Mobile orientation based home automation for disabled and physically challenged

In this paper, we present a new way of controlling our home appliances by changing the orientation of the mobile phone. This solution helps the disabled and physically challenged people to easily control appliances without moving from one place to another. This method provides several advantages over traditional home automation interfaces. As the mobile phone consists of many built-in sensors like Proximity Sensor, Accelerometer, Gyroscope, etc. By this proposed method we can retrieve more from what the mobile phones are capable of. The values of change in perpendicular directions that is (x, y, z) are transmitted to the controller module (Arduino Nano) using Bluetooth Technology with the help of an android application. Particular symbol codes are programmed at the controller end to perform specific tasks.
