Design of Band-type Device to Measure UV Index and UVB Irradiance in Everyday

Abstract

UV (Ultraviolet) is known to negatively affect human body. Especially UV A promotes skin aging, and UVB enhances skin cancer prevalence. UVB, however, offers a useful function to support vitamin D production within human body. Therefore it is needed for people to be exposed to UV through proper outdoor activities and to acquire UV environmental information surrounding them. In this regard, this study devises a band-type device to measure UV irradiance in everyday life. The proposed device consists of a band to wear the device on user's wrist, arduino-based micro controller, and a UV sensor measuring UV irradiance. The proposed band-type device is expected to induce appropriate outdoor activities in the UV environment that does not harm human body by offering precise information on UV index and UVB irradiance surrounding users.
