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.

Working with The Things Network

TNN is a public LoRaWAN network server that makes it easy to register gateways, applications, and devices (nodes) and to transmit data from nodes to the network server via the registered gateways.

TTN enforces a few constraints that you need to be aware of before you start using it. These include the following:

  • Only transmitting binary data
  • Keeping data sizes as small as possible
  • Avoiding continuous data transmission
  • Utilizing an Adaptive Data Rate (ADR)
  • Avoiding downlink messages if possible
  • Avoiding confirmed uplinks

You can get started by visiting and creating an account. When you log in, you will be met with a console that lets you manage either applications or gateways. The top of the console looks like the following.
