Hozirgi vaqtda IoT trendda va ko'plab mashinalarda bulut orqali yuklash va ma'lumotlarni tahlil qilish uchun ma'lumotlar mavjud. Kichik datchiklar bulutdagi ma'lumotlarni yangilaydi va boshqa uchida harakatlantiruvchi vosita ishlaydi, men IoT misolidan birini tushuntirmoqchiman.

Men ushbu maqolada va ESP8266 yordamida Thingspeak -ga ma'lumotlarni joylashtirish uchun ko'rsatma beraman.
