This paper presents a system that counts the number of people who enter a specific room after it has been screened for heat, heart rate, SpO2 and lights it appropriately. After a certain number of visitors have entered a room, the shutters will close. The visitor will be denied to enter the room if the visitor does not pass thermal, heart rate and SpO2 screening, but can be allowed through the telegram app if screening results just cross the threshold value.

Abstract. This paper presents a system that counts the number of people who enter a specific room after it has been screened for heat, heart rate, SpO2 and lights it appropriately. After a certain number of visitors have entered a room, the shutters will close. The visitor will be denied to enter the room if the visitor does not pass thermal, heart rate and SpO2 screening, but can be allowed through the telegram app if screening results just cross the threshold value. Telegram app can also be used to check the number of persons in the room and change the light color of the room. The RGB LED is switched ON, when somebody enters the room and the LED is switched OFF, when nobody is in the room automatically. The MLX90614 sensor is used for checking temperature, the MAX30102 sensor is used for checking heart rate and the SpO2 of visitors. A servo motor is used for controlling the shutter of the room. All the visitor's data and logs are saved on Google Sheets automatically for further analysis.
