DEVELOPMENT OF WI-FI-BASED SWITCH CONTROL SYSTEM FOR HOME APPLIANCES USING ANDROID PHONE

This study aims to develop and design a prototype that can be used, together with an android phone as centralized switch for simple home appliances via Local Area Network or Internet. The prototype can handle up to seven devices at the same time with a master switch. The main body of the prototype contains an Arduino microcontroller connected to a relay driver circuit. An android application is also developed using Basic4Android IDE. The proponents add features such as renaming devices and password security to make a user-friendly interface. The proponents used the developmental method and conducted several tests to determine if the prototype satisfied the scope and limitations. The proponents tested the prototype to handle varying number of output devices from two to seven loads and showed that the prototype can really automate the switching of simple home appliances and therefore can further develop for a full home automation system.
