Implementation of a power saving home automation system prototype controlled by an Android mobile application

Abstract

The goal of this project is to implement a prototype for an energy saving domotic system which performs control from a native Android application. Automatic control done by the application is of type ON-OFF, which allows to activate or deactivate the energy saving actuators connected to the system’s microcontroller. The mobile application has also the ability to sense the physical magnitude of the temperature in real-time. The point-to-point full duplex communication between the mobile device and HC05 BT chipset, via Bluetooth wireless protocol, allows an efficient transmission of control from the first one to the Arduino UNO development board. This open-source hardware card uses the Atmel ATmega328 microcontroller family. The native mobile application was developed in Java, using ECLIPSE ADT as the open-source software development platform. U ser interface design was driven by a single goal; to make a safe, intuitive, and easyto-use tool to control the domotic system from a mobile device.
