First off, I know enough about electronics to get hurt. Second, talk down to me .. I don't mind. I get lost in the jargon.
Here's my situation:
I'm using a pressure sensor using 5-12volts input and .008 to .050mV output. The output is going to an Arduino Uno analog. The problem (and you probably already see this coming) is that the analog in on the Arduino requires 0-5VDC.
I have two hurdles to get over:
1) I need to amplify the .050mV to 5V.
2) I need to connect that output to the Arduino. (one leg to the analog in is obvious, but the other is not at all clear)
What I've tried:
LM741 OP-AMP but, apparently the mV input to the OP-AMP is too low.
Your help would greatly be appreciated.
