Anatoliy Bula, a student at Lutsk National Technical University, majoring in Metalworking Equipment and Robotic Production Systems, has developed a portable ultraviolet radiation activity meter.
The development is based on a microprocessor board manufactured by the Telstra Creator Space division of the University of Melbourne, which was presented to Borys Prydalny, an associate professor at the Lutsk University, during his visit to the Australian university, LNTU reports .
The capabilities of this board and its compact form factor have prompted several ideas for using it as a basis for useful portable devices. Currently, the idea of a portable ultraviolet radiation level meter has been selected as one of the most interesting options for development. The possibilities of manufacturing other devices, including a nitrometer, have also been considered.
Too intense and prolonged exposure to ultraviolet rays causes deterioration of the human skin and the occurrence of its diseases. In particular, the key factor in the deterioration of the appearance of the skin is the so-called photoaging, which is a direct consequence of excessive exposure to UV rays. At the same time, this parameter must be controlled not only in sunlight, but also in artificial light. This is especially true for individual lighting devices with energy-saving technologies, and in particular at the end of their operation.
Currently, this is a prototype. The device is equipped with the simplest sensor, which provides the ability to indirectly measure the intensity of ultraviolet radiation of classes A and B, which have the most pronounced effect on humans. The design of the device also provides the ability to measure all three types of ultraviolet radiation: A, B and C when replacing the sensor. The meter’s operating time on a single battery charge is about 4 days.
The functioning of the working prototype revealed the importance of the orientation of the device towards the radiation source. To solve this problem, it is planned to use an additional element of the housing in the form of a light tunnel. In the next model, it is also planned to significantly reduce the size of the housing and improve its ergonomics. All project participants continue to work on its further successful development.
