▶Book Description
This book is designed to introduce you to IoT and Raspberry Pi 3. It will help you create interesting projects, such as setting up a weather station and measuring temperature and humidity using sensors; it will also show you how to send sensor data to cloud for visualization in real-time. Then we shift our focus to leveraging IoT for accomplishing complex tasks, such as facial recognition using the Raspberry Pi camera module, AWS Rekognition, and the AWS S3 service. Furthermore, you will master security aspects by building a security surveillance system to protect your premises from intruders using Raspberry Pi, a camera, motion sensors, and AWS Cloud. We'll also create a real-world project by building a Wi-Fi – controlled robot car with Raspberry Pi using a motor driver circuit, DC motor, and a web application.
This book is a must-have as it provides a practical overview of IoT’s existing architectures, communication protocols, and security threats at the software and hardware levels—security being the most important aspect of IoT.

▶What this book covers
⦁ Chapter 1, Introduction to IoT, provides an introduction to Internet of Things, a little background, the current scenario, the future of IoT, as well as its impact on our life. Here, you will also learn about the architecture of an IoT ecosystem and its application and benefits in different fields.
⦁ Chapter 2, Know Your Raspberry Pi, introduces you to Raspberry Pi. Why is this one of the most popular boards for learning and building IoT projects? Here, we will learn about the anatomy of Raspberry Pi, GPIO, and other functionalities. Setting it up includes installing an OS, getting comfortable with Shell commands and its UI, and connecting it to a network/Wi-Fi.
⦁ Chapter 3, Let's Communicate, makes Raspberry Pi communicate with the cloud/server using protocols such as HTTP and MQTT. We will demonstrate how data transfers between Pi and the cloud.
⦁ Chapter 4, Weather Station, sets up Raspberry Pi as a weather station, which will measure weather conditions and send the data to a Google spreadsheet for analysis. We will measure the temperature and humidity using sensors connected to GPIO programmatically.
⦁ Chapter 5, Controlling the Pi, explains how to control actuators, LEDs, and other devices connected to Pi remotely using web apps.
⦁ Chapter 6, Security Surveillance, explains how to build your own security surveillance system to protect your home/premises from intruders. We will use Raspberry Pi, a camera module, a motion sensor, and cloud to complete this project.
⦁ Chapter 7, Image Recognition, explains how we can leverage IoT to accomplish complex tasks such as face recognition using Raspberry Pi, camera module, AWS Rekognition, and AWS S3 service.
⦁ Chapter 8, Bot Building, shows how to build a Wi-Fi-controlled robot car using Raspberry Pi. We will use a motor-driver circuit, a DC motor, and a web application to complete the task.
⦁ Chapter 9, Security in IoT, talks about why security is the most important aspect of IoT, what the existing threats at the software and hardware level are, and how we can ensure security in our IoT using various practices.
