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

The IoT Story

Energy sources and power management


Powering sensors and edge devices reveal a significant problem. When we consider that sensors and edge devices number in the billions, and the fact they will be used in very remote areas, power becomes a challenge. Furthermore, there will be IoT deployments where sensors will be buried undersea, or embedded into concrete infrastructures, further complicating power sources. In this section, we will explore the concepts of energy harvesting and power management. Both are very important concepts in the overall IoT story.

Power management

Managing power is a very broad topic, and spans software and hardware. It is important to understand the role of power management in a successful IoT deployment, and how to manage power efficiently for remote devices and long-lived devices. The architect must build a power budget for the edge device, which includes:

  • Active sensor power
  • Frequency of data collection
  • Wireless radio communication strength and power
  • Frequency of communication...
