Abstract

A virus is a microorganism that causes infectious diseases. One of the pandemics in Indonesia in 2021 is caused by a virus named SARS-CoV-2. Both the physical and mental health until the national economy are disturbed by the COVID-19 pandemic. The use of ultraviolet light is intended for killing viruses around us. There are several kinds of ultraviolet light, such as Ultraviolet A (UVA), Ultraviolet B (UVB), and Ultraviolet C (UVC). The wavelength produced by UVC light is 253.7 nm. The wavelength is effective in killing viruses and bacteria. However, UVC light is not safe for humans, especially human skins. A controller system for UVC light is made so it can be safe to be used by humans. The controller system is connected to the internet to control UVC light anywhere and anytime where internet connection is available. This controller system consists of NodeMCU ESP8266 Amica as the processor module and a four-channel Relay Module put together inside a box made from acrylic with dimensions of 9.5 cm × 9 cm × 5 cm. The acrylic box is placed in the room within the Wi-Fi range. The controller system could be accessed by an Android smartphone that has the controller application installed in it. The application in the Android smartphone is designed by MIT App Inventor, which is also connected to Google Firebase. A controller system can control up to four UVC lights for sterilization purposes in some rooms. Controlling UVC lights can be done because of the connection between the application on Android smartphone with real-time database on Google Firebase and the processor module. Keywords: Virus, ultraviolet C, controller, real-time database, Android, NodeMCU.
