Misplaced Experience: ESP8266 NodeMCU Preface after Previous Project And later learning, I feel I can start a new project Liao. So, I suddenly have an idea: beside me, there is not only an ESP8266-NodeMCU (a board that can be connected to the Internet), but also a DHT11 sensor to see if the data can go to the cloud. This is also an imp ...
