The cost of electricity in 2015 pledged 11.83% of the budget, equivalent to R $ 201 758.40 of the IFMA São João dos Patos budget was R $ 847.51 Order 2611. Make efficient monitoring of these costs can result in significant savings in power consumption and cost containment. The starting point for the development of the project was the self cost of electricity bills on campus, caused by energetic waste, the main factor inappropriate use of air conditioners as these that there remain on unnecessarily contributing to increasing the power consumption and, consequently, the increase in power account value. There is no way to know which units are in use or information with respect to room temperature. Another factor that contributes to the worsening of this problem is the length of lighted lamps when not going pedagogical activity in that environment. This is due to the campus to have a single server to perform the function on / off these devices. The focus of this work is the development and implementation of a low-cost automation center, from the interaction between an Arduino Uno board and an ethernet shield controlled remotely via the Internet. Therefore, an application was developed for mobile devices (mobile, tablet) that use the Android operating system to control all functions of the air conditioners of São João dos Patos IFMA. The application chosen to develop the App was TouchOSC that uses the TCP / IP protocol to send and receive information between the Arduino and the mobile device. Another reason for the choice of this App was the fact that it features a friendly graphical user interface and does not require knowledge of Java programming to develop the application. Messages will be sent via wi-fi allowing the activation of conditioned air from anywhere in the world communication. For application development was used the Processing and C ++ languages.
