Photoresistor or Phototransistor?

Are the light sensors really photoresistors as the article currently says? I couldn't find any reference to a specific type of light sensor in the patent, there's no linked forum thread discussing the board, and I've never seen a photoresistor with a plastic housing. To me it seems more likely that they'd be phototransistors. Maybe someone who owns one of these boards could desolder one and test its behaviour to determine what type of sensor it really is. --Ratfink (talk) 14:10, 24 February 2016 (CET)
