(IOT loyihasi) ESP8266 va Openweather API yordamida ob -havo ma'lumotlarini oling: 5 qadam

2024 Muallif: John Day | [email protected]. Oxirgi o'zgartirilgan: 2024-01-30 13:22

Bu yo'riqnomada biz oddiy IOT loyihasini qurmoqchimiz, unda openweather.com/api saytidan shahrimiz ob -havo ma'lumotlarini olish va uni ishlov berish dasturi yordamida ko'rsatish.

Ta'minot:

1. Arduino
2. ESP8266 yoki boshqa har qanday esp moduli
3. Arduino IDE
4. Qayta ishlash dasturi
5. Non paneli
6. Jumper simlari erkakdan erkakgacha va erkakdan ayolgacha

1 -qadam: Openweather.org saytidan API kaliti va URL manzilini oling

1. Https://openweathermap.org saytida hisob yarating (1 -rasm)
2. Kirishdan so'ng API kalitlariga o'ting va rasmda ko'rsatilgandek API kalitini olasiz. (2 -rasm)
3. API kalitini nusxa ko'chiring va uni bloknot fayliga saqlang. (3 -rasm)
4. API variantiga o'ting (4 -rasm)
5. Rasmda ko'rsatilgandek API doc variantiga o'ting (5 -rasm)
6. Ko'rsatilgan va ko'rsatilgandan urlni nusxalash va bloknot fayliga saqlash (6 -rasm)

2 -qadam: ulanish diagrammasi

3 -qadam: Arduino kodi

Ushbu kodni Arduino -ga nusxalashdan oldin, ESP8266 kartasini taxtalar menejeri yordamida arduino ide -ga yuklaganingizga ishonch hosil qiling.

4 -qadam: kodni qayta ishlash

Ushbu kodni ishga tushirishdan oldin ob -havoni ko'rsatish uchun ishlatiladigan tasvir tasvirini yuklab oling. Va rasm va kodni bitta papkada saqlang.
