Abstract
The efforts to maintain indoor air quality from dangerous viruses need to be improved. One way is by sterilizing the room using a disinfectant which has a weakness, namely that it is unsafe if the disinfectant is exposed to the body, especially, when entering the respiratory system, it will become dangerous toxins. Therefore, an innovation of a healthy room that is safe for the respiratory system is needed by applying essential oil as a natural antiseptic liquid which is converted into gas through a diffuser that is connected to a gas sensor equipped with the Internet of Things (IoT) technology. It can record air quality data and connect to an Internet server to monitor indoor air quality easily and practically. The research was conducted by making different variations in the concentrations of essential oil to obtain maximum air quality. From the results we obtained, the level of air quality is getting better when the oil concentration is increased because more gas particles can bind contaminant molecules in the air.
