Internet of Things with Python

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.

Setting up devices in Intel IoT Analytics


The image that we have been using to boot our Intel Galileo Gen 2 board includes a local agent for Intel IoT Analytics preinstalled. Unless we have made specific changes to the Yocto Linux meta distribution to disable specific components, we will have the agent running as a daemon on the device. The agent includes the iotkit-admin command-line utility that allows us to perform specific interactions with Intel IoT Analytics. We will use this command-line utility to perform the following tasks:

  • Test the proper communication with Intel IoT Analytics

  • Obtain the device id

  • Activate a device

  • Register three time series components for the device.

  • Send test observations

First, we will check whether the iotkit-admin command-line utility can establish proper communication with Intel IoT Analytics. We just need to run the following command in the SSH terminal:

iotkit-admin test

If the connection is successful, we will see lines similar to the following ones. The last...
