Na fara bincika Mataimakin Gida kuma don samun damar fara ƙirƙirar wasu kayan aiki da kai, Ina buƙatar samun yanayin zafin jiki da ƙimar zafi na yanzu daga falo na a ciki don in yi aiki da su.
Akwai hanyoyin kasuwanci don wannan amma ina so in gina kaina don in iya koyon yadda Mataimakin Gida ke aiki da yadda ake saita na'urori na al'ada tare da shi da ESPhome.
Dukkanin aikin an gina shi akan PCB na al'ada wanda na tsara azaman dandamali na aikin NodeMCU sannan abokaina suka ƙera su a PCBWay. Kuna iya yin odar wannan allo da kanku kuma ku sami ƙera guda 10 akan $5 kawai a: https://www.pcbway.com/project/shareproject/NodeMCU_Project_Platform_ce3fb24a.html

Mataki 1: Kwamfutar PCB
Na tsara wannan PCB don zama dandamalin aikin bayan da na kashe lokaci mai yawa don sayar da ayyukan NodeMCU na al'ada akan PCBs.
PCB yana da matsayi don NodeMCU, na'urorin I2C, na'urorin SPI, relays, na'urar firikwensin DHT22 da UART da kuma wutar lantarki na HLK-PM01 wanda zai iya kunna aikin daga tashar AC.
Kuna iya duba bidiyon tsari da tsari akan tashar YT ta.
Mataki na 2: Sayar da kayan aikin
Tun da ba na son siyar da NodeMCU kai tsaye zuwa PCB, na yi amfani da fil ɗin mata na siyar da su da farko don haka zan iya toshe Node MCU a cikinsu.
Bayan masu kai, na siyar da tashoshi na dunƙule don shigar da AC da kuma na 5V da 3.3V.
Na kuma sayar da kan kai don firikwensin DHT22 da wutar lantarki na HLK-PM01.
Mataki na 3: Gwada Voltages da Sensor
Tun da wannan shine karo na farko da na yi amfani da wannan PCB don aiki, Ina so in tabbatar da cewa ban lalata wani abu ba kafin haɗa Node MCU. Ina so in gwada allo voltages cewa komai yayi daidai. Bayan gwajin farko na fitar da layin dogo na 5V ba tare da an shigar da Node MCU ba, na shigar da Node MCU don tabbatar da cewa yana samun 5V kuma yana samar da 3.3V daga mai sarrafa kan sa. A matsayin gwaji na ƙarshe, na loda azamanampLe sketch don firikwensin DHT22 daga ɗakin karatu na DHT Stable don haka zan iya tabbatar da cewa DHT22 yana aiki da kyau kuma zan iya samun nasarar karanta yanayin zafi da zafi.
Mataki 4: Ƙara Na'urar zuwa Mataimakin Gida
Tun da komai yayi aiki kamar yadda aka zata, sai na ci gaba da shigar da ESPhome zuwa saitin Mataimakin Gida na kuma na yi amfani da shi don ƙirƙirar sabuwar na'ura da loda firmware ɗin da aka bayar zuwa NodeMCU. Na sami matsala ta amfani da web loda daga ESPhome zuwa toka firmware da aka bayar amma a ƙarshe, na zazzage ESPhome Flasher kuma na sami damar loda firmware ta amfani da wannan.
Da zarar an ƙara firmware na farko a na'urar, na gyara .yamlle don shi don ƙara sashin kulawa na DHT22 kuma na sake loda firmware, yanzu ina amfani da sabuntawar iska daga ESPhome.
Wannan ya tafi ba tare da tsangwama ba kuma da zarar an gama shi, na'urar ta nuna ma'aunin zafi da zafi a cikin dashboard.
Mataki 5: Yi Wurin Dindindin
Ina son a dora wannan na'urar a hankali kusa da ma'aunin zafi da sanyio na yanzu wanda nake da shi a gidana don murhun pellet don haka na yi amfani da akwatin junction na lantarki don yin shinge. Ana ɗora firikwensin DHT22 a cikin rami da aka yi a cikin akwatin lantarki don haka zai iya lura da yanayin da ke waje na akwatin kuma kada wani zafi da ke fitowa daga wutar lantarki ya shafa.
Don hana duk wani zafi da ke cikin akwatin, na kuma yi ramuka biyu a ƙasa da saman akwatin lantarki ta yadda iska za ta iya zagayawa ta cikinsa kuma ta saki kowane zafi.
Mataki na 6: Hau a cikin Daki Na
Don hawa akwatin lantarki, na yi amfani da tef mai gefe biyu don manne akwatin a bango da ma'aunin zafi da sanyio kusa da shi.
A yanzu, wannan gwaji ne kawai kuma zan iya yanke shawarar cewa ina so in canza wannan wurin don haka ba na son yin sabon ramuka a bango.
Mataki na 7: Matakai na gaba
Idan komai ya yi kyau, zan iya haɓaka wannan aikin don yin aiki a matsayin ma'aunin zafi da sanyio don murhun pellet ɗina don in cire na kasuwanci gaba ɗaya. Duk ya dogara da yadda Mataimakin Gida zai yi aiki da ni a cikin dogon lokaci amma za mu jira don ganin hakan.
A halin yanzu, idan kuna son wannan aikin, ku tabbata kuma ku duba sauran nawa akan Instructables da tashar YouTube ta. Ina da wasu da yawa suna shigowa don haka don Allah kuyi subscribing shima.
