Ultraviolet C, Sterilization, Arduino, MKR Wifi 1010Abstract
This study aims to determine the effectiveness of ultraviolet C light in sterilizing everyday objects. Arduino MKR WiFi 1010 is used as a processing device, UVGI lamp, 16×2 LCD, and a stepper motor controlled by the A4988 driver as an output device. Users can use this tool without direct touch because it uses an Infrared Proximity Sensor and an HC-SR04 Ultrasonic Sensor as input devices so that they can minimize the spread of microorganisms through physical contact with objects, especially during the current Covid-19 pandemic. In this study they used research and development methods. The data obtained in this study showed a reduction in the number of bacterial colonies that grew at each additional sterilization time, thus indicating that the effectiveness of ultraviolet C light sterilization was directly proportional to the length of time of sterilization.
