Design and implementation of a smart automatic door opening system to detect high body temperature and provide covid-19 disinfection

Abstract

One of the measures to decrease the transmission of coronavirus ailment 19 (Covid-19) is to take your body temperature and disinfect it.     Measurement of body temperature is done as an attempt to identify people with Covid-19, so it is necessary to prevent them from coming into contact with others.     Manual temperature measurement can lead to burnout for personnel performing the task and reduced accuracy. Therefore, it is necessary to build an automatic temperature measurement system and display the data easily.   In addition to measuring your body temperature, another step to prevent the spread of Covid-19 is disinfecting your hands.    The disinfection process can be carried out by spraying disinfectant gel automatically on your hands.     These two processes are carried out sequentially, after measuring the body temperature and not exceeding the allowable limit, followed by the disinfection process.  This method is implemented on a gate equipped with two leaves, with the first opening of the leaf occurring at a body temperature not exceeding the permissible limit, and the second opening of the leaf occurring after automatic disinfection of the hands.To minimize physical contact, the process is automated and contactless. To develop the system, one Arduino Mega 2560 microcontroller, 3 MLX90614 sensors, 3 HC-SR04 sensors, 3 e18-d80nk sensors, 1 relay, 1 DC pump motor and 2 DC blade drive motors are required.  The body temperature limit can be set manually.     Operationally, the system was tested and demonstrated to work, including spraying disinfectant gels.    To check the temperature measurement, there was an average deviation of 0.018% from the sensor measurement for the temperature measured with a heat gun.
