Hi,
I've been asked to build a relatively simple AFR gauge for a car, fitted with a standard narrow-band O2 sensor. I realise this is the electronics forums, and I already have the electronics sorted, just wondering if anyone has done this before....I can't 'view' the signal I'm supposed to be measuring, With it being 'narrow band' its not exactly accurate, but the guy wants an led bargraph, judging by the voltage curve for the sensor I tihnk its just going to oscillate back and forth . Any experiences/info regarding this sort of sensor would be useful....if it varies that much, I was thinking of integrating it as a way of getting better resoultion.

I might be able to squeeze resolution out of it (0.9-1v) but I'd just thought I'd check here in case people have designed/built such a gauge. Sorry if this is an odd quesiton.
