IOT based corona preventive polycoat with automatic sanitization system

Nowadays, due to the pandemic situation people are stressful. They are fighting against this virus by launching various preventive measures such as “PPE kit”, “Sanitizer Machine”, “ELISA test”, etc. with the help of which India recovered 54% from this virus. At the mean time all the workers are highly at risk for the huge amount of economic loss. Focusing on their situation, a new kit model will be generated in India. To bulwark from COVID-19, preventive measures are employed, which is developed cost-effective and medicated fabric-based full body-cover protective sanitizer polycot. In this research paper, we have proposed an IOT based sanitizer polycot in which Sanitizer Fogging Machine using timer will be fixed. As laminated polyester non-woven fabric with polycot found as the material to get the best product, so the sanitize machine will be automatically connected to the polycot. At the mean time timer will help to sanitize it for particular time. So, that the solution does not get wasted. This will not only help the doctors, nurses to protect themselves but also everyone can use it. It can be easily affordable and also hygienic to use.


Introduction
IOT based sanitizer polycot is used to protect everyone and fight against  In the year 2020, India's first PPE Kit Seam Sealing Machine was launched in Rajkot, who not even manufactured a single PPE kit, has now producing around 2.06 lakh PPE kit per day. The world's 2 nd largest PPE kit producer in just 2 months after China is India, who is also developing the world's first reusable PPE suit. India is a very well-known country experts in launching new products, but it hardly launched a kit based on automatic sanitization. The basic advantages of automatic sanitization suit are: -The automatic sanitization of suit will prevent from spreading the virus as in such system people do not have to sanitize manually, they will get automatically sanitize through fogging machine. -The automatic sanitization will not waste the sanitizer too much as a timer will be fixed in the suit, so that it will sanitize for a particular time only.
Why Automatic Sanitization? In the present situation, it is not always possible to sanitize our body after touching every object or clothes and it is not even possible to remember. So, to reduce the problem at some extent protect yourself with "Self-Sanitizing Suit". A suit that will sanitize itself at regular intervals to avoid the spread of coronavirus through our clothes. The suit will be connected to a timer at which the sanitization liquid will flow. Since the product will be in high demand during this condition, we put an effort to reduce the cost of so that everyone can afford to use for their safety. PPE refers to protective clothing, face shield, head-cover to protect the human body from virus and infection. It is light in weight and has excellent water absorption capacity which is free from chemical agents and is also comfortable and safe to wear.

Hose Pipe.
A hose pipe is a hollow tube which is flexible and carry water from one end to the other. It is used for spraying the sanitization liquid to the full body as the shape of a pipe is usually cylindrical. It is fitted between the two layers of the suit to flow the fluid solution.

Misting Nozzle Tee.
A nozzle tee fits pipe and used for flowing of fluid. This tee is used for fixing the nozzle spray in the hose pipe. It helps to connect the nozzle spray and the pipe together to flow the fluid.

Nozzle Spray.
A nozzle spray is a device used to flow the fluid in the form of spray. With this system the polycot will be sanitized, which will be placed between the two layers of the polycot. This product range consists of 10-1000 of nozzle design forms. The increase in the fluid pressure, increases the flow through the nozzle, and decreases the drop size.

Arduino Nano.
A board which is microcontroller formed on the ATmega328P. It depends on both input and output pin. This board is also available for reading the finger inputs on a switch and to activate the motor it turns into output. 2.1.6.LCD Display. The light-modulating quality of liquid crystals is used in an optical device which has LED backlight with yellow-green features and commonly used interface is HD44780. This interconnection found on most parallel character displays and operates without a backlight. It executes an area with large view in a small package.

Membrane Switch Keypad Arduino.
A membrane keypad allows to interact with a microcontroller, consists of rows and columns in a matrix. Each and every key is set to one row and column. On a keypad there are 12-button having 4 rows and 3 columns.

2.1.8.DC Submersible Motor.
A brushless motor which is long lasting. Submersible pump is placed within the solution of water that needs for flow out the solution. This type of pump runs on a motor which operates on direct current. Therefore, no battery is needed. It can work continuously for a longer period of time without any trouble. They are dependable and trust worthy. It gives best results even under critical conditions.

Switch.
This is a small 2 pin push button switch which is useful for using in bread board circuit for reset in controllers. The capability of switching on/off push button is perfect for supplying power to a circuit. After pressing or pushing, it gets connected to the circuit and allow current to pass through.

NE555 Timer IC.
The NE555N timer chip is a 8-pin device which is stable and extremely robust. Production of delay timers, power supplies and converters are operated through monostable bistable or Actable multivibrator. Due to the endless list circuit requires some form of time control.

Design
We found that a PPE kit and sanitizer machine has launched for this situation which is not that much appropriate, so an effort has been taken to make more effective product which help to sanitize automatically through polycot using timer. The timer used here is basically to control the time for the flow of the sanitization liquid in the body. When the liquid starts flowing a fixed time will be maintain to start and stop the flow of liquid.

Fig.12. Circuit Design
The battery supplies the power to the switch as well as to the DC motor. DC motor will get ON by supplying the power to the push button switch during the time of the flow of the fluid. The switch is fixed in the suit to start the flow of the liquid sanitizer and gives the LCD will control the flow of time of the fluid in the body. The relay module activates the DC motor automatically. Then the sanitizer liquid starts flowing through the hose pipe and the liquid scattered by the nozzle spray. The fluid then comes out as a fog through the nozzle and spread in the body. This operation is called "Automatic Sanitization System". All the components that are Timer, Power supply, Push button switch, DC Motor and LCD Display are connected by Arduino Uno microcontroller and will link all the components. The NE555 timer chip helps to control the time system. The micro Controller gets signalled by the relay module. The entire system enables or disables by the control of the push button switch and timer. The LCD will be controlled by the Arduino keypad which will control the time of the flow. If it flows in liquid form moisture will form. So, to fix the problem ultrasonic mist maker is used in the sanitizer solution.

Results and discussion
By facilitating automatic sanitization circuit, the user accesses the sanitizing liquid automatically on the body without the need of operating or touching the sanitizer manually. The feature ensures that viruses have no chance of spreading through physical touching of the sanitizer bottle and its operating parts. However, to be automatic, the system will require a push button switch to start the flow of the liquid on the body. This automatic suit not only helps in sanitizing automatically but also it helps the users to feel relax. As the user wearing the suit for long time can get suffocated and feel uneasy. So, to get rid of suffocation mist maker is used to free the body from moisture.

Conclusion
The entire circuit will work efficiently with all the components. The feature ensures that viruses have no chance of spreading through physical touching of the sanitizer and its operating parts. The future development can be done by using mobile app development. The more fastest sanitizing process and the more accurate results will be acquired. The fast the process will be, it will be more time consuming.
