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.

Discovering other types of shields

Arduino provides various shields. Let’s place some of these in categories.

Providing additional connectivity

MKR boards come in different variants, providing different connectivity options. One popular connectivity option is Wi-Fi. There are other connectivity options that you will not find as MKR boards, but you can get a shield for some of these:

  • The MKR ETH Shield will let you plug an Ethernet cable into your MKR board. This is useful for environments where wireless signals would interfere with the operation of other machinery, such as in a medical setting. This shield also provides an SD card slot for data logging purposes.
  • The MKR 485 Shield will let you connect to a legacy industrial system and communicate with it. This shield lets you implement communications using the serial protocol.

Communicating with automobiles

The MKR CAN Shield will let you connect to the brains of an automobile using something called...
