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.

Hardware and software requirements


For this project, you will of course need an ESP8266 chip. As for most of this book, I used the Adafruit Huzzah ESP8266 module, but any ESP8266 module will work fine here.

As a sensor, I'll use the DHT11 sensor here just to illustrate the behavior of two out of the three scenarios in this chapter. However, you could use any sensor, or even use dummy data for this chapter. The goal is really to learn how to send notifications.

You will also need a 3.3V/5V FTDI USB module to program the ESP8266 chip.

Finally, you will also need some jumper wires and a breadboard.

This is a list of all the components that will be used in this chapter:

  • Adafruit ES8266 module (https://www.adafruit.com/products/2471)

  • FTDI USB module (https://www.adafruit.com/products/284)

  • DHT11 sensor (https://www.adafruit.com/products/386)

  • Breadboard (https://www.sparkfun.com/products/12002)

  • Jumper wires (https://www.sparkfun.com/products/9194)

On the software side, if it's not been done yet, you will...
