I intend to read the output of several LM35 temp sensors connected to the surface beneath solar panels from a cable length of at least 65 meters using an Agilent 34970A DAQ interface. The LM35 puts out 10mVDC/deg. Would it be alright to use a non-inverting opamp circuit to boost the output?
Below is a circuit designed to boost a 0.3 DC input by a factor of 6. It works fine in Multisim but when prototyped on a breadboard, 8.36VDC(pin6-1) is the resulting output instead of the expected 1.8VDC. Any idea why?
Also, I intend to use shielded wire to carry the signals due to its bundled nature. Is this ok?
I would really appreciate your help.
