Overview of this book

In our modern, internet-connected world, where billions of devices constantly collect and send data to systems to be stored and processed, it’s surprising how the intricacies of data transmission and storage are often overlooked in the IoT domain. With Arduino Data Communications, you'll bridge the knowledge gap and become an expert in collecting data from IoT sensors, transmitting data, and configuring your own databases. This book is an exploration of IoT’s inner workings, guiding you through the process of setting up an end-to-end system that you can employ to prototype your own IoT solutions, using easy-to-follow examples. It begins with a general overview of the Arduino ecosystem, acquainting you with various sensors and shields and unveiling the art of data collection. You’ll then explore data formats and methods to store data, both locally and on database servers. As you progress through the chapters, you’ll learn how to set up REST and MQTT infrastructure to communicate with databases and get hands-on with LoRaWAN, Ethernet, cellular, HC-12, and RS-485. The final chapters are your training ground for real-world projects, imparting the essential knowledge you need to tackle complex challenges with confidence. By the end of this Arduino book, you'll have seamlessly configured an end-to-end system, all while immersing yourself in practical scenarios that bring the world of IoT to life.

Implementing REST and MQTT Protocols for Communication

Database management systems (DBMSs) are good at storing and retrieving data, but they are not normally designed for communicating over the internet. Furthermore, while they can handle large amounts of data, they are not designed to handle this from thousands of sources. This is where REpresentational State Transfer (REST) and Message Queueing Telemetry Transport (MQTT) come in handy. These two protocols make it possible for us to build third-party applications to communicate with a DBMS at scale. You will be setting up REST and MQTT services in this chapter.

In this chapter, we are going to cover the following main topics:

  • Working with RESTful APIs in Node.js and JavaScript
  • Working with RESTful APIs in Python
  • Working with MQTT

By the end of this chapter, you will have set up infrastructure that makes it possible to communicate with your DBMS over a network or the internet.
