Abstract
This disclosure relates to measuring ultraviolet (UV) exposure. One example system includes an electronic sensor chip that includes a UV sensor that measures a UV intensity reading, an inertial measurement unit that acquires movement data of the UV sensor, and at least one processor. The system further includes a light pipe that guides light towards the UV sensor and a diffuser that has an angle-dependent transmission function and covers an end of the light pipe. Example operations can be performed by the processor include determining a solar incidence angle between a direction of the sun and a normal direction of the UV sensor, computing an estimation of a maximum UV intensity at normal incidence based on the UV intensity reading, the solar incidence angle, and the angle-dependent transmission function of the diffuser, and outputting a UV index based on the estimation of the maximum UV intensity at normal incidence.
