UV light sensor

Hello Bolloonatics!

One of the high school student groups I am working with this summer is designing a microbiology experiment and would like to monitor UV flux during the flight. Does anybody know of any UV sensors that produce analog signals that could be measured with the Stratostar interface board, Hobo logger, or an analog pin of a microcontroller?

Thanks!

Bernhard

I found these UBA and UVB sensors:

They are 5 V, so I think it should be fairly easy to build and adapter for the Stratostar interface boards or Hobos, or connect them to a microcontroller. There is also a series of articles by Paul Verhage on how to make a BalloonSat with a LabPro.
