BeagleBone Home Automation Blueprints

By: Rodolfo Giometti

Overview of this book

BeagleBone is a microboard PC that runs Linux. It can connect to the Internet and can run OSes such as Android and Ubuntu. BeagleBone is used for a variety of different purposes and projects, from simple projects such as building a thermostat to more advanced ones such as home security systems. Packed with real-world examples, this book will provide you with examples of how to connect several sensors and an actuator to the BeagleBone Black. You’ll learn how to give access to them, in order to realize simple-to-complex monitoring and controlling systems that will help you take control of the house. You will also find software examples of implementing web interfaces using the classical PHP/HTML pair with JavaScript, using complex APIs to interact with a Google Docs account, WhatsApp, or Facebook. This guide is an invaluable tutorial if you are planning to use a BeagleBone Black in a home automation project.

Setting up the hardware

About the hardware, there are at least two major issues to be pointed out:

  • Power supply: We have two different voltages to use due to the fact the water pump, the lamp, and the cooler are 12V powered, while the other devices are 5V/3.3V powered. So, we have to use a dual output power source (or two different power sources) to power up our prototype.

  • Interface: The second issue is about using a proper interface circuitry between the 12V world and the 5V one in such a way that it doesn't damage the BeagleBone Black or other devices. Let me point out that a single GPIO of the BeagleBone Black can manage a voltage of 3.3V, so we need a proper circuitry to manage a 12V device.

Setting up the 12V devices

As just stated, these devices need special attention and a dedicated 12V power line which, of course, cannot be the one we wish to use to supply the BeagleBone Black. On my prototype, I used a 12V power supplier that can supply a current till 1A. These characteristics should...
