Measurement push and pull forces on automatic liquid dispensers

<span lang="EN-US">Since the COVID-19 pandemic, automated liquid dispensers have been increasingly developed to assist transmission prevention. However, data availability of automatic dispenser mechanism's technical characteristics is not yet widely available. This causes frequent over or under design in its development. Therefore, we specifically measure push and pull forces engineering generated by mechanism. A wire mechanism-based apparatus was used experiment. load-cell sensor detect force that occurs from a servo motor controlled microcontroller.
