ESP8266 MQTT Cloud Tutorial: Publish & Subscribe IoT Data with DHT11 🌐

This is the 4th video of How to MQTT series. In this video, we will learn how to subscribe and publish MQTT messages using ESP8266 (NodeMcu) to MQTT Cloud. This video is sponsored by RYC1001 MQTT cloud by Reyax technology.

We will read the temperature and humidity values from a DHT11 sensor using Nodemcu and publish it on MQTT Cloud. The GUI made on Python will subscribe to the data and will show temp and humidity values.
