Smart Door System to Prevent COVID-19 Transmission

The whole world has been witnessing a colossal adversary in the form of Coronavirus disease (COVID-19). With its super-fast spread, it has devastated a major part of the world and found to be the most dangerous virus of the 21st Century. Most of the countries went into lockdown to control the spread of the virus, and the economy shattered. Then slowly and gradually, some workspaces, malls, and public places started opening with the strict guidelines of governments. However, the fear of COVID-19 does not allow us to get back to our everyday lifestyle. Amongst the various symptoms observed in COVID-19-infected humans, the rise in body temperature is the most common symptom. As coronavirus is highly infectious, it is crucial to avoid physical contact with infected people to prevent the virus's spread. The primary reason for the spread of the virus is a lack of hygiene and a proper system to monitor the symptoms. Thus, the development of smart security systems for early symptom identification at the entrance of public places is essential to stop transmission. This paper covers designing a smart door system that measures the body temperature without human intervention and regulates people's entry through a mechanized door using Arduino UNO Board, IR thermometry temperature sensor, PIR sensor, and servo motor. The system will open the door only if the person seeking entry is normothermic, and if a person is hypothermic, it will trigger the alert system, which will eventually prevent the transmission of the virus.
