Kauj Ruam 1: Daim duab Circuit Court

Qhov no yog daim duab qhia kev ua tiav rau qhov IoT raws txoj haujlwm hauv tsev hauv tsev.

Kuv tau siv NodeMCU los tswj cov qauv xa tawm. Kuv tau txuas nrog DHT11 qhov ntsuas kub & av noo thiab LDR los tswj kev xa rov qab raws li chav sov thiab teeb pom kev ib puag ncig. Muaj plaub lub khawm txuas nrog NodeMCU xws li, S1, S2, CMODE, RST. S1 & S2 los tswj cov txheej txheem xa tawm ntawm tus kheej CMODE los hloov Hom (Phau Ntawv Hom, Hom Pib) RST kom rov pib dua NodeMCU Kuv tau muab 12V rau tus qauv xa tawm thiab siv 7805 tus tswj hluav taws xob los muab 5v rau NodeMCU.

Kauj Ruam 2: Ua Lub Circuit Court ntawm Breadboard rau Kev Xeem

Ua ntej tsim PCB, thawj zaug kuv tau ua lub Circuit Court ntawm lub khob cij rau kev sim. Thaum ntsuas, kuv tau tshaj tawm cov cai rau NodeMCU tom qab ntawd sim tswj hwm kev xa rov qab nrog lub laub khawm, Blynk App, ntsuas kub, thiab LDR.

Rub daim ntawv txuas rau txoj haujlwm NodeMCU no.

Kuv tau hais tag nrho qhov txuas ntawm cov tsev qiv ntawv xav tau hauv cov cai.

Kauj Ruam 3: Nruab Blynk App

Nruab Blynk App los ntawm Google ua si tom khw lossis App khw tom qab ntxiv tag nrho cov cuab yeej xav tau los tswj cov qauv xa tawm thiab saib xyuas qhov kub thiab txias. Kuv tau piav qhia txhua yam hauv cov vis dis aus qhia.

Kuv tau siv 3 khawm widgets los tswj cov qauv xa tawm thiab hloov hom. Thiab 2 ntsuas cov cuab yeej los saib xyuas qhov kub thiab txias.

Kauj Ruam 4: Hom Sib Txawv ntawm Smart Relay Module

Peb tuaj yeem tswj hwm kev xa xov ntse hauv 2 hom:

1. Phau ntawv hom

2. Hom pib

Peb tuaj yeem hloov pauv hom yooj yim nrog khawm CMODE haum rau ntawm PCB lossis los ntawm Blynk App.

Kauj ruam 5: Phau Ntawv Hom

Hauv phau ntawv hom, peb tuaj yeem tswj hwm qhov hloov pauv los ntawm S1 & S2 laub-khawm lossis los ntawm Blynk App.

Peb tuaj yeem saib xyuas qhov xwm txheej ntawm lub sijhawm tiag tiag ntawm cov hloov pauv los ntawm Blynk App. Thiab peb tseem tuaj yeem saib xyuas qhov ntsuas kub thiab av noo ntawm OLED zaub thiab Blynk App li koj pom hauv daim duab. Nrog Blynk App, peb tuaj yeem tswj cov qauv xa tawm los ntawm txhua qhov chaw yog tias peb muaj internet ntawm peb lub xov tooj.

Kauj Ruam 6: Pib Hom

Hauv Hom pib, tus qauv xa tawm tswj los ntawm DHT11 sensor thiab LDR.

Peb tuaj yeem teeb tsa qhov kev txiav txim siab yam tsawg kawg nkaus thiab qhov siab tshaj plaws ntawm qhov kub thiab lub teeb. Hauv Hom pib thaum chav sov hla dhau qhov ntsuas kub tshaj plaws ua ntej tshaj qhov hloov pauv-1 tig rau thiab thaum chav sov dhau los ua qis dua qhov ntsuas kub tsawg kawg nkaus ua ntej qhov kev xa tawm-1 hloov mus.

Ib txoj hauv kev zoo ib yam thaum lub teeb qib qis dua qhov relay-2 tig rau thiab thaum lub teeb txaus, qhov relay-2 tig tawm ncaj qha. Kuv tau piav qhia ntxaws hauv cov vis dis aus qhia.

Kauj Ruam 7: Tsim PCB
