Design and implementation of IoT enabled ultraviolet C(UVC) irradiation-based sanitizer system for public transport with remote monitoring

ABSTRACT

During the ongoing Covid19 Pandemic, it is a need of the hour to have a fully sanitized public transport system, free from Covid19 virus. Public transport is one of the major segments responsible for the spreading of covid19 like pandemic infections. It is required to sanitize public transport before every new trip. During the Covid19 pandemic, human beings are forced to live with viruses, hence making disinfection a routine work and making disinfection more user-friendly and efficient is the main objective of this research work. Spraying alcohol-based solution inside public transport is not suitable due to fire safety and other reasons. Ultraviolet C (UVC) based disinfection is more suitable in such applications, as disinfection can be done anytime, anywhere without damaging the interiors of the vehicle. It can kill viruses or bacteria in less than 20 seconds and can disinfect any surfaces, seats, or any point of public contact inside any public transport by effectively killing bacteria, fungi, dust mites, viruses, etc. This research paper aims to offer the design and implementation of an Ultraviolet C irradiation-based sanitizer system for the public transport system, which can disinfect the public contact surfaces inside the public transport, to make our travel safe from Covid19 like viruses. The sanitization system is developed using a NODEMCU microcontroller, UVC led arrays, switching circuit, PIR sensor, and mobile app. Ultraviolet sensor is used to read UVC irradiation index inside the transport to measure the effectiveness of the developed system and real-time data is linked with internet cloud for remote monitoring and control. © 2022 IEEE.
