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.

Storing Data Collected from Sensors

In the previous two chapters, we learned how to collect data from various sensors. However, the best we have done is display the information on a screen. It’s a waste to collect all of that data and not store it. Let’s look at how we can store the data that we are collecting. By the end of this chapter, you will know how to store data in files and various file formats that are in common use, set up a database, and write queries to read data out of a database. The data that you store will be useful for analysis in the future, usually by data analysts. For example, if you collect and store temperature and humidity data from different weather stations over a certain period, then that data can be used to analyze weather patterns.

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

  • Storing data
  • Working with flat files
  • Working with databases
