Abstract

A portable UV detection apparatus is disclosed. In one embodiment, the UV detection apparatus includes a UV detection device integrated with a skin type measuring device. A controller can be included in the apparatus that is in communication with the skin type measuring device and the UV detection device. The controller can provide information to the user regarding the amount of ultraviolet radiation present in the environment. In an alternative embodiment, the UV detection apparatus includes a UV detection device in conjunction with a light sensor. The light sensor can be configured to activate the UV detection device should light at a particular intensity be present in the environment. The UV detection device as described above can be configured to measure UVA radiation, UVB radiation, and/or UVC radiation.

Claims
