Application of Temperature Measurenment Contactless with Bidirectional Visitor Counter Using IoT as a Covid-19 Protocol

Abstract

—Adaptation due to the Covid-19 pandemic has changed the order of life. When activities begin to move again, at the same time we must remain vigilant so that the spread of the virus can be suppressed. One that can realize health protocols in public places and facilities is the engineering process, such as by providing a visitor counting system accompanied by recording body temperature as screening and being able to restrict access as a form of implementing health protocols. The system is also expected to facilitate security officers in the process of optimally implementing health protocols. The system built consists of hardware temperature sensor MLX90614 with an accuracy value of 99.50%, TOF and IR sensors to count visitors in two directions, Node MCU ESP32 as the main controller and website as information media that shows the temperature of visitors, number of visitors, number of outbound visitors, and available places. This system is also equipped with an SD card facility so that it can simplify the process of screening and recording visitors every day. This system is practical because it can be implemented on a one-door system which is usually used as an entrance and exit door at the same time.
