Implementación de un prototipo de dispositivo electrónico para la desinfección de monedas y billetes.

Abstract

The purpose of this degree work was the construction of a prototype of an electronic device for the disinfection of coins and paper money, circulating money is one of the main carriers of microorganisms that cause various diseases, it has been considered the application of ultraviolet light type C as a means of disinfection, so it does not generate damage to the structure of bills and coins, it is also capable of effectively eliminating viruses, bacteria, fungi and protozoa. The prototype is divided into blocks, the charging block allows to energize the prototype by means of the electrical network; the processing block made up of development cards that control sensors, capable of detecting the presence of money and control the actuators, responsible for the exposure using lamps with a capacity of 25W/m^2. The display block with a screen shows information of the amount of money, it also has an audible alarm in each completed process, and the storage block has adequate deposits for the money; the minimum exposure dosage was considered. For the validation of the tests carried out in the research process, accepted values of pathogen inactivation from experiments performed in other literatures were taken as reference, giving as a result 100% efficiency in the disinfection and counting of coins and bills; further, it was found that increasing the exposure time and the intensity of the lamps improve the results considerably. It is concluded that the implemented prototype is reliable, stable, and acceptable to sanitize money. It is recommended for future improvements of the prototype to incorporate artificial intelligence for bill counting and a system that wraps and seals the coins.
