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 push notifications

Using IFTTT, you can easily send push notifications to your phone from your ESP8266-based IoT project. This is possible through the Pushover service. To demonstrate this, we will get a temperature measurement from the DHT11 sensor using the ESP8266 and send push notifications to an Android phone when the temperature goes below 30 degrees Celsius.

Getting ready

You will use the same setup as in the previous recipe, which includes a DHT11 sensor connected to an ESP8266 board. Also, download the Pushover app on your phone, create an account, and provide the name of your device.

How to do it…

  1. Log in to your IFTTT account and create a new applet.

  2. Set the Maker service as your This, as you did in the previous recipe. The event name will still be temperature_low. The Maker service configuration will be as follows:

  3. Once the Maker service is fully configured, proceed to set up the That service. The service we will be using to send the push notifications is the Pushover service...
