PROTÓTIPO DE UMA CAMARA DE RADIAÇÃO UV-C PARA DESINFECÇÃO DE OBJETOS

Abstract

Hospitals use germicidal lamps at ultraviolet wavelengths (UV-C - 254 nm) to sterilize equipment, water and the environment in operating rooms. The food and medicine industries use them to disinfect various types of products, containers and packaging. This technology is currently being used to disinfect environments, medical and hospital equipment and protective equipment in common use in the face of the current COVID-19 pandemic. In view of the UV-C applications to perform sterilization of environments and objects, this project involves the development of a prototype using a hardware electronic prototyping platform of a chamber with portable UV lamps for disinfecting objectives. This prototype consists of a hardware module and a software module. In the hardware module, the necessary components for the assembly of the physical system were evaluated, as well as its basic functions, such as the activation of lamps and safety devices, while in the software module, the timing system, the activation and shutdown control were developed. of the lamps, the user interface and security, the exposure to radiation through a magnetic reed switch sensor to check the state of the door.
