Development of a temperature detector and room capacity system to mitigate the spread of COVID-19

Abstract

Several efforts to mitigate the spread of COVID-19 and use a minimum of three layers of masks, it is also necessary to apply physical distancing in all work activities both indoors and outdoors. This study describes one of the efforts that researchers can do to prevent the spread of COVID-19, namely, designing a room capacity detection system equipped with a temperature detector. The research method is an experiment focusing on a temperature detector and room capacity system design. This system uses ultrasonic sensor HCSR04, temperature sensor MLX90614, PIR sensor (Passive Infra-Red) HCSR501, and infrared barrier sensor based on Arduino UNO to measure temperature and count the number of visitors in a room. The system designed based on Arduino UNO has worked well, where the system can detect the body temperature of building visitors and detect the number of visitors entering and leaving the building. The test results show that the temperature measurement on the forehead has a higher accuracy with an error of 1.17%. The results of this study will be used to design automatic door designs to mitigate the spread of Covid-19 in offices.
