IOT Based Home Automation (with Google assistant )

Abstract: The idea behind Google assistant-controlled Home automation is to control home devices with
voice. On the market there are many devices available to do that, but making our own is awesome. In this
project, the Google assistant requires voice commands. Webhook account which is a cloud based free IoT
web server used to create virtual switches, is linking to IFTTT website abbreviated as “If This Than That”
which is used to create if else conditional statements. The voice commands for Google assistant have been
added through IFTTT website. In this home automation, as the user gives commands to the Google
assistant, Home appliances like Bulb, Fan and Motor etc., can be controlled accordingly. The commands
given through the Google assistant are decoded and then sent to the microcontroller, the microcontroller in
turn control the relays connected to it. The device connected to the respective relay can be turned On or
OFF as per the users request to the Google Assistant. The microcontroller used is NodeMCU (ESP8266)
and the communication between the microcontroller and the application is established via Wi-Fi (Internet).
