What is literature survey of project digital non-contact infrared thermometer with oximeter??? The idea of this project is to be able to read the temperature of every person who enters these public places. When the system is ready, the LED will light up, and when the temperature is too high, the buzzer will alarm and if the person’s temperature is high, the system will move to measure the heart rate and blood oxygen level then it will display on 16*2 LCD display
