I am a mechanical engineering student and I'm quite bad at electronics so I decided to post here. For my dissertation, I require 2 circuits using the same 5.7 V DC power supply. One of the circuits is a temperature sensing circuit using an LM35. A previous dissertation I'm continuing on used this circuit:
The output is connected to a DAQ. The sensor correctly detects an increase or decrease in temperature but is not giving correct values. I've compared the temperature values to the temperature readings from a T-type thermocouple and they don't match. Help?
