Abstract :
The emergence of the COVID-19 virus makes people around the world have
to live a new lifestyle to avoid being exposed to the virus by implementing health
protocols such as wearing a mask, checking body temperature, and spraying
disinfectant. However after doing it all COVID-19 transmission is still big in
crowded locations so it is necessary to limit visitors to avoid crowds in order to
reduce the number of virus spread. In this research designing a visitor management
system with an automatic hand sanitizer based on the Internet of Things using
Arduino. The advantage of this system is that the automatic hand sanitizer will be
installed on two doors entry and exit which can simultaneously limit the number of
visitors who will be monitored through the IoT platform application. This system is
designed with Arduino Uno R3 components as microcontrollers, ultrasonic sensors
that will be installed in two door locations in and out with an automatic hand
sanitizer. For remote monitoring using the IoT platform application with the
ESP8266 ESP-01 wifi module as a link. From the test results the proper hand
distance when using the hand sanitizer is from 3 cm to 9 cm and the proper volume
of hand sanitizer is approximately 1 ml for a duration of 250 milliseconds. The
process of uploading data from the system to the webserver takes about 9.7 seconds
to 16.17 seconds.
