Making of An Automatic Liquid Soap and Water Dispenser with Integrated Automatic Hand Dryer
Abstract
Rapid spreading of bacterias and bacterial diseases is a sole effect of poor hygiene facilities. The
conventional hygiene system that is being following is also a major cause of spread of bacteria. Since
the coronavirus broke out and spread over the world, demand for hand sanitizers has skyrocketed.
Hand sanitizers are often applied by pressing a pump with one's hand to squirt the sanitizer liquid. As
a result, a large number of people come into touch with the pump handle, increasing the danger of
viral transmission. On the market, several hand sanitizers are automatically pumped. However,
because hand sanitizer containers and pump mechanisms are only designed to work with other
products from the same manufacturer, consumers must also replace the liquid container if they
replace the hand sanitizer. As a result, this study proposes the development of an automatic hand
sanitizer system that can work with a variety of sanitizer containers. The need for this concept was
inspired by an unhealthy pattern of hand washing and drying in numerous restaurants and food-
selling establishments. Automatic soap and water dispenser integrated with automatic hand dryer
makes use of recent automation technology to improve hygiene facilities at its best. It makes use of
Arduino- an open source electronic platform which can be programmed to automate the conventional
hand washing and drying actions. This type of automation is achieved with the help of ultrasonic
sensors which perceive the position of hands as input and interact with Arduino so as to take up the
desired actions. The ultrasonic sensor transmits the ultrasonic waves continuously once it is setup
HIGH and the receiver aside it receives the same signal once it is interrupted by hands. This received
signal acts as input to Arduino and provides the output for a desired time as specified in delay
program. This automation technology eliminates the hand interruption, which is likely to spread
bacterias, thus making process simple and clean.
