• Built-In Assistant: Get real-time alerts for potential hazards such as gas leaks, fires, and unauthorized access, ensuring your home stays safe and secure.

• Emphasize the User Experience: This system combines practicality and convenience, ensuring users have complete control over their home environment from one centralized location.

⚒️ Technology Stack

Software

• The Interactive 3D Virtual Home was developed using Unity3D.
• The 3D objects and other assets used to built the 3D Virtual Home were created using Blender.
• Firebase was used as the database and Single Source of truth for the state of the different Electronic Components.
• The User Interface and Arduino Board was programmed using C# and C++ respectively.

Hardware

• An Arduino Uno Board is used to control the appliances by receiving commands from the NodeMCU Board. While the NodeMCU can also control appliances, the Arduino Uno was preferred due to its higher number of digital and analog pins, and its ability to support up to 12V
• A NodeMCU Board which acts as a bridge between the software and hardware. It directs the Arduino UNO Board to control the appliances by listening to the app.
• Relay Switches to switch on/off the appliances electrically and protect the system from too high voltage or current.
• Gas Sensor to detect smoke and trigger sound.
