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.

Remote weather station project description

As stated before, we want to build an Android Things Remote weather station that acquires data from remote sensors connected to several IoT boards. In this project, the Android Things board acts as an MQTT client that collects data coming from remote sensors and visualizes it through an UI. In this context, the sensors are not connected physically to the Android Things board, but they are managed by other non-compatible IoT boards. In turn, these IoT boards exchange data with Android Things using MQTT. We will describe in more details what MQTT is and how to use it later. For now, it is enough to know that MQTT is a lightweight protocol that is widely used in M2M communication.

The following diagram describes the project architecture:

As you might already foresee, this project emulates the scenario where we have sensors and IoT boards physically placed somewhere far from the place where we collect data and analyze it. Therefore, this project architecture...
