So in this Project, we are going to build an RFID based Contactless Temperature Monitoring System using a contactless temperature sensor with Arduino. When employees scan the RFID card, it will measure the body temperature of employees with a non-contact Infrared Thermometer and log the Name and Temperature of that employee directly to the excel sheet. We will be using Arduino Nano, MLX90614, EM18 RFID Reader, and Ultrasonic Sensor to build this project. The Ultrasonic sensor is used to calculate the distance between the thermometer and the person. The thermometer will only measure the temperature when the distance is less than 25 CM.

1) INTRODUCTION
Since the outbreak of the Covid-19 Pandemic, whole world has witnessed the worst
situations and people have faced and are still facing a number of problems in every field
as due to worldwide lockdown there has been a drastic fall in economies and loss of work
because of which financial and economical problems have become a major issue in this
pandemic period.
As the scientists and researchers are moving towards the development of the vaccine, till
then safety and following all the government rules and orders and following all the
precautions is necessary responsibility of all the citizens.
Since the outbreak of Covid-19, infrared thermometers are being used as a screening tool
to scan the people at Airports, Railway Stations, and other crowded establishments.
These scans are being used to identify potential patients of Covid-19. The government
made it compulsory to scan everyone before entering the office, school, or any other
crowded place.

3) BASICS OF RFID TECHNOLOGY
 WHAT IS RFID?
The Acronym RFID stands for Radio Frequency Identification , and refers to a technology that uses
radio waves to passively identify a tagged object. It is used in several commercial and industrial applications,
from tracking items along a supply chain to keeping track of items checked out of a library.
 Radio Frequency Identification (RFID) is a type of passive wireless technology that allows for tracking or
matching of an item or individual.
 The system has two basic parts: tags and readers. The reader gives off radio waves and gets signals back
from the RFID tag, while the tag uses radio waves to communicate its identity and other information.
 The technology has been approved since before the 1970s but has become much more prevalent in
recent years due to its usages in things like global supply chain management and pet microchipping.

 RFID Reader or Interrogator:
The RFID reader is like a transmitter which transmits or sends out
radio waves of particular frequency. If the object, on which this RFID tag is attached is within
the range of this radio waves then it sends the feedback back to this RFID reader. And based
on this feedback, RFID reader identifies the object.
 RFID Tags
(Three different kinds of RFID tags are commercially available.)
 Passive tags
 Active tags
 Semi-passive tags
These passive tags do not have any power supply. They used to get their power
from the incoming radio waves from the Readers. While active tags have a power source for
their internal circuitry. And for sending the response to the reader also, it uses its own power
supply. In the case of semi-passive tags, they have a power supply for internal circuitry, but for
sending the response it relies on the radio waves received from the Reader.

5) SOFTWARE REQUIRED
 Arduino IDE
The Arduino Integrated Development Environment (IDE) is a cross-
platform application (for Windows, macOS, Linux) that is written in functions
from C and C++.
It is used to write and upload programs to Arduino compatible boards, but also, with
the help of third-party cores, other vendor
development boards.

7) CIRCUIT CONSTRUCTION
As shown in the circuit diagram, the connections are very simple since we have used them as modules, we can directly build
them on a breadboard. The LED connected to the BUZ pin of the EM18 Reader module turns high when someone scans the tag.
The RFID module sends data to the controller in serial; hence the transmitter pin of the RFID module is connected to the
Receiver pin of Arduino.
