Abstract: In this Covid-19 Pandemic, whenever we go to any public places like Airports, Hospitals, Theaters,

Banks, Offices, Malls, Markets, sanitizing our hands is necessary. But most of us don’t sanitize our routine

accessories like Money, Smart phones, Watches, Masks which can also cause spreading of virus. So for

this purpose we are introducing our project UVC SANI-TECH. This project can be used at entrances of

public places. We usually sanitize our hands before entering any public place so at the same time by

placing our accessories in UV Box we can disinfect it in just 40 to 50 seconds.

Key words - UVC Light, Arduino, UV-C, UV-C Germicidal, UVC Sani-Tech.

I. INTRODUCTION

Not disinfecting our routine accessories when

we are at public place may increase the spreading of

virus. Our objective is to disinfect accessories from

all types of virus/bacteria using UV Rays in

minimum time without any harm. Ultraviolet Light

between 200nm to 280nm wavelength in EM

Spectrum known as Ultraviolet C (UV- C) Rays.

UV-C Rays of wavelength 222nm are suitable

enough to kill bacterias and viruses without

harming human skin, eyes or tissues. But we are

using UV-C Tube Light of wavelength 254nm

because 222nm UV-C Lights are not easily

available on local/online market for casual use.

254nm UV-C Tube Lights are usually used in water

filters [1].

II. INTRODUCTION ULTRAVIOLET RAYS

Ultraviolet light of wavelengths between 100

and 280nm is known as Ultraviolet-C light. These

rays effectively kills the virus that causes Covid-

19.Ultraviolet light is a type of electromagnetic

radiation and is responsible for summer tans. Too

much exposure to UV radiation is damaging to

living tissue.Ultraviolet light falls in the range of

the EM spectrum between visible light and X-

rays. One of the most common ways of producing

UV light is passing an electric current through

vaporized mercury or some other gas.

This type of lamp is commonly used in tanning

booths and for disinfecting surfaces. Light-emitting

diodes (leds), lasers and arc lamps are also available

Structure Explain:

Diamention of box is L=35cm, H=30cm,

W=25cm. Again Legnth 35cm is divided into 23cm

and 12cm. Structure of our project is like 3D

wooden box with door. On the right side we can see

input push buttons are there with LED Display.

UV-C Lights are connected in the box, we are

two UVC tube lights.We will stickAluminium foil

in internal side of box in order to ref

in all direction. Glass is attched to the door so we

can see if light is ON or OFF, UV Light will not

reflect through the glass as we are using UV

protected glass.

V. CIRCUIT DIAGRAM

Fig. 3 UVC Sani-Tech Circuit Diagram

Circuit Explain:

Arduino acts as a timer generator and it

provides the button input signal to the relay to turn

ON and OFF the UV lights. LCD is connected to

Arduino; it display the timer generated. Default

timer is of 40sec, when timer runs off at same time

lights will be OFF.Fig. 3 shows the circuit diagram

of our project. Arduino, LCD display, Relay,

Switch buttons, UV lights are the main components

of our project. Relay is important as it switches to

ON and OFF according to button input and controls

UV light. Buttons provide input to Arduino to turn

ON and OFF the lights. Buzzer is indicator of

Timer end. UV lights will require AC 230v mains

and Arduino required DC power of 5V.

VI. RESULT

Before UVC Rays After UVC RaysFig. 4 UVC Light Indicator Output

Result Explain:

In the Fig. 4 we can see a UVC indicator

card which changes its yellow color into the given

range of orange colors. Four orange color ranges

are there 50mJ/cm

100mJ/cm2,150mJ/cm

2,200mJ/cm

2, which indicates

the power of UVC Light.

Observation:

1st image showing UVC indicator card

before UVC rays, we can see the round yellow

portio is yellow and matches with the initial color

portion. Now in the 2nd

image we can see the color

of the yellow portion is changed into orange color

shade which is similar to 50mJ/cm2.

For how much time we kept card under uvc light?

This depends on factors hight and time. We putted

the card in box having 35cm hight and for 18 hours.

Time for putting card under uv light changes

according to hight of light. Result shoul

checked within 24 hours.

VII. ADVANTAGES

− UV-C Light rays can kill all types of

germs/bacterias/viruses.

− In UV SANI-TECH you can clean

accessory of any size & colour (bags/purse

etc.) in minimum time.

− For safety reasons UV-C Light will turn ON

only when box door is closed.

VIII. DISADVANTAGES

− The UV-C Light we are using in project

have wavelength 254nm which is mostly

used in water cleaning process; these lights

are more effective in water.

− Direct exposition of human tissues, eyes,

skin in UV-C light is harmful.

IX. FUTURE SCOPE

Presently, We can use this project at public

place entrances with precautions and safety

instructions.We are using UV Rays of 254nm

wavelength in project because these UV lights are

available at markets with affordable price. But these

UV rays of 254nm wavelength are harmful to

human tissues, skin, and eyes so by taking

precautions and alertness we are building this

project. In future upgradation we can use UV

Light wavelength of 222nm which is not harmful to

humans but it can effectively kill germs. So that we

can use this project even for domestic purpose.

222nm wavelength UV Light is not easily available

in local/online market for project use.

X. CONCLUSION

We are pleasure to conc

the topic “UV SANI-TECH”. The detail of this

project has been made by members of our team

sincerely with the inspiration of our tutors.Through

this project we have done disinfection of

accessories using UV-C tube lights. For controlling

counter of 40-50sec arduino, LCD, relay is used.

Fingerprint scanner is used for

purpose. The result we are getting from that we can

conclude our project is enough to kill germs present

on objects/accessories in 40 to 50 sec and our UV

rays tube lights are working fine.
