Diseño e implementación de un prototipo automático para la desinfección de manos mediante micro pulverizado.

Abstract

The present graduate research project was to design and implement a hands disinfection prototype using micro-pulverized due to the global crisis caused by COVID-19. The use of alcohol, gel, or disinfectants is suitable for disinfection without causing no damage to the skin to remove viruses and bacteria. Before prototype construction, the micro-pulverized was investigated, the necessary elements to implement it, and the best disinfectant liquid. The prototype has a body temperature measurement sensor, turning on an alarm if the temperature is high or when the level of the disinfectant liquid is low; additionally, it has an OLED screen in which the temperature and the level of the liquid are displayed. Based on the stability of the sensors that have a coefficient of variation within the range of 0.49 to 2.039%, being less than established of 15% according to the INEC, the prototype is stable; additionally, it has a GSM module, which sends an alert message from the device to maintenance personnel and security in a time of 2-3 seconds, in a distance of 4.4Km, from which a transmission integrates the message 100%. Finally, an economic analysis was carried out comparing with a device made in Europe called Higia; the presented prototype shows a saving of 65.62% in relation to the European device. It is recommended for future research that the prototype has a photovoltaic power system.
