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.

Using MQTT with Mosquitto and Eclipse Paho


Mosquitto is an open source message broker that implements the versions 3.1 and 3.1.1 of the MQTT protocol, and therefore, allows us to work with messages using the publish/subscribe model. Mosquitto is an iot.eclipse.org project and is provided with the Eclipse Public Project (EPL)/EDL license. The following is the Web page for Mosquitto: http://mosquitto.org.

The Eclipse Paho project provides an open source client implementation of MQTT. The project includes a Python client, also known as the Paho Python Client or Eclipse Paho MQTT Python client library. This Python client has been contributed from the Mosquitto project and was originally the Mosquitto Python Client. The following is the Web page for the Eclipse Paho project: http://www.eclipse.org/paho. The following is the Web page for the Eclipse Paho MQTT Python client library, that is, the paho-mqtt module: https://pypi.python.org/pypi/paho-mqtt/1.1.
