Nzọụkwụ 1: The Custom PCB
Emebere m PCB a ka ọ bụrụ usoro ọrụ ngo mgbe etinyechara oge dị ukwuu n'ịzụ ọrụ NodeMCU omenala na PCBs prototyping.
PCB nwere ọnọdụ maka NodeMCU, ngwaọrụ I2C, ngwaọrụ SPI, relays, ihe mmetụta DHT22 yana UART na ọkụ ọkụ HLK-PM01 nke nwere ike mezie ọrụ ahụ site na isi AC.
Ị nwere ike ịlele vidiyo nke usoro nhazi na ịtụ na ọwa YT m.
Kwụpụ 2: Na-ere ihe akụrụngwa
Ebe ọ bụ na achọghị m ịre NodeMCU ozugbo na PCB, eji m nkụnye isi nwanyị na-ebu ụzọ were resị ha ka m nwee ike itinye Node MCU n'ime ha.
Mgbe ndị nkụnye eji isi mee ihe, e rere m ọdụ ụgbọ mmiri maka ntinye AC yana maka 5V na 3.3V.
E rerekwa m nkụnye eji isi mee maka ihe mmetụta DHT22 na ọkụ ọkụ HLK-PM01.
Nzọụkwụ 3: Nyochaa Voltages na Sensọ
Ebe ọ bụ na nke a bụ oge mbụ m na-eji PCB a maka ọrụ, achọrọ m ijide n'aka na emebeghị m ihe ọ bụla tupu ijikọ Node MCU. Achọrọ m ịnwale bọọdụ voltages na ihe niile dị mma. Mgbe anwalechara ụzọ ụgbọ okporo ígwè 5V na-enweghị Node MCU, etinyere m na Node MCU iji jide n'aka na ọ na-enweta 5V nakwa na ọ na-enye 3.3V site na onye na-ahụ maka ụgbọ mmiri ya. Dịka ule ikpeazụ, ebugoro m dị kaample sketch maka DHT22 sensọ si DHT Stable ọba akwụkwọ ka m nwee ike ịchọpụta na DHT22 na-arụ ọrụ nke ọma na m nwere ike nke ọma ịgụpụta okpomọkụ na iru mmiri.
Kwụpụ 4: Tinye ngwaọrụ na nnyemaaka ụlọ
Ebe ọ bụ na ihe niile na-arụ ọrụ dị ka a tụrụ anya ya, agara m wụnye ESPHome na ntọala onye enyemaka ụlọ ma ejiri m ya mepụta ngwaọrụ ọhụrụ wee bulite ngwa ngwa enyere na NodeMCU. Enwere m nsogbu iji web bulite site na ESPHome ka ash firmware nyere mana n'ikpeazụ, ebudatara m ESPhome Flasher na enwere m ike bulite ngwa ngwa site na iji nke ahụ.
Ozugbo agbakwunyere ngwa ngwa mbụ na ngwaọrụ ahụ, agbanwere m .yamlle ka ọ gbakwunye ngalaba njikwa DHT22 wee bulitekwa firmware ahụ, ugbu a na-eji mmelite ikuku sitere na ESPhome.
Nke a gara n'enweghị nsogbu na ozugbo emechara ya, ngwaọrụ ahụ gosipụtara ụkpụrụ okpomọkụ na iru mmiri na dashboard.
Nzọụkwụ 5: Mepụta ogige na-adịgide adịgide
Achọrọ m ka edowe ihe nlebanya a n'akụkụ temometa m ugbu a nke m nwere n'ụlọ m maka stovu pellet ka m jiri igbe mgbako eletrik mee ihe mkpuchi. A na-etinye ihe mmetụta DHT22 n'ime oghere emere n'ime igbe eletrik ka o wee nwee ike nyochaa ọnọdụ dị n'èzí igbe ahụ ma ghara inwe mmetụta nke okpomọkụ ọ bụla na-esi na ọkụ eletrik pụta.
Iji gbochie ikpo ọkụ ọ bụla n'ime igbe ahụ, emekwara m oghere abụọ na ala na n'elu igbe eletrik ka ikuku nwee ike ịgbasa na ya ma hapụ okpomọkụ ọ bụla.
Nzọụkwụ 6: Wụnye n'ime ụlọ obibi m
Iji tinye igbe eletrik, ejiri m teepu nwere akụkụ abụọ tinye igbe ahụ n'ahụ mgbidi na n'ebe okpomọkụ dị n'akụkụ ya.
Maka ugbu a, nke a bụ naanị ule na enwere m ike ikpebi na m chọrọ ịgbanwe ebe a ka achọghị m ịme oghere ọhụrụ na mgbidi ahụ.
Nzọụkwụ 7: Nzọụkwụ ọzọ
Ọ bụrụ na ihe niile na-aga nke ọma, enwere m ike ịkwalite ọrụ a ka ọ rụọ ọrụ dị ka igwe ọkụ maka stovu pellet m ka m wee nwee ike iwepụ nke azụmahịa ahụ kpamkpam. Ihe niile dabere ka onye enyemaka ụlọ ga-esi arụ ọrụ maka m n'ikpeazụ mana anyị ga-echere ịhụ nke ahụ.
Ka ọ dị ugbu a, ọ bụrụ na ị nwere mmasị na ọrụ a, jide n'aka na ị ga-elelekwa ndị ọzọ m na Instructables yana ọwa YouTube m. Enwere m ọtụtụ ndị ọzọ na-abata, biko tụlee ịdebanye aha gị.
