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.

Sending data via text message


We are now going to use the same hardware to make a completely different project. We'll use IFTTT again to send measurement data from the ESP8266 chip to your mobile phone:

  1. To do that, the first step is to connect the SMS channel to your IFTTT account. It's very simple, and you will just have to put in your phone number:

  2. It's now time to create a new recipe. This time, use data as the name of the event:

  3. Then, select the newly created SMS channel as the action of the recipe:

  4. Now, we are going to build a more complex message than earlier, because we want to have the information about the measurements done by the ESP8266 in the message. Thanks to IFTTT, it's very easy using the assistant to add values coming from the trigger channel:

  5. This is how your message should look at the end:

  6. Finally, create the recipe:

Now that the recipe is active, we can move on to the creation of the Arduino sketch. As there are many elements in common with the previous sketch, I will only detail...
