Prototipe Kran Dan Sabun Pencuci Tangan Otomatis Portable Di Era Pandemi Covid-19

Abstract

An automatic hand washing machine is a tool that functions to clean hands automatically. This research aims to reduce the effects of the Covid 19 pandemic through Prototypes of Portable Automatic Faucets and Hand Washing Soap in the Covid-19 Pandemic Era. The advantage of this prototype is that it can work automatically when hands need to be cleaned and can be moved easily. This machine can release air and then release soapy liquid to help the hand washing process. Ultrasonic sensors on the air tap and soap liquid servo motor are used to detect the presence of hands that want to be cleaned. Air is released through a pump which is regulated by Arduino Uno as a microcontroller. Relays are used to control the input and output of this machine. The signal detected on the ultrasonic sensor is maintained as a relay input, then the relay transmits the signal so that air and liquid soap can come out automatically. The machine is equipped with a battery as an alternative power source. Using this tool can make it easier for people to clean their hands.
