Internet of Things (IoT) with Arduino Uno, Raspberry Pi & NodeMCU

This book is written in a manner that is accessible and suitable for students. It also contains sample codes and a number of illustrative figures and examples. While elucidating architecture, design principles, hardware and software designs, the text primarily targets post-graduates and multidisciplinary undergraduates. The Internet of Things (IoT), which is the convergence of connecting people, things, data, and processes, is introduced in this book. It is radically altering our way of life, our businesses, and everything else. Experts predict that by 2025, up to 75 billion devices will be Internet-connected, with tablets, smartphones, computers, and smartwatches comprising less than one-third of that number. Alternative devices comprising the remaining two-thirds will include sensors, terminals, household appliances, thermostats, televisions, automobiles, production machinery, urban infrastructure, and numerous other things that have not been Internet-enabled in the past. The Internet of Things signifies an unprecedented paradigm shift in the future of global interaction. Comparable to how the World Wide Web and the subsequent generation of mobile devices linked computers to networks and individuals to the Internet and one another, the Internet of Things appears positioned to establish connections between machines, environments, virtual objects, and devices in ways that were previously conceivable only to science fiction authors.
