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.

Building a web-based dashboard with Freeboard


The dweet.io data sharing utility allowed us to easily publish data to the cloud with just a few lines of code. Now, we are ready to use dweet.io and our thing name as a data source to build a real-time web-based dashboard. We will take advantage of freeboard.io to visualize the data collected with the sensor and published to dweet.io in many gauges and make the dashboard available to different computers and devices all over the world. Freeboard.io allows us to build a dashboard by selecting data sources and dragging and dropping customizable widgets. Freeboard.io defines itself as a cloud-based service that allows us to visualize the Internet of Things. You can read more about freeboard.io in its Webpage: http://freeboard.io.

Tip

In our example, we will take advantage of the free services offered by freeboard.io and we won't use some advanced features that provide privacy for our dashboards but also require a paid subscription. Our dashboard will...
