UV detection devices and methods

A portable UV detection apparatus comprising:

• a skin type measuring device comprising a skin sensor, the skin type measuring device being configured to determine at least one characteristic of a person's skin when the skin is placed adjacent to the skin sensor wherein the at least one characteristic of a person's skin determined by the skin type measuring device comprises both an erythema measurement and a melanin measurement wherein the skin type measuring device determination is based, at least in part, on determining an amount of ambient ultraviolet radiation present in an environment to which the person's skin is exposed and comparing this to an amount of the ambient ultraviolet radiation reflected from the person's skin;
• a UV detection device comprising a UV sensor, the UV detection device being configured to measure an ultraviolet ray quantity present in an environment;
• and
• a controller in communication with the skin type measuring device and the UV detection device, the controller, based on data received from the skin type measuring device, data received from the UV detection device as well as data from a user including the length of time the user will be exposed to the environment, being configured to output a suggested skin protective measure to the user based upon the length of time the user will be exposed to ultraviolet rays within the environment.
