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

A basic Python program to pull data from the cloud


In Chapter 11, Writing Python Programs Using Raspberry Pi, we introduced a package called weather-api that allows us to access the Yahoo! Weather web service. In this section, we will wrap up the Weather object from the weather-api package in our own class. We will reuse the name CurrentWeather for our class. After testing out our CurrentWeather class, we will utilize the Sense Hat Emulator in Raspbian and build a weather information ticker.

Accessing the web service

We will start out by modifying our CurrentWeather class to make web service calls to Yahoo! Weather through the weather-api package:

  1. Open up Thonny from Application Menu | Programming | Thonny Python IDE.
  2. Click on the New icon to create a new file.
  3. Type the following:
from weather import Weather, Unit

class CurrentWeather:
     temperature = ''
     weather_conditions = ''
     wind_speed = ''
     city = ''

     def __init__(self, city):
         self.city = city
         weather...
