Ndidayamba kuyang'ana Wothandizira Wanyumba ndipo kuti ndiyambe kupanga zodzipangira zokha, ndimayenera kukhala ndi kutentha komanso chinyezi chapano kuchokera pabalaza langa mkati kuti ndizitha kuchitapo kanthu.
Pali njira zamalonda zomwe zilipo pa izi koma ndinkafuna kupanga zanga kuti ndithe kuphunzira bwino momwe Wothandizira Pakhomo amagwirira ntchito komanso momwe angakhazikitsire zipangizo zamakono ndi ESPHome.
Ntchito yonseyi idamangidwa pa PCB yopangidwa mwachizolowezi yomwe ndidapanga ngati nsanja ya NodeMCU ndipo idapangidwa ndi anzanga ku PCBWay. Mutha kuyitanitsa nokha bolodi ndikukhala ndi zidutswa 10 zopangira $5 yokha pa: https://www.pcbway.com/project/shareproject/NodeMCU_Project_Platform_ce3fb24a.html

Gawo 1: The Mwamakonda PCB
Ndinapanga PCB iyi kuti ikhale ngati nsanja ya polojekiti nditatha nthawi yochuluka ndikugulitsa mapulojekiti a NodeMCU pama PCB a prototyping.
PCB ili ndi malo a NodeMCU, zida za I2C, zida za SPI, zotumizirana mauthenga, sensa ya DHT22 komanso UART ndi magetsi a HLK-PM01 omwe amatha kuyendetsa polojekitiyo kuchokera ku mains a AC.
Mutha kuwona kanema wamapangidwe ndi kuyitanitsa pa njira yanga ya YT.
Khwerero 2: Solder the Components
Popeza sindikufuna kugulitsa NodeMCU mwachindunji ku PCB, ndimagwiritsa ntchito mitu ya pini yachikazi ndikugulitsa kaye kuti nditha kulumikiza Node MCU mkati mwake.
Pambuyo pamitu, ndidagulitsa zomangira zolowetsa za AC komanso zotulutsa za 5V ndi 3.3V.
Ndinagulitsanso mutu wa sensa ya DHT22 ndi magetsi a HLK-PM01.
Gawo 3: Yesani Voltages ndi Sensor
Popeza aka kanali koyamba kuti ndigwiritse ntchito PCB iyi pantchito, ndimafuna kuonetsetsa kuti sindinasokoneze china chake ndisanalumikizane ndi Node MCU. Ndinkafuna kuyesa bolodi voltagndiye kuti zonse zili bwino. Nditayesa njanji ya 5V popanda Node MCU yolumikizidwa, ndidalumikiza Node MCU kuti ndiwonetsetse kuti ikupeza 5V komanso kuti ikupereka 3.3V kuchokera kwa wowongolera wake. Monga mayeso omaliza, ndidakweza ngatiample sketch ya sensa ya DHT22 kuchokera ku laibulale ya DHT Stable kotero nditha kutsimikizira kuti DHT22 imagwira ntchito bwino komanso kuti nditha kuwerenga bwino kutentha ndi chinyezi.
Khwerero 4: Onjezani Chipangizo kwa Wothandizira Pakhomo
Popeza zonse zidayenda momwe ndimayembekezera, ndidayamba kukhazikitsa ESPHome pakukhazikitsa kwa Wothandizira Wanga Wanyumba ndipo ndagwiritsa ntchito kupanga chipangizo chatsopano ndikuyika firmware yoperekedwa ku NodeMCU. Ndinali ndi vuto kugwiritsa ntchito web tumizani kuchokera ku ESPHome kuti muwononge firmware yoperekedwa koma pamapeto pake, ndinatsitsa ESPHome Flasher ndipo ndinatha kuyika firmware pogwiritsa ntchito izo.
Firmware yoyamba itawonjezeredwa ku chipangizocho, ndinasintha .yamlle kuti iwonjezere gawo la kusamalira DHT22 ndikubwezeretsanso firmware, tsopano ndikugwiritsa ntchito kusintha kwa mpweya kuchokera ku ESPHome.
Izi zidapita popanda zovuta ndipo zitangochitika, chipangizocho chidawonetsa kutentha ndi chinyezi padashboard.
Khwerero 5: Pangani Mpanda Wamuyaya
Ndinkafuna kuti polojekitiyi ikhale pafupi ndi chotenthetsera changa chomwe ndili nacho kunyumba kwanga chopangira chitofu cha pellet kotero ndidagwiritsa ntchito bokosi lamagetsi kuti ndipange mpanda. Sensa ya DHT22 imayikidwa mu dzenje lopangidwa mu bokosi lamagetsi kuti lizitha kuyang'anira momwe zinthu zilili kunja kwa bokosilo ndipo zisakhudzidwe ndi kutentha kulikonse komwe kumachokera ku magetsi.
Pofuna kupewa kutentha kulikonse m'bokosilo, ndinapanganso mabowo awiri pansi ndi pamwamba pa bokosi lamagetsi kuti mpweya uzitha kuzungulira ndikutulutsa kutentha kulikonse.
Khwerero 6: Phimbani M'chipinda Changa Chochezera
Kuyika bokosi lamagetsi, ndinagwiritsa ntchito tepi ya mbali ziwiri kumamatira bokosilo ku khoma ndi ku thermostat pafupi nayo.
Pakadali pano, uku ndi kuyesa kokha ndipo nditha kusankha kuti ndisinthe malowa kotero sindinkafuna kupanga mabowo atsopano kukhoma.
Gawo 7: Njira Zotsatira
Ngati zonse zikuyenda bwino, nditha kukweza pulojekitiyi kuti ikhale ngati chotenthetsera chitofu changa cha pellet kuti ndithe kusiya malonda. Zonse zimatengera momwe Wothandizira Kunyumba angandithandizire pakapita nthawi koma tiyenera kudikirira kuti tiwone.
Pakadali pano, ngati mudakonda pulojekitiyi, onetsetsani kuti mwayang'ananso zina zanga pa Instructables komanso njira yanga ya YouTube. Ndili ndi ena ambiri akubwera kotero chonde ganiziraninso zolembetsa.
