Practical Internet of Things with JavaScript

Overview of this book

In this world of technology upgrades, IoT is currently leading with its promise to make the world a more smarter and efficient place. This book will show you how to build simple IoT solutions that will help you to understand how this technology works. We would not only explore the IoT solution stack, but we will also see how to do it with the world’s most misunderstood programming language - JavaScript. Using Raspberry Pi 3 and JavaScript (ES5/ES6) as the base to build all the projects, you will begin with learning about the fundamentals of IoT and then build a standard framework for developing all the applications covered in this book. You will then move on to build a weather station with temperature, humidity and moisture sensors and further integrate Alexa with it. Further, you will build a smart wearable for understanding the concept of fall detection. You will then extend it with the 'If This Then That' (IFTTT) rules engine to send an email on fall detection. Finally, you will be working with the Raspberry Pi 3 camera module and surveillance with a bit of facial detection using Amazon Rekognition platform. At the end of the book, you will not only be able to build standalone exciting IoT applications but also learn how you can extend your projects to another level.

Agriculture and IoT


A report by Beecham Research predicts that the world population will reach 8 billion by 2025 and 9.6 billion by 2050, and in order to keep pace, food production must increase by 70% by 2050. Here is the report: https://www.beechamresearch.com/files/BRL%20Smart%20Farming%20Executive%20Summary.pdf

This means that we need to find quicker and more productive ways of farming. Land and resources are going to get scarcer as we keep moving toward 2050. This is when, given the resources, we would need to feed more mouths than ever before, unless a zombie apocalypse comes and all of us get eaten up by other zombies!

This is a very good opportunity for technology to provide solutions to make this happen. IoT has almost always been about smart homes, smart offices, and convenience, but it can do more than that. That is what we are going to cover in this chapter. We are going to build a smart weather station that a farmer can deploy in their farm to get real-time metrics such as temperature...
