Measure ultraviolet light in three separate bands with the AS7331 on this Mini breakout. Individual photodiodes and interference filters serve the UVA, UVB and UVC channels. The compact board keeps the three-channel measurement approach in a half-inch by one-inch footprint for projects where enclosure space is limited.
