This document describes an automatic hand sanitizer dispenser system using an Arduino Uno microcontroller. The system uses an ultrasonic sensor to detect when a hand is placed within 90cm of the dispenser, which then activates a servo motor to dispense the sanitizer. A flowchart shows the detection and dispensing process. A circuit diagram and component list with estimated costs are provided. The document concludes that such automatic dispensers should be installed in various public places to help prevent the spread of COVID-19 through improved hand sanitization.

The COVID-19 pandemic has dramatically
changed the dynamics of the Hand
Sanitizer Dispenser Market. According to
research, Bangladesh Hand Sanitizer
Market size is expected to witness
considerable growth during 2020-2026.
This technology in Bangladesh hand
sanitizer market
trends, opportunities areas and market
drivers 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 an
shopping mall.
