Raspberry Pi and MQTT
Description
You'll dig into the details of MQTT, and learn more about the clients or devices you connect to your server. In particular, work with two very popular IoT development boards among project developers: ESP8266 and the ESP32 Dev Boards. You will also learn to build interactive dashboards on your Pi and control or monitor your client devices using another popular software - Node RED.
Finally, put your theory into practical use by creating two full-scale projects-an IoT weather station and a smart switch board. That's not all though, you will also learn how to host an MQTT server on an virtual cloud service. With all that mastered, find out how to proceed forward from there, what technologies to learn, and some project recommendations to polish or test your knowledge.
The future of IoT has the potential to be limitless. Add fully connected IoT devices to your own technology stacks from beginner to industrial levels with this book!What You'll Learn
