Design of Automatic Door Lock Based on ATMEGA328P Microcontroller with MLX90614ESF DCI and HC-SR04 Sensors

In conditions like now, it is very important to check a person's health level to be able to enter a room so as not to transmit the disease that exists in that person. Infectious diseases can be avoided by keeping yourself healthy, besides taking care of yourself you can also avoid them by keeping your distance from people who are infected with infectious diseases. The purpose of this study was to keep someone from entering the room due to high body temperature. With MLX90614ESF DCI sensor that can measure temperature without touching and solenoid door lock to lock the door of the person is sick. The suitability of the temperature measurement carried out by this tool has been calibrated with a reference tool and the results of the coefficient of determination analysis are 99.80% of the temperature data obtained.
