MQTT with ESP32 and DHT22 using Wokwi | Display on Node-Red Dashboard

In this video, we will see how to Simulate ESP32 Integration with DHT22 with Wokwi and send the temperature and humidity values to the Node-RED Dashboard using MQTT.
By the end of this video, you can see the real-time changes in Temperature and humidity of DHT22 on the Node-Red Dashboard using the MQTT publish and subscribe mechanism.

1. Setup ESP32 with DHT22 in Wokwi
2. Add the libraries needed
3. Upload the code
4. Setup the MQTT publish in code
5. Setup Node-Red
6. Create a Node-Red Dashboard to subscribe
7. View the Dashboard for the Temperature and Humidity values

This can be used as IoT projects for final year students
