COVID SAFETY SYSTEM – DOOR HANDLE SANITIZER & TEMPERATURE DETECTION

Abstract: Since December 2019 the world is under tremendous tension, the numbers are increasing day by day, and till date no vaccine has been full proved against the pandemic agent. The COVID-19 virus was unknown to us before it cast its outbreak in Wuhan, China. Being from a large family, a continuous mutation is occurring, forbidding the researchers, microbiologist, pharmaceuticals to search for the cure for the vaccine. Affecting the countries in a chain; China, Italy, Spain, USA, India , Russia, the virus has proved it’s strength and subservient a technologically enhanced race. The policies taken worldwide has lessen its affect to some extent but could not eradicate it. Lockdown has economically weaken many nations, and testing of different medicines has also not proven to be satisfactory. The design shows the preventive measure that can be taken during the COVID-19 pandemic in the whole world. Sanitizers have become the most significant commodities right now. By the new rules and regulations given by WHO vigorous sanitization is needed to survive. The design gave the solution for the problem stated. The design introduces an automatic hand sanitizer and temperature sensing system, to keep the hand sanitized whenever a person wants to do it, without a contact with the sanitizing machine. The temperature sensor on touching gives the body temperature of the person.
