Overview of this book

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.

The internet

Before we dive into understanding communication protocols, let's understand how the internet works since it is the backbone in the concept of IoT.

The internet is a global network of computers/systems connected to each other. Each system/computer has a unique Internet Protocol (IP) address as its identifier over the internet. But how exactly does one system interact with another? Through a protocol stack. It is also referred to as the Transmission Control Protocol (TCP) or IP protocol stack.

This table will help you understand TCP/IP:

Application protocol

Specific to application such as FTP, email, HTTP, MQTT, Socket, and the others.

Transmission control protocol

It is a standard that defines how to establish and maintain a connection between applications so that data transmission can take place.
