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 MKR IoT Carrier

The MKR IoT Carrier is designed for the MKR board to be attached on top of it. It comes with the following sensors:

  • Five capacitive touch sensors
  • A temperature, humidity, and barometric pressure sensor
  • A six-axis inertial measurement unit
  • A color detection sensor
  • A gesture sensor

It also has an OLED display, two onboard relays, two analog Grove connectors, and one I2C Grove connector. You can see the MKR IoT Carrier in this video:

Let’s work with the MKR IoT Carrier to collect sensor data.

Project 2 – Collecting sensor data with the Arduino MKR IoT Carrier

In this project, we will use the MKR WiFi 1010 to connect to a wireless network and then fetch the time from an NTP server when the microcontroller starts up. Afterward, every minute, we will read the temperature, humidity, and pressure and display those on the OLED display. The code for this project is available on GitHub...
