Home Automation

[Add figure form the proposal]

The above schematic represents the complete model of our designed product: Smart Home Automation System.

 

As seen in the above schematic, the user interacts with the microcontroller through a Smart Phone App. Now, depending on the function that the user wants to carry out, the system uses two different processes or pathways to complete the users’ request. To simplify this process, the system is further subdivided into two modules. Module 1, as seen in the above diagram is the light control system. The microcontroller that is used to control the functioning of module 1 – light controller is an Arduino Uno with a WiFi Shield. This is due to the fact that the entire light control module was designed using Uno rather than the Yun. The function that is used to control the brightness is native to Uno and cannot be borrowed to the Yun. Thus, the user selects a brightness level using TouchOSC. This information is passed on to Arduino Uno microcontroller through the Arduino Yun microcontroller. A server is used to connect the two different Arduino Uno and Arduino Yun microcontrollers. Once the request from the user is sent to the Arduino Uno microcontroller through a server, input readings from the light sensor is used to increase or decrease the brightness of lights in a room.
