This project is based on the construction of a model simulating a home automation with different operation modes which can be controlled also by a mobile application. To achieve this objective, a scale house that captures different signals, both digital and analog, has been developed. To approach the house to a real home automation application the variables under study and control are interior temperature and lighting, movement around the house and water level of the pool. The house has three main operating modes. In automatic mode, it performs the measurement and executes the control of the variables, regulating itself according to the conditions to which it is exposed. In contrast, the remote mode is achieved using the mobile application that allows user to modify the variables. Finally, in alarm mode it controls the parameters that assure the security of the house when proprietor is away from home. To capture the signals, the prototype has temperature, lighting, movement and water level sensors installed, and for the regulation and control it has a fan, some LED, an acoustic warning device and a water pump. The core is an Arduino Mega board that allows the application operation and receives, from an Android mobile application, operating modes commands and, if it is operating remotely, orders to individually control the different actuators. For the data transmission from the mobile to the board, is used communication via Bluetooth.
