This document outlines a project to develop an automated hand sanitizer device and non-contact temperature detection system for supermarket entrances. The system aims to provide touchless sanitization and temperature checks while monitoring sanitizer levels and quality. It will be developed over 3 months using components like a liquid pump, proximity sensor, and temperature sensor. The device will be tested for accuracy of temperature readings, sanitization timing, liquid level detection, and ignition detection before finalizing. The system is intended to improve hygiene and health protections while reducing employee workload during the COVID-19 pandemic.

OVERVIEW

5. 1.1 PROBLEM
SPECIFICATIONS
 The government has imposed regulations on the hygiene of consumers as well
as employees in supermarkets.
 It is mandatory for customers to wash their hands and check the temperature
before entering the supermarket.
 Those 2 functions are done by manually.
 Major drawbacks in current system :
1.Wastage of the sanitizer liquid
2.People always touched the dispenser
3.Damage of the device.
4.Employees exposure to the virus.

6. The proposed device has the following functions.
 Automatic release of sanitary gel.
 Automatic measuring of body temperature.
The proposed device has following security measures.
 Automatic measuring sanitary gel level.
 Automatic measuring sanitary gel quality/activeness.
 Inform the relevant authorities via SMS after the required ranges of the above
components have been changed.
1.2 SOLUTION
OUTLINE

7. 1.3 OBJECTIVES
 Integrate automated sanitizer container and human body temperature
detection system for supermarkets within 3 months that provides;
 Touchless sanitizer spraying to maintain good hygiene.
 Measure temperature and sanitizer level of the sanitizer container to
provide protection and reliability for the sanitizer container.
 Measure and display customers and employees body temperature to
provide better health protection from COVID19 pandemic.

8. 2.0 BACKGROUND

9.  According WHO providing hand sanitization is important in companies like
supermarkets[2]
 By providing the automated solution for it will help to provide comfortable
mechanism for hand sanitization[4]
 Automated hand sanitizer device can be developed without an
microcontroller like ATMEGA328P[1]
 To integrate it with non-contact human body temperature detection should be
used an microcontroller
 This non-contact temperature sensor accuracy depend on the distance[5]
 To improve it proximity sensor should be used
 Ultra sonic sensor is the best solution for liquid level detection in non-
contacted manner[3]

10. 3.0 RESEARCH
QUESTIONS

11. 3.1 WHAT?
What are the advantages of automated hand sanitizer dispenser?
 Improve hygiene
 Encourage usability of sanitizer dispenser
 Economical
 Ensure customers and employees Health protection
 Improve safety.
 Improve reliability
What kind of procedure should follow before dispensing sanitizer liquid
to hands?
 Detect the body temperature
 If the body temperature is in fever level generate an alert
 Detecting hands of a customer or employee when he or she place their
hands
 If the body temperature is normal disperse the sanitizer liquid

12. 3.2 HOW?
How to detect a sanitizer container liquid level in non-contacted
manner?
 Three different types of non-contacted liquid level detection methods
 Non-contact capacitive liquid level sensing.(FDC1004)
 Liquid level monitoring using Laser Time-of-Fight (ToF) sensor
 Liquid level monitoring using ultrasonic sound.
 Among them ultrasonic is liquid level detection is the best
How to improve the reliability and the safety of the device?
 Implement a notifying mechanism about sanitizer liquid level
 Implement a notifying and alarm mechanism for sanitizer liquid
ignitions

13. 3.2 HOW? How to prevent the sanitizer liquid ignitions?
 Two situation that there is ignition may occur in a sanitizer liquid
container;
 Sanitizer liquid temperature is higher than its’ flash point.
 Fire ignitions or electrical sparks near by the sanitizer container
 Using liquid temperature sensor and flame sensors these situation can
be detected.
How the activation energy of sanitizer liquid affect to the ignition of the
liquid?
 If the temperature of the sanitizer liquid is higher than the evaporation
temperature of the sanitizer liquid, liquid activation energy decreases

the level sensor are monitored and relationship between them is concluded
• Observe whether the signal is received when the level of the sanitary liquid
drops

25. 5.2: EVALUATION
 The device allows customers to quickly and easily complete their hygiene
precautions
 The safety and reliability of the device are maximized by the ability to notify
