  • I've bought 4-5 of these for use in our lab, one is mounted on our sun tracker controller, and works great (using it with 4 photo-resistors to give the sun's relative location and irradiance.) but the last 3 have been duds.. The diode reads either as on open or shorted circuit. We hook them up to arduino's, so even a crossed wire hook up should only be 5V, which I don't think can burn out a photodiode. Any idea what is happening? Here are pics of the good and bad sensor (https://plus.google.com/107935709908498477582/posts/5fXwMVz4Yfn ). Could overheating the board when soldering do this?
