Smart Thermostat<\/p>\n\n\n\n

\n

The “Smart Thermostat System with Configuration Management” project was developed as part of a Software Engineering course. The primary goal was to design a user-friendly smart thermostat system that enhances the overall user experience while providing efficient temperature control and scheduling capabilities.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

The user interface for the Smart Thermostat System was meticulously designed using Figma. This powerful design tool allowed me to create intuitive and user-friendly mockups, ensuring a seamless and efficient user experience. The use of Figma facilitated collaboration, prototyping, and iterative improvements based on user feedback.<\/p>\n<\/div>\n<\/div><\/div>\n\n\n\n

UML CASE DIAGRAM<\/strong><\/h2>\n\n\n\n

This design shows how a homeowner can use the thermostat. The thermostat can be controlled directly or via a phone app connected to a cloud network. It records temperatures for energy analysis, helping homeowners track usage. Changes to settings require PIN verification. The system settings backed up to the cloud and controlled the furnace, air conditioning, and fan.<\/p>\n<\/div>\n<\/div>\n\n\n\n

UML Sequence Diagram<\/h2>\n<\/div>\n\n\n\n
\n

A UML sequence diagram, also known as an event diagram, visualizes the flow of messages between classes. These diagrams are particularly effective for modelling run-time scenarios, helping developers validate their designs and identify interactions between classes that might otherwise be overlooked.<\/p>\n<\/div>\n<\/div>\n\n\n\n

\"\"<\/figure>\n\n\n\n

In this sequence diagram, I illustrated the following:<\/p>\n\n\n\n

    \n
  • Turn-On Response<\/strong>: The thermostat sends a turn-on response and requests PIN verification from the homeowner.<\/li>\n\n\n\n
  • PIN Verification<\/strong>: If the PIN is valid, the thermostat returns a “PIN OK” response; if not, it prompts the homeowner to try again.<\/li>\n\n\n\n
  • Heat Control<\/strong>: The thermostat can turn the heat on, interacting with the furnace. The furnace then updates the cloud settings to indicate it is on. If the furnace is off, the cloud can send a message to turn it on, and the furnace will notify the thermostat, which then informs the homeowner.<\/li>\n\n\n\n
  • AC Control<\/strong>: The same process applies to the air conditioning.<\/li>\n\n\n\n
  • System Settings<\/strong>: Changes to system settings can be made through the thermostat, which updates the cloud settings, and vice versa.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n\n\n\n

    UML Deployment Diagram<\/strong><\/h2>\n\n\n\n

    UML deployment diagrams help understand the relationships between hardware (nodes), software (components), and software products (artifacts). They show dependencies, interfaces, and nested nodes.<\/p>\n\n\n\n

    This diagram illustrates:<\/p>\n\n\n\n

      \n
    • Devices connected to the thermostat.<\/li>\n\n\n\n
    • Internal components of the thermostat.<\/li>\n\n\n\n
    • Connections to an external server.<\/li>\n\n\n\n
    • Deployment of the system with an executable file.<\/li>\n<\/ul>\n<\/div><\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n
