ADX: IOT-Based Integrated Smart Control System for Prevention of Airborne COVID-19 Spread

Enclosed spaces are places with a higher potential for spreading the COVID-19 virus. This is because the COVID-19 virus can be carried in the air. Closed space makes the air last longer in the space. Moreover, closed spaces are widely used, such as homes, schools, malls, offices, places of worship, etc. So for closed spaces, serious attention must be given to avoid the spread of the virus. ADX is an IoT-based tool equipped with UVC rays that can kill viruses, including the COVID-19 virus. This tool can be controlled remotely, manually, or on a timer. So that the device can be activated first before the closed space is used. This study also used the ESP8266 microcontroller in supporting the development of IoT-based ADX tools. The results of this study with an accuracy of the IoT ADX system of 96.10% and the average response time is 1.47 seconds.
