Abstract

As a precaution against the spread of the Covid-19 virus in public facilities, the
government requires to measure temperature and limit the number of people in order to prevent
new clusters, especially in crowded centers. To reduce this problem, a prototype of the number
of people entering and leaving through the IoT-based door will be made using an ultrasonic
sensor HCSR-04 equipped with a body temperature meter. This system works from reading the
temperature sensor value MLX90614, when the temperature is above 37oC then the door
remains closed and when the temperature is below 37oC the door will open, ultrasonic sensor 1
is placed on the entrance side and ultrasonic sensor 2 is placed on the exit side, if the sensor 1
receives one input, the system will automatically add a variable number of visitors, if sensor 2
receives one input, the system will automatically reduce the variable number of visitors, and
when the room is full of 10 people, the servo motor will close the door automatically, information
on body temperature and total person data will be displayed on the LCD and the Blynk
application and sent to the MySql webserver database in real time. The prototype system that
has been made is capable of detecting body temperature and counting the number of people
entering and leaving the door according to the design.
