Development of a Portable Hand Sanitizer based on Arduino

Abstract

In the ongoing era of the COVID-19 endemic, hygiene is an important aspect that needs to be emphasized. Hand sanitization is one of the most effective tools in preventing the transmission of microorganisms, which are the cause of diseases. This created portable hand sanitization project aims to provide an alternative that is more effective and practical than manually used soap. The project is equipped with an ultrasonic sensor and an Arduino UNO microcontroller to detect hand movements and automatically dispense a sanitizing spray. This makes it user-friendly and easy to use. The advantage of this project is that it does not require hand contact and is suitable for everyone, especially individuals with disabilities and children. Additionally, with its attractive design, this project is seen to be able to attract users' interest, especially among students. The development of this project is seen as a significant contribution to the efforts to combat the spread of contagious diseases and prevent the continuous transmission of COVID-19.
