My idea was to build a smart ultrasonic diffuser that could be controlled via a mobile App. The diffuser had RGB LED lights and an ultrasonic atomiser, which could create a nice smell through essential oils. My mobile App allowed the user to set up the WiFi connection of the smart IoT device through the mobile app first and would then afterwards allow the diffuser to be controlled over the Internet through a cross-platform mobile app that was installed on a smartphone. In addition, there was a functionality to set operating schedules via the app, so that certain scents could be dispensed at different times of day, depending on the user's mood. In addition, I designed a 3D CAD model and branding, as I had originally planned to make this a commercial product.
