Lab Op-Amps Extra Credit

Intro:

The purpose of this lab is to use an LM 358 thermal sensor opamp for temperature measurement.  Lm 358 can run 0-5V and can measure 1⁰C  at 10mV.  We want to design an amplification that can measure between 15⁰C to 35⁰C

Analysis:

We were at least come close to room temperature with an error of about two degrees. 

The problem was there were fluctuations of the temperature readings.
