Android Based Home Automation Using AVR Microcontroller Through Wireless Communication

Developing human’s life activity with enhancing safety and security protocol Android-based automation is a vast alternative. This paper presents the design and implementation of an Android APP based home automation system which achieves multiple objectives about Password-based access control, induction motor speed and light intensity control, any electrical appliance switching ON/OFF and all unnecessary electrical appliances turn off automatically by counting person if no person is present. The work is constituted with a microcontroller, IR sensors, and HC05 Bluetooth module for confirming the wireless environment using Bluetooth technology and a software interconnection is also shown for proper using. Finally, this project eliminates the traditional method of controlling AC appliance and the process of individual involvement which makes life easier and faster in daily households need for everyone.
