This document summarizes the design and development of an automatic hand sanitizer dispenser. The system uses an Arduino Uno microcontroller, ultrasonic sensor, and peristaltic pump. It is designed to automatically dispense sanitizer when a person's hand is detected within 90cm of the sensor. The total estimated cost is 1500 BDT. The automatic dispenser is intended to help promote frequent hand sanitizing during the COVID-19 pandemic in a low-cost way.

6. Feasibility
The COVID-19 pandemic has dramatically changed the dynamics of
the hand Sanitizer Market . According to research. Bangladesh Hand
Sanitizer Market size is expected to witness considerable growth
during 2020-2023.
This technology in Bangladesh hand sanitizer market trends,
opportunities areas and market driver which would help the
stakeholders their market strategies according to the current and future
market dynamics.

7. Conclusion
• The situation of worldwide, sanitization commodities should be installed in
each and every corner of the sphere , be it an industry , a corporate office , an
educational institute or a shopping mall.
