Hello Again,
I am trying to use an rtd sensor to measure temperature up to 600 degrees F, then measure it with an It can be off by about as much as 10 degrees at 600. I have found that rtd sensors are the cheapest way to accomplish this.
I see many ways to wires these depending on accuracy. Is it possible to just wire one lead to the A2D pin of the microchip and the other to ground? If so, how much would that effect it? Below is the link of the digikey part Im looking at. I also see they have they same one with same specs except 100 ohms. What exactly does that mean?
Thanks,
Pat
