SMART HOME AUTOMATION

Abstract

In recent decades, home automation systems have gained substantial popularity, and their proliferation continues to be a topic of discussion. Nowadays, the majority of home automation setups typically involve a smartphone and a microcontroller. These systems rely on smartphone applications to manage and supervise household appliances using various communication methods. This paper introduces a concept for home automation through voice commands utilizing Google Assistant. Considering that smartphones are now almost ubiquitous, with a cost assumption of $10 USD, it is possible to control up to 8 appliances via Google Assistant. The paper details the development of such a system, which utilizes common household appliances. The user issues natural language voice commands to Google Assistant, and these commands are deciphered and transmitted to the microcontroller using applications like IFTTT (If This Then That) and Blink. The microcontroller, a Node MCU (ESP8266), controls the connected relays as necessary, switching the associated devices on or off based on the user's instructions through Google Assistant. Communication between the microcontroller and the application is established via Wi-Fi over the internet.
