(IOT Project) Tau Txais Cov Ntaub Ntawv Huab Cua Siv ESP8266 thiab Openweather API: 5 Cov Kauj Ruam

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:24

Hauv cov lus qhia no peb yuav tsim txoj haujlwm IOT yooj yim uas nqa cov ntaub ntawv huab cua ntawm peb lub nroog los ntawm openweather.com/api thiab tso tawm nws siv software ua.

Khoom siv:

1. Arduino
2. ESP8266 lossis lwm yam esp module
3. Arduino IDE Cov
4. Ua software
5. Cov qhob cij
6. Jumperwires Txiv neej rau Txiv neej thiab Txiv neej rau Poj Niam

Kauj ruam 1: Tau txais API Ntsiab Cai thiab URL Los Ntawm Openweather.org

1. Tsim tus account hauv https://openweathermap.org (Duab 1)
2. Tom qab koj nkag mus rau API yuam sij thiab koj yuav tau txais tus lej API raws li qhia hauv duab. (Duab 2)
3. Luam tus lej API thiab khaws nws hauv cov ntawv sau cia. (Duab 3)
4. Mus rau qhov kev xaiv API (Duab 4)
5. Mus rau API doc xaiv raws li qhia hauv duab (Duab 5)
6. Luam qhov url los ntawm thiab qhia thiab khaws nws hauv cov ntawv sau cia (Duab 6)

Kauj ruam 2: Daim duab txuas

Kauj Ruam 3: Arduino Code

Ua ntej theej cov cai no rau hauv Arduino nco ntsoov tias koj tau rub tawm ESP8266 pawg thawj coj mus rau hauv arduino lub tswv yim siv Boards manager.

Kauj Ruam 4: Ua Txoj Cai

Ua ntej khiav cov cai no rub tawm lub cim cim duab uas yuav siv los qhia huab cua. Thiab khaws cov duab thiab cov cai hauv tib daim nplaub tshev.
