Abstract
This paper presents a solution for monitoring of solar ultraviolet (UV) exposure and alerting about risks in real time. The novel system provides smart personalized indications for solar radiation protection. The system consists of a sensing device and a mobile application. The sensing device monitors solar radiation in real time and transmits the values wirelessly to a smart device, in which the mobile application is installed. Then, the mobile application processes the values from the sensory apparatus, based on a fuzzy expert system (FES) created from personal information (hair and eye color, tanning and burning frequency), which are entered by the user answering a short questionnaire. The FES provides an estimation of the recommended time of safe exposure in direct sunlight. The proposed system is designed to be portable (a wearable sensing device and smartphone) and low cost, while supporting multiple users.
Highlights
Sunlight is the electromagnetic energy given off by the Sun and plays a very important role for the life on our planet
Even though UV radiation is a part of sunlight, people cannot perceive it directly because this specific wavelength range is blocked by the cornea and the lens of the eye
UV radiation is divided into nine different subtypes based on the wavelength range
Summary
Sunlight is the electromagnetic energy given off by the Sun and plays a very important role for the life on our planet. As awareness of the subject increase, people become accustomed to the idea that skin must be protected, and they seek more innovative ways of protection as they are not entirely prepared to abandon the idea of sunbathing (mainly due to the domestic implications associated with sun exposure such as tanning, and due to other reasons that include health reasons such as the metabolism of vitamin D). Individuals who are concerned about the health state of the skin of their face and body may want a definitive method to measure their exposure and minimize the risk of direct Sun contact at any time. The application processes the user characteristics and the data regarding the solar radiation and provides an estimation of the recommended time of safe exposure in direct sunlight.
