UV dosimetry system with sensor data correction

A non-transitory computer readable medium having computer executable instructions stored therein, said instructions control at least one processor to implement a method, the method comprising:

• measuring a UV intensity irradiating on a device;
• detecting if a user of the device is in a shaded condition or an unshaded condition based on a shade detector embedded in the device;
• correcting the measured irradiating UV intensity if the user is detected to be in the unshaded condition;
• and
• measuring a sun exposure time based on the corrected UV intensity over a period of time;
• wherein the shade detector comprises a temperature sensor configured to measure an ambient temperature, and the device is adapted to detect a change of the user's environment if a newly measured ambient temperature is determined to deviate significantly from a trend of recently measured ambient temperature.

A system comprising:

• a wearable unit comprising a circuitry for measuring irradiating UV intensity;
• and
• a mobile computing unit communicating with the wearable unit;
• wherein the wearable unit comprises a shade detector configured to detect if the wearable unit is in a shaded condition or an unshaded condition;
• wherein the mobile computing unit is adapted to correct the measured irradiating UV intensity if the wearable unit is determined to be in the unshaded condition;
• wherein the mobile computing unit is further adapted to measure a sun exposure time based on the corrected UV intensity over a period of time;
• wherein the shade detector comprises a temperature sensor configured to measure an ambient temperature, and the mobile computing unit is adapted to detect a change of environment of the wearable unit if a newly measured ambient temperature is determined to deviate significantly from a trend of recently measured ambient temperature.
