In this project, we will learn how to make IoT Based Home Automation Project using Google Firebase, ESP8266 – 01 & Atmega328p. By Home Automation we mean controlling home appliances like lights, fans, or anything with internet-connected relays.

Earlier we learned about Home automation using Blynk Application, WebServer. In this project, we will use Google Firebase. 

Google Firebase is a Google-backed application development software used for creating, managing, and modifying data generated from any android/IOS application, web services, IoT sensors & Hardware. To learn more about the Google Firebase Console, you can read the official Google Firebase Documentation from Google Firebase.

We will also learn to design a Home Automation Android Application using Kodular.io. Using the Firebase Host & Authentication Key, we will connect the Android Application and ESP8266-01 with Google Firebase Realtime Database. So whenever we turn ON/OFF the switches from the App the changes will be updated in the Firebase Database and our ESP8266-01 will be able to read any changes in the Firebase Database then the data will be transmitted to Atmega328 via UART then Atmega328 will toggle the GPIO Pins thus turning ON/OFF the appliances connected to Relay.
