4/11 Temperature Measurement System Design

       The purpose of this lab is observe the resistance change of Thermistor as the temperature changes. Then plot the graph Temperature VS voltage.

1. Thermistor Characterization provide the measured sensor resistance variation over the specified temperature range.

2. Wheatstone Bridge Design
    a. sketch the circuit to convert resistance variation to voltage variation. Include desired and actual values for circuit components

    b. Provide the measured output voltage for nominal temperature

       

    c. Provide the measured range of output voltage over specified temperature range.

        We can find them from the video above.

3. Difference Amplifier Design
     a. Provide a sketch of difference amplifier circuit, including desired and actual values for circuit components

Summary

            In today's class, we learned the concept of amp circuit and how to replace a the amp circuit with resistance. Then, we did some examples of how to deal with the amp circuit.
