Automatic Alcohol Hand Sanitizer Dispensers With & Without Microcontroller
Main Article Content
Abstract
Hygiene for humans is necessary to maintain human health to keep the body clean and be free from germs without spreading the disease to various places, especially during this time with the spread of COVID-19 with increasing numbers continuing to evolve species to be able to reproduce and survive. For this reason, this research article therefore designed and invented an automatic liquid alcohol dispenser with and without a microcontroller, which would assist in preventing germs from spreading from the hands of people in that community by not having to touch any part of this device while using it. An Automatic Alcohol Hand Sanitizer Dispenser with a Microcontroller (AAHSDWM) has advantages for adjusting the amount of alcohol liquid by coding and speeds up installation faster than in the first stage. An Automatic Alcohol Hand Sanitizer Dispenser without Microcontroller (AAHSDWoM) has advantages such as cost savings of up to 30%, ease of configuration and maintenance, higher overall average user satisfaction scores, and ease of mobility due to the use of rechargeable batteries. In addition, AAHSDWoM is suitable to make a low-cost product for commercial use. These devices would then dispense liquid alcohol to the users’ palms. Test results show that the unit is 100% efficient, providing up to 1,000 alcohol dispensing services.
