This dispenser is contactless and will spray sanitizer for sanitization of hands/whole body while entering into the buildings like Hospitals, Office complexes, shopping Malls, auditoriums, public places, apartments, schools, colleges, places of worship, other public places etc. As the global Covid-19 crisis continues to unfold, washing and sanitization of hands have become an absolute necessity in daily affairs. Automatic mist-based sanitizer dispensing systems is very useful resource in the fight against corona virus and contagious diseases. This contact less dispensing system helps to sanitize hands without getting in contact with the sanitizing surfaces and will help to reduce spread through cross contamination. Key Words: (Covid-19, HC Sr-04 Technology, Counter) 1. INTRODUCTION Corona Virus disease (Covid19) is wreaking havoc in the world. Ever since WHO announced it as a Pandemic disease and many cities are under lockdown, people are not able to step out of their homes and already thousands have lost their lives [1]. As the global Covid-19 crisis continues to unfold, washing and sanitization of hands have become an absolute necessity in daily affairs [2]. Automatic mist-based sanitizer dispensing systems is very useful resource in the fight against corona virus. This contact less dispensing system helps to sanitize hands without getting in contact with the sanitizing surfaces and will help to reduce spread through cross contamination. This contactless dispensing unit sprays alcohol-based sanitizer when both hands are placed under it. The aerated mist-based formula uses only 5- 6ml. of sanitizer ensuring optimum usage. It releases full cone spray mist for 12 seconds in single operation. Contactless technology works on Ultrasonic sensor to ensure zero touch, high operational precision to completely disinfect both hands at once. It could be wall mountable with LEDs displays to indicate on/off status and the progress of the process. The capacity tank ensures longer duration of usage thus eliminating hassle of refilling it frequently. The sanitizer container allows displaying the quantity in it. Poor or inadequate hand washing and/or hand hygiene is known to be problematic in hospital settings, and is a major source of infections contracted while patients are admitted to a hospital. While hand washing and hygiene policies and training are important and can be effective in reducing the spread of infections, the problem of infections due to unsatisfactory hygiene of staff, medical professionals, and even patients continues to be problematic [3]. It is known to place hand washing stations and hand sanitizer dispensers throughout medical facilities including in examination rooms, hallways, lobbies, and even patient rooms. However, such systems are purely mechanical and are incapable of providing an automated means of establishing accountability of good hygienic practices. The need of touch-less automatic dispenser is identified after observing that it is the point of contact for contamination. In this paper we present a novel design of automatic hand sanitizer dispenser with counter circuit which provide information regarding number of persons in particular building. The circuit includes an ultrasonic sensor HC-SR04. The sensor senses the proximity of hands under the machine. The machine is designed for wall mount at a height of 4ft such that anyone can reach to get sanitizer dispense. The sensor send signal to the microcontroller and the controller takes decision to actuate the pump and valve simultaneously to dispense the liquid sanitizer through a mist nozzle [4,5]. 2. Automatic Sprayer Why? We all know that hand washing is a key component to public and personal health. Hospitals, clinics and other medical facilities benefit from patients, staff and visitors reducing the number of germs and contaminants on their hands. Offices, administrative buildings, foodservice spaces and other workplaces benefit from customers and employees with clean hands. Regular hand washing helps fight the spread of viruses and bacteria that can cause illness, reduce workplace productivity and affect morale.  Automatic sanitizer sprayer does not have to be touched in order to be activated. This touch less technology reduces that number of germs, bacteria and viruses people come into contact with. Manual sanitizer and bars of soap can harbor the dirt and germs of the last person to use them, spreading them to the next user.  By this we reduce the spreading of corona virus and many more spreading viruses from one to another person in very efficient and effective way.
