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.

Amazon S3 stands for a simple storage service, and it provides a storage facility for the internet. S3 allows to store and retrieve any amount of data from anywhere. There are multiple ways of storing and retrieving data, such as through the Command Line Interface (CLI), through the API/SDK, and through the AWS management console.

S3 stores data in the form of objects inside buckets. The object inside the bucket has a file and its metadata, which has information about the file. To store an object in S3, first we need to create a bucket, then upload the object (file), and after uploading we can set the access permission for that particular object inside the bucket. Apart from access, we can also set the geographical region (out of the available ones) in which the bucket should be placed. Figure 7.4 shows a general flow of task performed in S3:
