Abstract
The novel coronavirus disease (COVID-19) has already affected over 6.9 million people, claiming more than 400 000 lives in over 200 nations all over the world. In this paper an embedded system with MQ sensor for breath based covid19 detection. RFID tag present in the embedded which holds the location of the specific shop. When a person enters the shop has a portable device in which an RFID reader is present, so while entering RFID reader reads the geographical coordinates present in the shop’s RFID tag and stores in into the node MCU present in the portable device this process is used in tracking the individual in case if person is tested COVID-positive. While leaving the shop QR code scanning takes place. The portable device generates a QR code that holds the identification of the person who is using the portable device. The embedded system which is present in the shop has a QR code scanner and a PC that examines and stores the information, this process used for tracking a whole community of people. MQ sensor is interfaced with the node MCU on the wearable device. This module is used for personal detection of covid19 this information can be conveyed with the help of two LEDs one red and one green. Green LED indicates a covid19 free person and red indicates an infected person for shops safety. All this information can be stored for future analysis. With help of the proposed system government can able to easily track the patient if patient is affected by COVID-19. Since the device is portable it can be used by everyone without age restriction.
