This document describes an IoT-based smart hand sanitizer dispenser. It uses an ultrasonic sensor to detect hands and dispenses sanitizer from a pump. An ESP8266 connects the device to the internet. The objectives are to create an automated sanitizer that can detect liquid levels and refill itself. It will send notifications about the bottle status and reminders to sanitize. Software includes Firebase, NodeMCU, and Python for machine learning to predict emptiness. Hardware consists of ultrasonic sensors, motors, relays, batteries. Members will work on Android and software programming, hardware testing and control. The team has started circuit design and plans to test and build a prototype while further studying programming aspects.

1. IoT Based Hand-Sanitizer
Smart-Home Sanitizer

2. 1.1 Introduction
• Hand sanitizers were first introduced in 1966 in medical
settings such as hospitals and healthcare facilities.
• Alcohol-based hand sanitizer is more convenient
compared to hand washing with soap and water in most
situations in the healthcare setting
• Alcohol gel can catch fire, producing a translucent blue
flame. This is due to the flammable alcohol in the gel.
Some hand sanitizer gels may not produce this effect
due to a high concentration of water or moisturizing
agents.

3. 1.2 IoT Based Introduction
• In this project, we will build an Auto Hand Sanitizer
Dispenser.This project will use ESP8266, Ultrasonic
Sensor, Water pump, and Hand Sanitizer. An ultrasonic
sensor is used to check the presence of hands below
the outlet of the sanitizer machine. It will continuously
calculate the distance between the sanitizer outlet and
itself and tells the ESP8266 to turn on the pump
whenever the distance is less than 15cm to push the
sanitizer out.
• ESP8266 is used as the main controller, it will directly
connect your module to the internet. We previously
used it to build many IoT based projects using
ESP8266.

4. 2. Objective
• The of this whole project is to
create an IoT based hand
sanitizer.
• The sanitizer is basically a
smart which is capable of
detecting the alcohol inside the
bottle.
• The whole model is created to
prevent the person of getting
contaminated.

5. • As it is a server based project we can review the
previous data to ensure the changes occurs in the
values.
• The system is capable of refill the bottle by itself.
• Also it sends you the notifications for the
emptiness and time to time maintainence and
remainders for hand sanitizing.
• Since it uses the machine learning techniques it
will predict the emptiness of the bottle.

8. Till now what we have done?
• We have find some realted documents with this
project.
• We have created the circuit diagram for our
project.
• Also we have planned to create the model as
soon as possible.
• Also we are studying on the different aspects of
this project such as programming related to
Android, javascript & python for ML.
• As it's an embedded project we are working for
the testing part also we have create the testing
team also for this and also learn something
meaningfull also for the different aspects of
testing.
Further Plans!!!!!!!!!
• We will test the circuit which we have design
on fritzing.
• We will make one small dasboard for
displaying the data.
• We will test the working of the project by
integration testing.

9. Conclusions
• We have test and simultaneously research all the things which is required
for our project building.
