Low Cost Multipurpose UV-C Sterilizer box for protection against COVID’19

摘要

Ultra Violet radiation, Chlorination, washing with soap and heating are some methods of sterilizing. Ultra Violet light is the best sterilizing and disinfectant agent, used for domestic as well as clinical purpose. Food packets, books, stationery, medical equipments, toys, electronic gadgets like mobile phones, laptops, wrist watches, etc can be sterilized with UV radiation whereas other methods of sterilization cannot be used. UV light does not release any waste and is eco-friendly, if used in a controlled manner. UV radiation is a range of electromagnetic waves with shorter wavelength (high frequency and energy). The wavelength from 100-280 nm known as UV-C is the best disinfectant used for purifying water, air, sterilizing vegetables and surgical equipments. Research has shown that UV-C wavelength can kill harmful fungi, protozoa, bacteria and viruses like SARS-CoV-2 Virus. The article describes the construction of a low cost UV-C Sterilizer Box where UV radiation is taking place in a closed environment. Safety features are also incorporated to prevent humans from UV light exposure.
