In this project, we will implement remote control LED lights via NodeMCU(ESP8266) and MQTT broker, and use the Arduino IDE to program NodeMCU ESP8266.

This article will introduce how to use the data template in the sink to achieve "secondary processing" of the analysis results.

This project will implement connecting ESP8266 to a free public MQTT broker and programming ESP8266 by using Arduino IDE.

This example will demonstrate how to report the temperature and humidity data collected by the DHT11 sensor to the MQTT service in the cloud through the MQTT protocol and the NodeMCU based on ESP8266 , and show how the application subscribes to and processes the data.
