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