Smart Home Automation using Voice Command

Abstract

The aim of this project is to design and develop a” Smart Home Automation System using Voice Command” to control household appliances seamlessly. Traditional home automation systems can be expensive and require manual input. This project introduces a cost-effective and highly accessible prototype that utilizes Internet of Things (IoT) concepts, Bluetooth communication, and Voice Recognition technology. The system’s core architecture consists of an Arduino microcontroller, an HC-05 Bluetooth module, and a multi-channel Relay module connected to standard home appliances (like lights and fans). The user interacts with the system using an Android smartphone equipped with a voice recognition application (such as Google Assistant). The voice commands are converted into text and transmitted over Bluetooth to the HC-05 module. The Arduino processes these incoming serial data commands and triggers the corresponding relays to turn the connected devices ON or OFF. This project successfully demonstrates a reliable, cheaper, and user-friendly alternative to expensive smart home solutions, making home automation accessible to everyone, including the elderly and physically disabled.
