Overview of this book

The ESP8266 Wi-Fi Module is a self contained System on Chip (SOC) with an integrated TCP/IP protocol stack and can give any microcontroller access to your Wi-Fi network. It is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. This book contains practical recipes that will help you master all ESP8266 functionalities. You will start by configuring and customizing the chip in line with your requirements. Then you will focus on core topics such as on-board processing, sensors, GPIOs, programming, networking, integration with external components, and so on. We will also teach you how to leverage Arduino using the ESP8266 and you'll learn about its libraries, file system, OTA updates, and so on. The book also provide recipes on web servers, testing, connecting with the cloud, and troubleshooting techniques. Programming aspects include MicroPython and how to leverage it to get started with the ESP8266. Towards the end, we will use these concepts and create an interesting project (IOT). By the end of the book, readers will be proficient enough to use the ESP8266 board efficiently.

Sending text message notifications

Getting text message notifications is probably the most reliable way to deliver real-time data and information. This is because the phone doesn't need an Internet connection to receive the notifications. With IFTTT, you can use your ESP8266 board to send text messages from your IoT projects to your phone. To demonstrate this, we will send text message notifications to a phone from the ESP8266, when the temperature measurement from the DHT11 sensor goes below 30 degrees Celsius.

Getting ready

You will use a hardware setup similar to the one in Automation with IFTTT. Also, you will have to set up the SMS service on IFTTT.

How to do it…

  1. Create a new applet on IFTTT and click on this to select the service that is going to be monitored. Select the Maker service and configure it (refer back to Automation with IFTTT).


    Remember to call the event temperature_low. If you change the event name, you have to also change it in the Arduino code.

  2. Once the setup is complete...
