I don't know.  When I soldered my kit, I got strange results.  My
work area is around 25 deg C, but the sensor (or the PIC or a
combo) says it's between 40 to 60, and what makes me wonder if
I screwed up something is that if I were to put the sensor on
my hand, the sensor readings go negative.   (Negative sensors
isn't possible, unless I'm frozen.)

Thanks for the info.
