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.

MQTT

MQTT stands for Message Queue Telemetry Transport. It is an extremely lightweight messaging protocol based on the publish/subscribe model and favored for use with constrained devices, low bandwidth, or where the network is unreliable.

MQTT was developed by Dr. Andy Stanford Clark of IBM and Arlen Nipper of Arcom (now Eurotech) in 1999. It was designed with the purpose of minimizing the device's resource requirements and network bandwidth consumption, very high scalability, smaller code footprint, and also ensuring the delivery of messages/signals. These attributes of the MQTT protocol make it the right candidate for Internet of Things use cases where we have massive numbers of constrained devices with limited memory, network bandwidth, and less processing power.
