Hi,
5v is coming in on green, but I don't believe I have the sensor backwards. Green is connected to pin 3 (pin 1 is at the top in the picture). When I put the board back into the parasitic configuration, the sensor still appears to be working and accurate when compared to another temp sensor I have in the same space.
Just to clarify further, in that picture Green is connected to 5v and sensor pin 3, Blue is connected to Arduino D3 and sensor pin 2, and White is connected to Arduino GND and sensor pin 1.
Thanks.
Andy
