Practical Signal Conditioning

Goal:
We were given a circuit component LM35 that delivered a voltage equal to that of the temperature in Celsius. However we are American we like to do things differently so we must change the temperature reading from the Celsius scale to Fahrenheit. We want to use and op amp to perform the operation converting Celsius to Fahrenheit. F = 1.8C + 32
LM 35 

Circuit diagram





Here we calculate R1 and R2 

Complete circuit with a voltage that is .782 Volts which is roughly what we were expecting

Since the resistors we used did not have the same exact values that we found we needed in our calculations our conversion was slightly off.
