    Hello all I am currently working on a way to get an accurate reading from my RTD sensor. Here is the link for the PT100 RTD I have already purchased.

    Here is another link of how I think I am going to get an accurate reading into my microntroller.

    I have two questions, one is kind of silly, and the other is whether or not anyone thinks this will work.

    1. on this RTD there are three wires, 2 red and 1 white, if I am using the circuit in the example shown, which wires go where into the microcontroller and circuit.

    2. does anyone have any experience with this or another option.

    Thank you for any responses.

    Go visit Omega. Very good source for this sort of thing.
