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.

Utilizing Various Communication Technologies

We have set up infrastructure that lets us communicate with our databases over a network such as a Local Area Network (LAN) or over the internet. This chapter goes into detail about the choice of how we might communicate with these networks. You will learn about the various communication options based on the distance of your device from the closest radio antenna, and you will complete two projects that illustrate communicating over a Wi-Fi network to a REST endpoint.

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

  • Utilizing short-range communications
  • Utilizing medium-range communications
  • Utilizing long-range communications
  • Communicating with REST APIs

By the end of this chapter, you will have gained clarity about what communication technology to choose based on the distance that you need to cover. You will also have taken sensor readings and sent them to a REST API endpoint over Wi-Fi.
