Autonomní dávkovač dezinfekce založený na mikrokontroléru

Abstract

This bachelor’s thesis focuses on the design and implementation of an automatic disinfectant dispenser using the Arduino microcontroller. The aim of the project is to create a functional device that automatically detects the presence of a hand using sensors and subsequently activates a pump to dispense the required amount of disinfectant liquid. The theoretical part provides an overview of available Arduino microcontroller types, as well as descriptions of the sensors, modules, and actuators used to ensure the operation of the entire system. The project also includes an analysis of already implemented solutions of similar tasks, comparing their advantages and disadvantages. The practical part describes the design of the electrical circuit, programming code, and mechanical construction of the device. The result of the work is a compact and fully functional disinfectant dispenser, which can be used, for example, in offices or public spaces for contactless hand hygiene.
