The UV sensor in the Go Direct Light and Color sensor is the combined output from two sensors that together create an output with half-sensitivity range from 320 nm to 375 nm – spanning most of the region considered to be UVA.

UVA is the portion of the electromagnetic field with a wavelength between 320 nm and 400 nm, while UVB has a wavelength between 280 nm and 320 nm. This sensor is able to detect some UVB light (with less sensitivity), but should not be used for quantitative UVB measurements.
