Android Based Home Automation

This Project presents the overall design of Home Automation System (HAS) with low cost and wireless remote control. This system is designed to assist and provide support so as to fulfill the needs of old age and physically challenged people at home. Also, the smart home concept in the system improves the standard of living at home. The main system implements Wireless Bluetooth technology to provide remote access from Smart Phone. The design has switches and provides more safety control features. All the Switches Status is synchronized with the Control System by every user interface indicates its real time status of each switches independently. This system is very useful to control electrical appliances and devices in house with relatively low-cost design, user friendly interface and straightforward for installation. Due to the advancement of wireless technology, there are several different connections are introduced such as GSM, WIFI, ZIGBEE, and Bluetooth. Each of the connection has their own unique specifications and applications. Among the four popular wireless connections that often implemented in HAS project, Bluetooth is being chosen with its suitable capability. Bluetooth with globally available frequencies of 2400Hz can provide connectivity up to 100 meters at speed of up to 3Mbps depending on the Bluetooth device class. Bluetooth wireless connection enabled the system communicates with graphical interface (GUI) on Android smart phone without cable. The target home appliances are controlled by the system Main Control Board in order improve the standard of living reception, this system provides physical control method to the Main Control Board is performed as wireless remote control to the appliances. The Bluetooth wireless connection enabled the system communicates with graphical user interface (GUI) on Android smart phone without cable. The user can easily touch on the screen of the phone to control the home appliances. This portable method can assist the physically challenged people who have problem with locomotion difficulty.
