Bluetooth Based Automation and Security SESTEM

Technology is a never ending process. In today’s life automation is important role in life. We all use mobile devices in our daily life. Because of this, home automation and security are becoming popular features on mobile devices. It also provides features like home security and emergency system. Home automation reduces human efforts and also increases efficiency and saves the energy. The main purpose of home automation and security project is to help handicapped, disabled and old people to control home appliances easily. We have designed a home automation and security system using Arduino UNO board. Home appliances are connected to the Arduino UNO with relay and they are controlled by using our mobile phones. The command is given by the android application from mobile phone which is connected to Bluetooth module. The Bluetooth module is interfaced with Arduino UNO board and the home appliances are connected to the input/output ports of this Arduino via relays. Since, Bluetooth communication is wireless, it is advantageous. For more security purpose we also can use password protection so that only authorized users can access the appliances.
