2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

HNUB….. hnub no peb yuav kawm txog kev ntsuas qhov hnyav ntawm lub teeb thiab tshaj tawm qhov txiaj ntsig rau hauv THINGSAI IOT huab platform los ntawm kev siv ESP32.

Cov tseev kom ua qhov haujlwm no yog

1. ESP32 Development Board (Kuv tau siv ESP32 DEVKIT V1)

2. LDR sensor

3. Jumper Wires

4. Account hauv THINGSAI IOT PLATFORM

Kauj Ruam 1: Tsim thiab nkag mus rau THINGSIO Platform

Nkag mus rau THINGS AI tus account. Yog tias koj yog tus tshiab ces sau npe rau tus as khauj los ntawm nias lub pob sau npe thiab sau tag nrho cov ntawv pov thawj. Koj tus lej nyiaj yuav raug tsim thiab txij thaum ntawd los koj yuav tuaj yeem ua haujlwm ntawm huab platform thiab tsim koj txoj haujlwm tshwj xeeb

Kauj Ruam 2: Tsim Txoj Haujlwm Tshiab

Tom qab nkag mus rau hauv tus as khauj, los tsim qhov project tsuas yog nyem rau ntawm qhov haujlwm tshiab thiab tom qab ntawd muab lub npe project.

Kauj Ruam 3: Tsim Tus Ntaus Tshiab

tom qab tsim qhov project yam tom ntej uas koj yuav tsum tau ua yog tsim lub cuab yeej tshiab. Qhia lub npe ntaus ntawv thiab nkag mus rau tus lej ntaus ntawv txawm yog tus kheej lossis lub tshuab tsim.

Kauj Ruam 4: Txheeb Cov Khoom Parameter

Muab cov cuab yeej ntsuas thiab tom qab ntawd xaiv hom kev ntsuas

Kauj Ruam 5: Hloov Kho Tus Ntaus

Xaiv qhov ntsuas thiab tom qab hloov kho lub cuab yeej

Kauj ruam 6: Coding

Los ntawm cov qauv piv txwv xaiv cov cai ntawm esp32 luam nws thiab tom qab ntawd muab lo rau hauv arduino IDE thiab hloov qhov tsim nyog raws li qhov xav tau. Kuv tau muab cov cai hauv qab no

Kauj ruam 10: Serial Monitor

Qhov muaj txiaj ntsig tau txais ntawm cov ntawv saib xyuas tom qab ntawd lawv raug xa mus rau THINGSAI IOT Cloud platform.

Kauj ruam 11: Nyeem ntawv

Qhov no qhia pom qhov txiaj ntsig tau los ntawm pawg thawj coj esp32.

Kauj Ruam 12: Cov Duab Sawv Cev

Nov yog cov duab sawv cev ntawm cov txiaj ntsig tau txais. Ntawd yog qhov kawg ntawm kev qhia. Vam tias koj nkag siab. Ua Tsaug
