Abstract
The design of the sterilization box is based on the ATmega2560 microcontroller which utilizes the concept of 254 nanometer UV-C shortwave radiation and disinfectant spray to increase the effectiveness of the sterilization box. In order to prevent transmission through touch from users through physical contact via sterilization box, researchers designed a system that can make users access sterilization box without the need to make physical contact with the device, namely by using IoT system with the help of applications that can be accessed through the user's smart device. Based on the results of the analysis and experiment that has been carried out, it is concluded that the sterilization box in this study can work optimally at a distance of less than 700 cm. This tool can operate using smartphone media via bluetooth HC-05 module, so it can minimize the process of spreading Covid-19 that occurs through physical contact.
Highlights
In the new normal era, people are still facing the shadow of the Covid-19 virus, plus the number of people exposed is still increasing to this day
Transmission from direct contact can be in the form of touching the patient or it can be from objects exposed to the Covid-19 virus
The Covid-19 inactivation media will use short-wave UV-C light with a wavelength of 254 nanometers and a disinfectant spraying device to sterilize tools suspected of being exposed to pathogens
Summary
In the new normal era, people are still facing the shadow of the Covid-19 virus, plus the number of people exposed is still increasing to this day. Transmission from direct contact can be in the form of touching the patient or it can be from objects exposed to the Covid-19 virus. The Covid-19 inactivation media will use short-wave UV-C light with a wavelength of 254 nanometers and a disinfectant spraying device to sterilize tools suspected of being exposed to pathogens. The use of UV-C sterilization is not limited to the Covid-19 virus, but can be applied to sterilize medical surgical instruments, baby equipment, work equipment and others. This tool is designed using a Smartphone application using the Bluetooth module (HC-05) as a liaison between the smartphone application and Arduino
