Internet of Things with Python

By: Gaston C. Hillar

Overview of this book

Internet of Things (IoT) is revolutionizing the way devices/things interact with each other. And when you have IoT with Python on your side, you'll be able to build interactive objects and design them. This book lets you stay at the forefront of cutting-edge research on IoT. We'll open up the possibilities using tools that enable you to interact with the world, such as Intel Galileo Gen 2, sensors, and other hardware. You will learn how to read, write, and convert digital values to generate analog output by programming Pulse Width Modulation (PWM) in Python. You will get familiar with the complex communication system included in the board, so you can interact with any shield, actuator, or sensor. Later on, you will not only see how to work with data received from the sensors, but also perform actions by sending them to a specific shield. You'll be able to connect your IoT device to the entire world, by integrating WiFi, Bluetooth, and Internet settings. With everything ready, you will see how to work in real time on your IoT device using the MQTT protocol in python. By the end of the book, you will be able to develop IoT prototypes with Python, libraries, and tools.

Chapter 9. Working with the Cloud

In this chapter, we will take advantage of many cloud services to publish and visualize data collected for sensors and to establish bi-directional communications between Internet-connected things. We will cover the following topics:

  • Publishing data to the cloud with dweepy and dweet.io

  • Building a web-based dashboard with freeboard.io

  • Sending and receiving data in real time through Internet with PubNub

  • Publishing messages with commands through the PubNub cloud

  • Working with bi-directional communications between IoT devices and other devices

  • Publishing messages to the cloud with a Python PubNub client

  • Using the MQTT protocol with Mosquitto and Eclipse Paho

  • Publishing messages to a Mosquitto broker with a Python client
