BACTERIA STERILIZER WITH UVC

Abstract

This article presents the design and development of a UV-C germicidal device emphasizing efficiency in bacterial elimination and operational safety. The proposed system integrates Arduino Uno R3 microcontroller technology with dual operating modes: manual and automatic. The device features four 6W UV-C lamps and a safety mechanism utilizing limit switches to prevent unintended exposure to UV radiation. Experimental results demonstrate the device's ability to effectively eliminate coliform bacteria and Escherichia coli, reducing bacterial counts to 0 CFU/ml within 60 minutes. The average UV-C intensity was measured at 3,466.16 µW/cm². This innovation focuses on enhancing sterilization performance across various material types, simplifying usability, and establishing new standards for UV-C sterilization devices    suitable for general and community use.
