This is the 3rd video of How to MQTT series. In this video, we will learn how to subscribe and publish MQTT messages using ESP8266 (NodeMcu). We will use the Raspberry pi as Local mosquitto MQTT broker which we created in the last video.

We will read the temperature and humidity values from a DHT11 sensor using Nodemcu and publish it on topic "data", raspberry pi will subscribe to that topic and receive that data. So this can also be considered as "Raspberry pi Esp8266 Wireless communication" or "NodeMcu Raspberry pi IoT".
