Arduino based Touchless Temperature Sensing Visitor Notification System

The highly contagious COVID'19 virus's extensive distribution caused the pandemic, which intensified the importance of personal cleanliness and health. Wearing a protective face mask, keeping a certain physical distance, and regularly washing your hands with soap or hand sanitizer are a few precautions you may take to stay safe during this pandemic. An automatic touchless temperature-monitoring doorbell can provide guarded and touch-free temperature sensing, thus informing the household members. The widespread usage of outdated touch-type doorbells may result in the transmission of the coronavirus. The aforementioned article describes a novel approach to creating a Novel Doorbell system that can be activated using gestures and simultaneously detects the person's temperature and notifies the home of a suspected infectious disease.
