Contactless Fog based Handwash Kit for COVID Safety

ABSTRACT

Recent days have changed tremendously, and rules are strictly being deployed to maintain social distancing, avoid crowding and frequent hand washing. Frequent washing of hands using our domestic water by a mass crowd result in water wastage which is a huge loss for our society. A better solution to sanitize the hands with reduced water wastage is attempted in this study. With technological advancements in engineering, several solutions and cope-up methods are being given to combat the spread of COVID-19 in this pandemic era. As an attempt, this study develops a Fog based Contactless Handwash kit which uses the Mis Spray method to sanitize the hands. The mist consists of water vapour and herbal sanitizer which is skin-friendly to humans. This kit is suggested to be deployed in public places to avoid the spreading of the virus since it is in a complete contactless manner. It is developed with an Atmega based microcontroller, NodeMCu,ultrasonic sensor and mist spray module economically. The outcomes of the developed handwash kit serve to optimally favour the preventing behaviour in this pandemic time. This study gives way for further research studies on the automatic sanitizing methods to combat the spread of the virus and its variants. © 2022 IEEE.
