Overview of this book

Android Things makes developing connected embedded devices easy by providing the same Android development tools, best-in-class Android framework, and Google APIs that make developers successful on mobile. With this book, you will be able to take advantage of the new Android framework APIs to securely build projects using low-level components such as sensors, resistors, capacitors, and display controllers. This book will teach you all you need to know about working with Android Things through practical projects based on home automation, robotics, IoT, and so on. We’ll teach you to make the most of the Android Things and build enticing projects such as a smart greenhouse that controls the climate and environment automatically. You’ll also create an alarm system, integrate Android Things with IoT cloud platforms, and more. By the end of this book, you will know everything about Android Things, and you’ll have built some very cool projects using the latest technology that is driving the adoption of IoT. You will also have primed your mindset so that you can use your knowledge for profitable, practical projects.

Chapter 3. How to Make an Environmental Monitoring System

This chapter describes how to build an environmental monitoring system. We want to build a complex IoT system, using Android Things, that measures some physical environment properties. Furthermore, in this Android Things project, we will use RGB LED, introduced in Chapter 1, Getting Started with Android Things, and a single color LED to visually represent the environment conditions. To do it, we will use a different class of sensors. While in the previous chapter we learned how to use two-states sensors, in this chapter we will use more complex sensors that require different connections and pins. In more detail, this chapter focuses on learning how to use I2C with Android Things.

Moreover, the main topics covered in this chapter are:

  • How to use I2C sensors with Android Things
  • How to read data from sensors using Sensor Manager
  • How to visualize the data acquired using LEDs
  • Overview of I2C protocol
  • Custom I2c driver
