Methods, systems, and apparatuses for accurate measurement of health relevant UV exposure from sunlight

A system adapted for use in estimating erythemaly-weighted UV exposure:

• a sensor that is more sensitive to light with a wavelength from 305 nm to 315 nm than to light with a wavelength outside of 305 nm to 315 nm;
• and
• a non-transitory memory having stored therein a computer executable method, the computer executable method adapted to receive as input information that is indicative of an irradiance measured from the sensor, and to estimate erythemaly-weighted UV exposure using the information.
