Smart Digital Thermometer for Covid-19 Detection

During the COVID-19 epidemic, taking temperatures has been a major focus. The aim of this project is to implement a prototype of a cheap and high reliability digital temperature measurement device with the aid of Arduino Nano, Infrared temperature sensor (MXL90614), OLED 128 X 64 (0.96-inch screen size), IR sensor and buzzer. This thermometer uses an infrared sensor MXL90614 to detect the body temperature and then sends the reading to the microcontroller. If there is no human presence near the system, it will read zero; however, if there is, it will measure the temperature of the person through their hand or whichever portion is utilized as a point of contact closer to the system and communicate the reading. After that, the reading is presented on the OLED screen. The prototype's design and implementation were completed, and the desired outcome was obtained.
