Automatic Boot Spray Machine: A Preventive Measure Against Corona Virus

ABSTRACT

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. © 2023 IEEE.
