Clear hands, Clear conscience: Fog disinfection, dry hand washing

Abstract

Proposing a water-saving hand washing solution, we introduce a system designed to reduce water usage by over 95%. Highlighting the importance of hand hygiene in combating pandemics, we challenge the notion of excessive water requirement for effective disinfection. Our system, controlled by an Arduino microcontroller, incorporates ultrasonic sensors, mist maker, UV lamp, and timer buttons. It activates mist and UV components based on user-selected time, ensuring efficient disinfection. Alerts are issued if hands are prematurely removed, enhancing hygiene without water wastage
