  • Has anybody tried using these at high temperatures? The datasheet says they only go up to 85C. I am working on a coffee roaster and want to measure the humidity of the air coming off the beans. I figure the calibration will be way off at my temperatures which are up towards 150-200C, but I wonder if the sensor will even survive at these conditions. I can definitely make my own calibration curves, but from the datasheet it does not look promising from a sensor survival standpoint. But I thought I would throw it out there anyway because if there is any universal truth about makers it is that someone, somewhere, has already tried what you are going to try.

  • I want to connect this Arduino to a LCD screen. I am thinking the easiest way to do that would be via a serial connection: https://www.sparkfun.com/products/258 to a serial enabled screen: https://www.sparkfun.com/products/9067. I have used other Arduino and screens, but am a little hesitant here because there are so few I/O ports. I can't seem to find a good tutorial where folks have used lilypads and LCDs. Anybody have some experience?

No public wish lists :(
