Hey Mario and CW2,
Thanks for responding to the post, and I've figured out that the DHT-22 uses a weird 1 wire protocol, and that the lack of precision with the .NET framework is going to be a deal breaker. So I would recommend avoiding this sensor despite it's alluring price.
Therefore, I have decided to go with an analog approach. I've decided that dealing with an analog voltage signal should be much easier than trying to decode some strange 1-wire protocol or do any kind of bit hacking which is way over my head at this point.
So, I've ordered a new set of sensors. I have purchased a 10K thermistor, the SEN - 00250 to be exact. I have also purchased a humidity sensor in the form of a HIH-4030 Breakout Board. I'm planning on reading the 10K thermistor using a simple voltage divider with another 10K resistor. I'm hoping that will give me the right voltage range and close enough accuracy for measuring temperature +/- a few degrees F.
I'll let you know when I get everything set up.
