Forgotten Item Detection System for Super First Class Suites

Project goal: To design a forgotten item detection system for the storage spaces in super first class airplane suites.When passengers forget to remove their belongings from the wide variety of storage compartments in super first class airplane suites, the result is cost and inconvenience for passengers and airline operators alike.The system is designed to detect items in six different compartments using a visible light detection system. Each compartment has LEDs and photo-transistors mounted on line replacement units that are integrated with an Arduino microprocessor and a display to notify when an item is detected. The optical and electrical performance of the components was analyzed to find the ideal number of LEDs and photo-transistors needed to detect an item left in any location, while minimizing the power drawn by the system. In addition, tests and inspections were performed to ensure system stability during in-flight and storage conditions.
