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.

Receiving alerts via push notifications


In the last project of the chapter, we are going to see how to send a third type of notification: push notifications. These are perfect for important alerts, as they will show up right on your phone when they're triggered.

To do so, we'll be using an application called Pushover that exists for iOS and Android. You first need to create an account at:

https://pushover.net/

Inside the Pushover dashboard, you'll need to get the API key; you'll need it in a moment to link Pushover to your IFTTT account.

Inside IFTTT, you can now connect the Pushover channel:

Now, we are ready to create the final recipe for this chapter. As the event name, this time choose alert:

Then, as the action channel, select the Pushover channel:

As the message for the push notification, you can choose what you want, for example a message saying that the humidity is too high:

Finally, save the recipe, which should now appear on your dashboard:

Let's now configure the ESP8266 board. As the...
