Hi Nate,
You might also find this interesting. The temperature sensor looks like
a plastic transistor package and is standing out from the board in order
to sense the air temperature and is therefor easily pushed over. Keep an
eye on it.

Hi Peter,
I found the problem with the board that had a short on the + 5v supply.
It was due to the fact that the temperature sensor had been squashed flat
to the board shorting its' pins together. I guess we'll have to keep an
eye on the sensors or find some way to support them.
After I got that straightened out I found that one MQT wasn't giving the
right output so I have replaced it with the second one you sent me. This
chip must have been unhappy about one of its' supplies not being there
because it was O.K. when the modules were first received.
