Abstract: COVID-19 is a disease caused by the SARS-CoV-2 virus that primarily attacks a person's respiratory system. Some milder symptoms can include fever, aches, and chills, but it can also lead to more serious conditions such as pneumonia. A person who has pneumonia or even slight shortness of breath might not know when to go to a hospital, especially as they start to get even more overwhelmed.We have developed a system where we can check thermal temperature and oxygen level in the body of a person, so that they can be warned if they are going through any of the symptoms.This system will use mlx90614 sensor to record thermal temperature of the person and max30102 sensor for recording oxygen level of the body. To use mlx90614 with accuracy we placed an ultrasonic sensor, so that when the person is in accurate range of mlx90614, the sensor will read temperature. And if the body temperature is above 37 degree Celsius then it will blow a buzzer and if the oxygen level (SpO2) is below 90 then also it will blow buzzer and also when both temperature and oxygen level are not in under respective threshold the alarm will blow.The controller we are using is Arduino Uno and Software we are using is Arduino IDE. We are also using a pressure pump and nozzle to create mist of sanitization liquid. To detect a person’s hand under sanitizing mist we are using another ultrasonic sensor. Our system is capable to sense and display the thermal temperature reading of the body as well as the SpO2 level of the body. So when a person comes to the system he will have to place his hand near the mlx90614 sensor, then the ultrasonic will detectthe person is in precise range of the sensor and record the temperature of the person. If the temperature is less than 37 degree Celsius then it will blow the buzzer once indicating it is safe and if it is more than 37 degree Celsius then it will continuously blow the buzzer with 1 second interval for 10 times indicating that the person is not safe and should contact hospital as soon as possible. Similarly for oxygen level (SpO2) below 90% it will indicate blow the buzzer indicating the person is having strong symptoms and should contact hospital immediately. So by using our system we can ensure a safe environment in offices and institutes.Keyword: Arduino, Spo2, Covid-19
