Overview
Application developed in the COVID-pandemic context CabAngels is a smart UV-C sterilization system designed for use in elevators (cabs). It utilizes UV-C light to effectively clean the air and get rid of any viruses (COVID-context) within the elevator cabin, reducing the spread of germs and viruses. It was a simple system, with 3 UV-C lights and 2 fans installed in a box above the ceiling of the elevator cabin. Air was recirculated through the box, sterilized with UV-C light, and blown back into the cabin. Light was never directly exposed to the cabin to avoid any harm to passengers. The reason for 3 lights and 2 fans was redundancy - in case one light or fan failed, the system could still operate effectively. It had a barometer sensor to detect when the elevator was in motion, and the system won't operate when the elevators are idle (UV-C lights didn't have a long lifespan) The system was equipped with Bluetooth Low Energy (BLE) connectivity, because the box is not easily accessible once installed, and technicians needed to check the status of the system remotely.
