Automatic Dry Hand Sanitizing Device

Abstract

Abstract: The world faced so many problems during the Covid-19 pandemic. Washing our hands was an integral part of preventive measures of the Covid-19. But it is found that it wastes so much water in the world. Many people do not have access to clean drinking water and face water scarcity. The sanitizer is also used by many people. But excessive use of sanitizer with high alcohol concentration leads to dry, itchy skin. The indirect consumption of sanitizer through the hands leads to the risk of other health conditions. In this proposed system, fog making technology is used for dispensing sanitizer. So that only the required quantity of sanitizer is dispensed and it covers the entire surface area of hands, guaranteeing the disinfection of hands. This system is proposed to reduce water usage by around 90%. It also saves 20-30% of the water that rolls over the hands while washing the hands and also the water required for washing hands. This system did not completely replace the handwashing method but it helped in saving a remarkable quantity of water. It also helped in preventing skin diseases and other potential health hazards.
