Measurement application for UV-C irradiation intensity evaluation

This paper presents a measurement application designed to evaluate Ultraviolet-C (UV-C) radiation intensity generated by commercially available lamps. Our work was done in the context of proliferation of different devices and technologies deployed with the purpose of virus (especially SARS-CoV-2) and bacteria inactivation. The proposed system is based on the UV-Tiamo-C6 sensor module, a professional device designed for purification lamp control. The intensity characteristics for two types of sources (1x36W and 2x36W) were investigated in relation with the distance from the source. Furthermore, the 2D space distribution of the intensity was analyzed by means of a customized mobile platform built on an iDrive Rock Climber vehicle. Other facilities of the proposed measurement experiment include live video transmission, automated data saving/analysis and remote control. Functionality tests performed in the laboratory confirm that the proposed system was properly designed and implemented. As future development, we will focus on correlating the effectiveness of a disinfection device, based on such UV-C lamps, in relation with exposure time, distance and target colonies type.
