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.

Leveraging Various Sensors for Data Acquisition

In the previous chapter, you learned how to blink an LED. Doing that lets the microcontroller interact with its environment. You were using the LED as an actuator to control the environment. With Arduino, you can also read the environment using sensors. Sensors convert the state of the environment into an electrical signal. You can read these signals using input and output pins.

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

  • Learning about microcontroller input and output pins
  • Discovering sensors

By the end of this chapter, you will have learned about various sensors and the various ways in which you can collect data. You will find this knowledge to be useful when you encounter new sensors as you go about your daily activities. The knowledge you will acquire in this chapter will come in handy for collecting data in future projects.
