The pandemic caused by the COVID-19 disease has forced the organization of humanity in order to fight against its spreading. This project was born with the will to help local business and small institutions, so that they are able to implement anti COVID-19 measures economically. The main aim of this work is to evaluate whether it is possible and economic to create (1) an automatic system of capacity control and (2) an infrared digital thermometer, through the use of low-cost technologies: Arduino, an open-source electronics platform, MIT App Inventor, an online tool useful to create mobile apps, and 3D design and printing. The results showed that the automatic system of capacity control was the only one built with a low cost, since the infrared digital thermometer turned out to be 2,45 times more expensive in comparison to one similar of the market. The conclusions revealed the wide range of applications the Arduino platform has, as well as the easy accessibility it offers to people with little previous technical experience. Finally, the research question could not be answered affirmatively. Further investigation should be done so as to (1) reduce the total cost of the systems, possibly using low-cost 3D printing services and alternative suppliers to those used in this project, and (2) to improve them so that both can comply with all the legal regulation.
