Automatic Boot Spray Machine: A Preventive Measure Against Corona Virus

Corona Virus (COVID-19) has already done havoc in the world. More than six hundred million people suffered from this virus and six million people are dead amongst them in the world. In Bangladesh, two million people have tested positive and approximately 30 thousand people are dead. SARS-CoV-2 virus causes this infectious corona disease. When an infected individual sneezes, coughs, speaks, or breathes, the virus is disseminated from their mouth or nose. One can also be infected by touching contaminated surface and spreads more in indoor environment. So, it has taught us the necessity of washing and sanitizing in our daily affairs. Automatic boot spray machine is a very practical and useful instrument to fight against the corona virus. This contact free spray machine helps to sanitize the boot without getting in contact with the surface and ultimately helps to prevent the spread of corona virus. The purpose of this essay is to create a boot sprayer that automatically releases soapy water. At a distance of meters, an obstruction sensor is employed to identify the heat and presence of the boot. A p-n-p transistor is used to operate the machine. This machine works perfectly at a distance of 2-30cm. It also provides good sensitivity percentage. This setup is user convenient and it saves money and power.

I. Introduction

The coronavirus family of viruses is very diverse. In Wuhan, China, the virus first surfaced on a limited scale in November 2019, followed by the first significant cluster in December 2019. [1]. The disease, which was caused by the Severe Acute Respiratory Syndrome Coronavirus-2 virus, was initially known as Coronavirus Disease (COVID-19) by the World Health Organization (WHO) (SARS-Cov-2) [2]. This virus, which is zoonotic (spread from animals to humans), was first discovered in bats [2]. Besides, this can be transmitted between human to human also. Direct touch, droplet contact, and airborne transmission are all ways that the COVID-19 virus can spread. A few recorded instances may have been spread by surfaces as well. According to laboratory tests, the virus may persist on various materials for differing lengths of time. Covid-19 can, in extreme instances, present as pneumonia. Acute respiratory distress syndrome can strike a patient for a brief period of time, leading to multiple organ failure and death [2]. Maintaining a distance of at least one meter, avoiding crowded areas, refraining from touching the eyes, mouth, or nose when outside, and washing hands with soap or an alcohol-based hand rub are all effective ways to prevent the spread of this virus [3]. A method of preventing Covid-19 is by providing containers for cleaning solutions in public areas, although this method is currently unsuccessful because there are portions that are frequently touched [2]. This may serve as the Covid-19 transmission point. Many health actions are carried out using automatic systems including air quality monitoring [3], hand sanitizers [4], [5] hand hygiene [6], [7].
