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

As just stated, in this project we need two different kind of sensors: one to detect when the washing machine starts/stop, and one to detect when someone enters/exits the laundry room. The former task can be achieved by using a sound detector, that is, a device that is able to measure the environment sound level; while the latter task can be achieved by using a light sensor, that is, a device that is able to measure the environment light. Both these signals can be compared with thresholds in order to detect our relevant events.

When the washing machine is running, we should measure a high sound level for a long amount of time; while it is not running, the environment sound should be near to zero for a long time. On the other hand, we can assume that the person designed to pick up the washed clothes has to turn the light on in the laundry room, while the light is normally turned off when there is nobody in the room.
