I'd like to offset a variable voltage by 1 volt. What I have is an LM34 temperature sensor that outputs a linear voltage based on temperature (+10mV/F). I'd like to change that to (+10mV/F - 1V). What's the easiest way to drop the LM34's output by 1V?
I tried a potentiometer but my understanding is that a pot is a divider so it doesn't give me the result I'm looking for. I also tried a diode that was supposed to have a 1V drop but that didn't seem to work either (not sure why). Is there a simple solution?
Thanks, Ray
