oa eona oa onboard. E le teko ea ho qetela, ke ile ka kenya e leample sketch bakeng sa sensor ea DHT22 ho tsoa laeboraring ea DHT Stable e le hore nka netefatsa hore DHT22 e sebetsa hantle le hore nka khona ho bala mocheso le mongobo ka katleho.
Mohato oa 4: Kenya Sesebelisoa ho Mothusi oa Lehae
Kaha ntho e 'ngoe le e' ngoe e ne e sebetsa kamoo ho neng ho lebelletsoe, ke ile ka tsoela pele ho kenya ESPHome ho setupong sa ka sa Mothusi oa Lehae mme ke e sebelisitse ho theha sesebelisoa se secha le ho kenya firmware e fanoeng ho NodeMCU. Ke bile le bothata ba ho sebelisa web kenya ho tloha ESPhome ho ea molora firmware e fanoeng empa qetellong, ke ile ka kopitsa ESPHome Flasher 'me ka khona ho kenya firmware ka eona.
Hang ha firmware ea pele e kenngoa ho sesebelisoa, ke ile ka fetola .yamlle bakeng sa hore e kenye karolo ea ho sebetsana le DHT22 le ho kenya firmware hape, hona joale e sebelisa tlhahiso-leseling e tsoang ho ESPHome.
Sena se ile sa tsoela pele ntle le bothata 'me hang ha se etsoa, sesebelisoa se ile sa bontša litekanyetso tsa mocheso le mongobo ka har'a dashboard.
Mohato oa 5: Etsa Sebaka se sa Feleng
Ke ne ke batla hore monitor ena e kenngoe pela thermostat ea ka ea hajoale eo ke nang le eona lapeng la ka bakeng sa setofo sa pellet kahoo ke sebelisitse lebokose la mateano la motlakase ho etsa sebaka se kampetsoeng. Sensor ea DHT22 e kenngoa ka sekoting se entsoeng ka lebokoseng la motlakase e le hore e ka shebella maemo a ka ntle ho lebokose mme e se ke ea angoa ke mocheso leha e le ofe o tsoang ho matla a matla.
Ho thibela mocheso o mong le o mong ka lebokoseng, ke ile ka boela ka etsa masoba a mabeli ka tlaase le ka holimo ho lebokose la motlakase e le hore moea o ka potoloha ka lona ebe o lokolla mocheso leha e le ofe.
Mohato oa 6: Mount ka Phaposing ea ka ea Bolulo
Ho kenya lebokose la motlakase, ke ne ke sebelisa teipi e mahlakoreng a mabeli ho khomaretsa lebokose leboteng le thermostat e haufi le lona.
Hajoale, sena ke teko feela 'me nka etsa qeto ea hore ke batla ho fetola sebaka sena kahoo ke ne ke sa batle ho etsa masoba a macha leboteng.
Mohato oa 7: Mehato e Latelang
Haeba tsohle li tsamaea hantle, nka ntlafatsa projeke ena hore e sebetse e le thermostat bakeng sa setofo sa ka sa pellet e le hore ke tlohele sa khoebo ka botlalo. Tsohle li ipapisitse le hore na Mothusi oa Lehae o tla nthusa joang kamora nako e telele empa re tla tlameha ho ema ho bona seo.
Khabareng, haeba u ratile morero ona, etsa bonnete ba hore u sheba le tse ling tsa ka ho Litaelo le mocha oa ka oa YouTube. Ke na le ba bang ba bangata ba tlang kahoo ka kopo nahana le ho ingolisa.
