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.

AWS Rekognition

Rekognition is one of the AI/machine learning services provided by AWS. This is basically a computer vision-based service, which allow us to do analysis of videos and images without having to write all the algorithms by ourselves. We just need to provide a video or image as input to the Rekognition service and it will identify objects, texts, people, scenes, and activities. It also provides an accurate facial analysis and recognition service.

AWS Rekognition is based on deep learning technology, which we have already discussed in an earlier section of this chapter.

It provides an easy-to-use API/SDK to implement solutions. Rekognition takes data from the S3 storage service to perform the analysis.

The common use cases for which Rekognition is used are as follows:

  • Searchable image and video libraries: This allows you to search huge volumes of videos and images...
