Android Based Home Automation System Using Bluetooth & Voice Command

grown at high speed. Also human lives have become much more dependent on electronic devices and appliances. It has thus led to the idea of developing a home automation system. This paper is about home automation system which would use a smartphone to enable any naïve user to operate all the appliances. The system has three components: an Arduino microcontroller for connecting the appliances, a Bluetooth module for signal transfer, and a smartphone running the Android application. The system also supports voice command for naïve users with command sensing. It decodes the user’s voice command and extracts the exact meaning of his command. The paper focuses on the features and design of the proposed system. The design is based on a standalone Arduino BT board and the appliances are connected to this board using relays.. The smartphone interacts with the Arduino via Bluetooth. The main aim of the system development is to be low cost and scalable according to the requirements. Password protection is being used for authentication.
