1. A mobile electronic device comprising:
- a transparent enclosure integrated with and disposed at an edge of a housing of the mobile electronic device;
a camera enclosed by the transparent enclosure, such that light passing through the transparent enclosure is captured by the camera;
a UV bandpass optical component fitted onto the transparent enclosure;
a processing unit configured to receive an analog signal representing the light captured by the camera, the processing unit including a UV bandpass filter module; and
a switch to select either the UV bandpass optical component or the UV bandpass filter module, such thatif the UV bandpass optical component is selected, the UV bandpass optical component is configured to filter out an-ultra-violet (UV) spectral component from the light and pass only the UV spectral component to be captured by the camera andif the UV bandpass optical component is selected, the UV bandpass optical component is configured to separate, in the processing unit, the UV spectral component from the light captured by the camera,wherein the processing unit is configured to process the UV spectral component based on known data to produce UV measurement data indicative of a UV exposure level.

Abstract
The present application discloses device and system embodiments that address mobile device integration considerations for various categories of UV sensors, including cameras, photodiodes, and chemical sensors. The UV sensors may use the functionalities of the existing in-built sensors in conventional mobile devices, and/or integrate additional components specific to UV sensing. By optimally positioning the sensors, UV sensing and other collateral functionalities (e.g., charging a photovoltaic cell integrated with the mobile device) can be realized in parallel.
