Internet of Things with ESP8266

By: Marco Schwartz

Overview of this book

The Internet of Things (IoT) is the network of objects such as physical things embedded with electronics, software, sensors, and connectivity, enabling data exchange. ESP8266 is a low cost WiFi microcontroller chip that has the ability to empower IoT and helps the exchange of information among various connected objects. ESP8266 consists of networkable microcontroller modules, and with this low cost chip, IoT is booming. This book will help deepen your knowledge of the ESP8266 WiFi chip platform and get you building exciting projects. Kick-starting with an introduction to the ESP8266 chip, we will demonstrate how to build a simple LED using the ESP8266. You will then learn how to read, send, and monitor data from the cloud. Next, you’ll see how to control your devices remotely from anywhere in the world. Furthermore, you’ll get to know how to use the ESP8266 to interact with web services such as Twitter and Facebook. In order to make several ESP8266s interact and exchange data without the need for human intervention, you will be introduced to the concept of machine-to-machine communication. The latter part of the book focuses more on projects, including a door lock controlled from the cloud, building a physical Bitcoin ticker, and doing wireless gardening. You’ll learn how to build a cloud-based ESP8266 home automation system and a cloud-controlled ESP8266 robot. Finally, you’ll discover how to build your own cloud platform to control ESP8266 devices. With this book, you will be able to create and program Internet of Things projects using the ESP8266 WiFi chip.

Chapter 11. Cloud-Based Home Automation System

In this chapter, we are going to use everything we learned so far in the book, and apply it to the home automation field. We are going to build a simple but complete home automation system that we will completely control from the cloud, thanks to the ESP8266 Wi-Fi chip. The system will be composed of a motion sensor, a temperature and humidity sensor, and an LED dimmer. This way, it will mimic all the essential components of a real home automation system.

We are going to build three projects based on this system. We are first going to see how to simply control every component of the system using an online dashboard. Then, we are going to see how to send automated alarms to your phone when motion is detected in your home. Finally, we are going to see how to automate your home using IFTTT and the system we created. Let's start!
