APPLIFI APPLIANCES CONTROLLED USING WIFI

This paper presents the most economical and flexible solution to control and operate home appliances using Smart Plug devices. The Smart Plug is a power switch which functions via Wi-Fi connection. It consists a current sensor, two temperature sensors and an IR emitter. Users can plug devices into the Smart Plug to remotely switch power on/off, get information of device's power consumption and ambient temperature, and simultaneouslycontrol the nearby devices using the integrated IR-emitter. There are two ways to access Smart Plug that is, either connecting it directly in Wi-Fi AdHoc mode or connecting it with a router in WiFi infrastructure mode and accessing online with IPconnectivity. The paper utilizes Restful based Web services in which the overall system architecture is Client/server model and the Web client use JavaScript and Ajax to transfer data. An Android-based Smartphone application employs standard operations such as Get and Post requests that return responses to communicate between the remote user and the Web server. It depends on the user how to use the smart plug, they can use smart plug as lighting switch, timing switch, infrared controller and temp regulator.
