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

In this project, we are going to use two analog sensors, two digital sensors, and a webcam to take the pictures. The analog sensors are connected to two different ADC channels inputs (as in the previous chapter). The contactless external temperature sensor uses an I2C bus to communicate with the BeagleBone Black, while the waterproof internal temperature sensor uses a 1-Wire bus. Finally, the webcam is connected via the USB bus.

As in the previous chapter, I can add some actuators to flood water the plant and so on; but due to lack of space, I decided to leave these tasks to the reader as an exercise.

Connecting the moisture sensor

The moisture sensor is the device shown in the following image:


The device can be purchased from, or by surfing the Internet.

This device is quite similar to the water sensor presented in Chapter...
