IOT Based secured Low-cost Visitor Tracker using smart Application

Abstract

Since the end of 2019, the world has been reeling with the COVID-19 pandemic. The drastic and dramatic spread has affected human lives and livelihoods as well as businesses across the world. Organizations across the world are uniting and coming forward to minimize the seriousness of healthcare. The survival of the human community should be the top priority during this time. To control spread, respective higher authorities impose restrictions on public gatherings, with strict action taken against those who exceed the maximum allowed people in public gatherings. Our IOT-based project aims to limit the number of people entering the academic blocks during COVID-19 in order to monitor overcrowding in these buildings. Our electrical circuit or device will monitor the number of people entering the academic blocks, and once the maximum allowed number of people is reached, the next person will not be allowed to enter the building, and the electrical circuit will ring a siren. This will also ensure that social distancing is maintained. Our project is based on Arduino. Several electrical components, such as an Arduino Uno, a prototype, a breadboard, a piezo-buzzer, ultraviolet sensors, and jumper wires, were used. Software simulations were carried out in the well-known online electrical circuit compiler, Tinkercad. A hardware simulation of our project was also made.
