SMART IOT TECHNOLOGIES FOR COMBATING COVID-19 PANDEMIC: AUTOMATED TOUCHLESS HAND SANITIZER DISPENSING SYSTEM

摘要

There's a wide health emergency bartering the world with the rising and diffusion of 2019 novel coronavirus (2019-nCoV) or what is known by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It has diffused across the world and affected many people. In addition to the absence of efficient treatment and vaccination, the COVID19 currently represents huge environmental resistance. The direct contact between person and person is speeding up the easy spread of such disease. The droplets involved in coughing and sneezing promotes the early infection by virus. The droplet has ability to survive in air and even on the inanimate surfaces and diffuse the infection to the individuals. So as to minimize the virus spreading, it is better to limit and restrict the constant contact among the individuals and those who are possible carriers of virus. In the present cases, the continuous disinfection of general zones and social distancing play a crucial necessity. In spite of currently sanitizing of hands is essential activity, the infection may be increased due to touching of bottle surface utilized by infected person. Therefore, proper evaluation of effectiveness for the disinfections is a critical matter. This study aims to propose a system design of hand sanitizer that is contactless and based on IoT robotics technology. Further, the developed system is capable to disinfect the hands with minimum time and human involvement.
