BACKGROUND
•
•
•
According to the World Health Organization’s (WHO)
website under their health topics section on COVID-19, the
most common symptom of the corona virus is fever,
characterized by temperatures of 100.4° F (38° C) or
greater.
Also in our study of many health care facilities, we found
out that many doors in health centers are traditional with
handles and no sanitizing elements which pose a great risk
of infections, and at the entrances, health care providers
are used to measure the temperatures of the people
accessing the facilities to detect people with a fever, but
the process ends being hectic for the health care
providers.
So we came up with this project in which the door opens
automatically after measuring the person’s temperature
and the person is also sanitized automatically using the
sanitizing element at the entrance.
PROBLEM STATEMENT
Cross-Infections (CIs), also known as Hospital-Acquired
Infections, are those that a patient acquires from door
handles during his/her stay in a hospital or other door
handles. Such infections are Covid-19, Ebola, Marburg, and
Hepatitis B.
As a result, cross-infections increase patient care costs due
to the need for stronger and more expensive drugs,
contributing significantly to mortality, increasing hospital
lengths of stay and affecting the treatment of the original
medical condition.
Therefore we have come up with an auto door access
control with temperature and sanitizer parameters for
infection control.

centers, offices, and restaurants placed in indoor areas or
areas not exposed to direct sunlight. The components used
are Arduino Uno, Infrared Sensor, MLX90614 Temperature
Sensor, 16x2 LCD, Buzzer, Motor Driver, DC Motor, 7-12v
Adapter, and LED.

The study is limited to preventing the spread of infections
that are only transmitted through the touch of
contaminated surfaces.
•
Temperature sensor which can only measure the
temperature of certain body parts placed on the front of
the sensor
LITERATURE REVIEW
According to Saswat Kumar Das et.al, the goal of their
project was to make modifications to the garage door to
reduce human effort while the opening and closing were
also to increase the safety of the garage.
They were designing a door modification that could also
be applied to several doors that were sliding and rolling
in nature. For security purposes, they were considering
swiping a card or fingerprint scanning which makes their
project secure but a bit costly because these security
systems are pre-made and thus they are not cheap.
According to Christopher K.Prinus et.al, in their project,
they designed a low-cost automatic gate with a proper
security system. Their project aimed to show simply how
an automatic door works.

METHODOLOGY
BLOCK DIAGRAM
METHODOLOGY
Power supply.
This block supplies electrical energy to the microcontroller to
create signal impulses used to run the other block
components. This ranges from 7V to 12V DC power.
This power supply consists of a 9v power source that feeds the
microcontroller and the rest of the components through a 5v
regulator, as the power recommendations for the
microcontroller(1.8-5.5V). The capacitors are used to stabilize
voltage because of the distance of the microcontroller from
the source.
METHODOLOGY
The sensing block.
This contains the circuits for the temperature and ultrasonic
sensors. Temperature sensing is used to detect and read the
temperature of the incoming person. A mlx90614 temperature
sensor was use due to is high object temperature range(-70 to
380C).
BLOCK DIAGRAM:
METHODOLOY
• The temperature sensor converts the analog signals
into digital signals due the internal analog to digital
converter.
• In single PWM output mode the settings for PWM1
data only are used. The temperature reading can
be calculated from the signal timing as:
2𝑡2
𝑇𝑂𝑈𝑇 =
𝑥 𝑇0_𝑀𝐴𝑋 − 𝑇0_𝑀𝐼𝑁 + 𝑇0_𝑀𝐼𝑁
𝑇
METHODOLOGY
Body detection.
The sensing happens when the person is in the range that
the ultrasonic sensor was set to.
To generate the ultrasonic sound, you need to trigger the
trigger pin as high for a minimum of 10us, the module will
send 8 sonic burst ultrasound at 40KHz
METHODOLOGY
The values obtained from the resistors are such that:
Voltage(V) = 9v, current(I) = 50mA.
The resistance of the wires is R = V/I from Ohm’s Law
V = IR; therefore R = 9v/50mA = 180ohms.
The microcontroller.
This Arduino uno microcontroller creates multiple
signals to control the components for the door,
sanitizing, and sensing block. This is due to the program
input to it using C++ programming language.
LCD display shows the recordings of the approaching body
detected.
METHODOLOGY
Testing the prototype to see if it conforms to the set temperature
parameters. We made 5 trials recording the temperature at each
stage.
Results and Discussions
We made a housing for our prototype measuring 20*30*60 cm. The
power input to the system microcontroller is 9V.
In use, when the Infrared Sensor detects an object such as a human
hand, it will activate the MLX90614 Temperature Sensor. After that, the
MLX90614 Temperature Sensor will read how high the temperature of
the object is so that the results of these readings will be displayed on a
16x2 LCD screen.
When the temperature read is a normal temperature between 36 – 37
°C it will activate the DC Motor which has been fitted with gear to
rotate so that the door can open automatically and the LED will light
up for a few seconds as a sign of safety. When the recorded
temperature is not normal, the DC Motor will not be activated but the
Buzzer and LED will sound and flash several times within a few seconds
as a warning signal.
Conclusions and
Recommendations
•
The design of this prototype uses an Arduino microcontroller
using the C programming language. The accuracy of the
MLX90614 temperature sensor compared to a thermo-gun is
95%, so the sensor can be used as a body temperature
measuring device. The test results on the prototype prove
that all systems and components of the automatic door
control system with body temperature sensors can work with
a percentage level of 100%. Therefore, an automatic door
control system with a body temperature sensor can be
implemented in crowded areas such as shopping areas, and
offices.
•
The temperature sensor used is the MLX90614 temperature
sensor which can only measure the temperature of certain
body parts placed on the front of the sensor. It would be
better in the future to develop a measuring instrument using
a thermal camera.
•
Added database and mask detector when someone takes
body temperature. This is to make it easier to track the time
of finding people whose body temperature exceeds the
maximum limit when Covid-19 cases spread in the area.
