Device and system for personal UV exposure measurements

A system for determining personal ultra-violet (UV) radiation measurements, comprising:

• a measurement device configured to measure UV irradiation;
• and
• a terminal device configured to receive or capture an output of the measured UV irradiation from the measurement device and to determine a specific user's personal UV exposure risk level based on at least the measured sun irradiation and information of a skin type of the specific user,
• wherein the measurement device includes a surface that includes a plurality of different sections that each have a different sensitivity to UV radiation exposure, wherein each of the plurality of different sections are configured to display a different color in response to the UV radiation exposure, the surface further including a plurality of different fixed reference colors to each indicate a different corresponding UV exposure level, the plurality of different fixed reference colors being embedded among and intermingled with the plurality of different sections that each have a different sensitivity to UV radiation exposure and
• the terminal device includes
• an image capturing device configured to capture an image of the plurality of different sections as the captured output of the measured UV radiation and the plurality of different fixed reference colors, and
• processing circuitry configured to determine the measured UV radiation based on performing image analysis of the captured image by comparing a color of the plurality of different sections with the plurality of different fixed reference colors.
