• aim
• previous system
• proposed system
• Block diagram
• Individual blocks
• circuit diagram
• Working principle
• Software requirements
• Results
• Advantages
• Disadvantages
• Applications

3. Problem statement:
• Over the last two years the COVID-19 pandemic has been
spreading chaos all around the world.
• There are countless infections and unfortunately many casualties.
• One of the most important measures suggested by the World Health
Organization is constant hand washing with either soap or hand
sanitizers.
• But one of the most significant problems is the way we do it and that
is by physically touching the dispenser which eliminates the whole
purpose of the action and even creates a great risk of infection.
• So this project is to create something using an Arduino uno board
that could combat this problem.

4. objectives
• it is budget friendly to do this automatic hand sanitizer dispenser machine.
• In this tough times everybody is to maintain the contact less with object by this
automatic hand sanitizer without touching we can sanitize our hands.
• It is an eco friendly product everybody can afford to buy this automatic hand sanitizer
dispenser .
• this can be used in many areas in our day to day life like schools , home , work places
,hospitals and other etc.,.
• the most goal doing the project was to use this advanced technologies to develop the
automation machine is to keep more hygiene and clean in this present times.
• this automatic dispenser have low price comparing any other tools and instrument .
• the wastage is very less ,easily can change the liquid in the bottle without any technical
support.
• This is always an smart way of protecting from covid19 virus.

5. Literature survey:
• In [1], the paper mainly says about the hospital grasped infections, which is
about 2 Million Patients per year and also says that it is 8th leading cause
for deaths annually in USA.
• It also says that handwashing is important and also effective with proper
hand washing steps, but washing with soap and water is time consuming
for peak hours in hospitals.
• This paper also showed the effectiveness of the alcohol based hand
sanitizers, which reduced infection rates by whopping 30%.
• They used hand sanitizers with 60 to 70 percent ethanol or isopropanol for
reducing significant number of pathogens.
• The patients were also given about 4.25 ounce containers of hand sanitizer
alongside their beds For 10 month period of using hand sanitizers showed
a result of 36.1% infection reduction.

6. Methodology and
implementation
• The corona disease is a major problem future world.
• Presently there is no medicine or vaccine found in the resent world.
• As there is a severe attack in this world, the people are suffering from the corona
disease.
• As there is an impact in using the hand wash sanitation by foot or by pressing the
sanitizer bottle used to have a spread of the virus disease from one human to another
• The Easy Non-Contact Automatic Hand Sanitizer Dispenser or Automatic Soap
Dispenser with Arduino

7. Proposed system Block diagram
Arduino uno
Ultrasonic sensor
Reset
LCD
l293d
Pump motor
Regulated power
supply

8. Working
• We will be using the ultrasonic sensor for the detection of the
hand.
• The distance for detecting the hand can be easily set in the
Arduino
• when the sensor detects the hand it will turn on the hand
sanitizer, and
• when the hand is not present in front of the sensor the hand
sanitizer will be turned off.
• We will be using a DC water pump for this purpose.

9. Schematic diagram:

10. Algorithm:
• Power on project circuit using 5volt 1 amp adaptor
• Initialize ultrasonic sensor ,initialize Arduino , LCD, Pump motor
• Check for hand near sensor
• If hand detected dispense solution
• If no hand display monitoring on LCD

11. Flow chart
•
•
• yes no

12. Observations
• Project works well when hand is presented near sensor
• It dispenses solution as long as hand is kept near sensor
• It dispenses for 3 seconds as programmed in controller
• Pump motor also functions accurately
• As programmed less than 10cm it works on that reading
• Ultrasonic sensor works accurately

15. Results

16. Advantages
• It is Non contactable.
•
• Protect from COVID 19.
•
• Infrared sensor technology.
•
• Design is compact.
•
• Easy wall mounted installation
•
• Available in different sizes.
•
• User friendly.
•
• Maintenance is low.

17. Disadvantages
• Dry skin
• Fire hazards

18. Applications
• It can be used hospitals.
•
• Used in public locations
•
• Also used in School & colleges
•
• Use in Airports.
•
• Used in hotel and restaurants.
•
• Shopping malls.
•
• Banks.

19. Conclusion
• Implementing of Contactless Automatic Hand Wash Dispenser for Sanitation
is efficient and the cost price is minimized.
• It works like the normal contactless automatic machine.
• The human gets the limited sanitizer liquid for sanitation in hand, to wash
the hands and to protect themselves from the corona disease.

20. Future scope
• Hand sanitizer machine can be connected with IOT for live update
about corona cases
• This machine can be connected with big LCd screen to display
precautions to be taken during pandaemic
• This machine can also be connected with voice update about virus for
illiterate persons
