Mastering IOT

By: Colin Dow, Perry Lea

Overview of this book

The Internet of Things (IoT) is the fastest growing technology market. Industries are embracing IoT technologies to improve operational expenses, product life, and people's well-being. We’ll begin our journey with an introduction to Raspberry Pi and quickly jump right into Python programming. We’ll learn all concepts through multiple projects, and then reinforce our learnings by creating an IoT robot car. We’ll examine modern sensor systems and focus on what their power and functionality can bring to our system. We’ll also gain insight into cloud and fog architectures, including the OpenFog standards. The Learning Path will conclude by discussing three forms of prevalent attacks and ways to improve the security of our IoT infrastructure. By the end of this Learning Path, we will have traversed the entire spectrum of technologies needed to build a successful IoT system, and will have the confidence to build, secure, and monitor our IoT infrastructure. This Learning Path includes content from the following Packt products: Internet of Things Programming Projects by Colin Dow Internet of Things for Architects by Perry Lea

Smart IoT endpoints


So far, we have examined very simple sensors that simply return information in a binary or analog form that must be sampled. There are, however, IoT devices and sensors that have substantial processing power and performance for the tasks they undertake. Smart sensors include devices such as video cameras and vision systems. Smart sensors can include substantial amounts of processing in the form of high-end processors, digital signal processors, FPGAs, and custom ASICs. In this section, we will explore the details of one form of smart sensor: a vision system.

Vision system

In contrast with the simple sensors explored earlier, vision systems are much more complex, which results in substantial hardware, optics, and imaging silicon. Vision systems start with a lens that observes a scene. A lens provides focus, but also provides more light saturation to the sensing element. In modern vision systems, one of two types of sensing elements is used: charge-coupled devices (CCD),...
