  • Abstract

Every time someone wants to enter a traditional door, they usually have to open it by hand. As a result of the current COVID-19 pandemic situation, it is imperative that every human being take precautions such as wearing a mask, maintaining a distance, sanitising their hands and arms, and not touching anything excessive. A prototype of an automatic door control system with a body temperature sensor is designed to limit direct physical contact with conventional door knobs, preventing the spread of COVID-19. The main motto of this project is to utilise a sensor with a combination of embedded equipment for the door opening system. The components MLX90614 Temperature Sensor, Passive Infrared Sensor, Arduino Uno, 16 × 2 Liquid Crystal Display, Servo Motor, and Light Emitting Diodes are used to implement the system. The door gets opened when any human movement is detected near the door, as well as when it detects its temperature and the presence of a mask with the help of various tools and technologies. A passive infrared sensor observes the motion and transmits a signal to the transistor, which in turn gives an interrupt signal to the programmable ATMEGA microcontroller. A contactless infrared digital temperature sensor then senses the body temperature of the human, and if the temperature is above the brink temperature, the output signal is transmitted to the direct current motor that's used to unlock the door and to the Arduino. This is a prototype where all these electronics are plugged together to get the corresponding output
