Voice Controlled Smart Home Automation System Using Bluetooth Technology

Abstract

Innovation is not a destination; it is a journey to explore. Smart home appliances are being introduced into our day-to-day lives and they have a vast future opportunity. To control these appliances, people are looking for new technologies. Bluetooth is a convenient way of wireless communication within a short distance. In this research work, an Android application-based Bluetooth-controlled smart home automation system has been introduced. A programmable Arduino Uno is the controlling heart that works based on programming commands. A Bluetooth module (HC-05) is used for wireless connectivity and a relay circuit for switching. An interactive Android graphical user interface (GUI) has been developed by adding touch and voice command features for those who are blind and unable to move easily. A speech recognition feature has also been added to the Android application. English and Bangla are two languages that have been integrated into the programming so that English is taught and local Bengali people can easily control home appliances by using voice command.
