IoT based microcontroller operated UV germicide system

With the rise of the COVID-19 pandemic across the globe, people have come to understand the requirement of sanitation. However, other than the personal hygiene, sanitization of all the appliances (like mobile phone, wristwatch, wallet, eye wear, etc.) has become very important. Therefore, the requirement of germicides is being increased to sanitize all the appliances. A few germicides comprise chemical sanitization mechanisms and others devices are based on high radiant UV (ultraviolet) light. From the available literature, UV-based germicides are more efficient and effective in killing the harmful microorganisms. However, in the existing system the rate of disinfection is less, which makes this system lag. In general, the UV-based germicides use UV rays for the sanitization process. The UV rays are one of the forms of electromagnetic radiation with the wave lengths from 10 to 400nm. Typically, there are three types of UV rays, viz., ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC) Moreover, UVA are longer waves, used as a black light through which microorganisms may be noticeable, while UVC are the shorter waves that kill the harmful microorganisms directly by destructing their DNA. Further, we have developed a germicidal system with greater rate of disinfection that is comparatively faster than the existing system, and it also includes the sanitization of our working environment too to disinfect the airborne organisms with greater accuracy. In the present invention, an IoT device that provides surface sanitization through microcontroller-based UV germicide is developed to reduce the disinfection time and air sterilization as well.
