Hello to everybody,
thanks to accept me on this forum.
I'm 36 years old and I am from Italy (Sicily, very close to Etna Voltano).
I'd a Jeep Cherokee XJ 4.0 Limited 1989 AW4 all stock.
I want to share with you my small project.
It's a O2 sensor meter (0V-5V wide range) using an LM3914 integrated circuit.
Here the youtube video when the O2 works in Closed Loop mode:
Attached you can find also the project schematic (if you want to do the same).
My conclusion:
0V = RICH
2.5V = RIGHT
5V = LEAN
When works in closed loop, the signal oscillates from 0V to 5V.
Regards,
Lucio - aka etnaskynet
