5 $ Google Home Mini- Home Automation

About: Technical Trainer @Technical Hub

The main moto of this project is to develop a home automation system using an Node MCU board and Google home Mini. As technology is advancing so houses are also getting smarter. Modern houses are gradually shifting from conventional switches to centralized control system, involving remote controlled switches. Presently, conventional wall switches located in different parts of the house makes it difficult for the user to go near them to operate. Even more it becomes more difficult for the elderly or physically handicapped people to do so. Voice controlled home automation system provides a most modern solution with IOT Devices like Google home mini etc.

In order to achieve this, a relay module is interfaced to the Node MCU board at the receiver where loads are connected and google home mini will acts as your assistant . To operate any electrical appliance using Google home mini, you can simple say "Hey google, turn on kitchen light " .
