BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art. [0003] In the rise of pandemic situation, everyone needs to maintain self hygiene by taking necessary precautions, as transmission of a contagious disease can take place due to bacteria, virus, and other microorganisms thereby increasing health related risk and chance of infection for every sector including academia, industries, commercial institutions, etc. WHO has recommended the precautionary measures to follow self-hygiene and wear face mask in public places in order to prevent spread of the COVID-19. Therefore, wearing mask in public places is important and mandatory as per the government regulations which would help to prevent this diseases spreading from one person to another.
[0004] Wearing mask is necessary, when a person moves outside from his house, and compulsory at office, university, mall and any public gathering. However, many persons are still not wearing the mask while going outside from the home, and it they are having contagious disease that would be transfer to others. Also, when a person is having fever, he is not allowed to move outside from the house in this pandemic. Therefore, there is a need for a system which would ensure that the person is allowed to enter in the premises such as shopping complexes, offices universities, school, and other places only if wearing a mask and also body temperature of the person entering is measured to check fever, in order to prevent spread of COVID-19.

[0005] There is a need to overcome above mentioned problem of prior art by bringing a solution that recognize mask on face of the person along with temperature monitoring, and permits the person to enter in an premises. The solution is cost effective, easily installed, accessible and easy to operate.
