REVELTRONICS

Hello,

I'm willing to retrieve signal from o2 sensor on my car but I understand I need a controller to get 0-5V voltage.



Can you advise a simple cheap controller?

Thanks

For AFR you will need wideband o2 sensor. Standard o2 sensor only will give you information about lean/reach mixture. Black wire is 0-1V signal as I remember.

If you sure that it's wideband o2 sensor, then controller will be required. But controller depends on type of O2 sensor. E.g. for BOSCH LSU 4.9 I recommend Innovate LC-2, but it can be any controller with 0-5V output.

hi guys, what do you think about this one?

Not tested it and can't find datasheet/manual on site. Does it have 0-5V AFR output?

Hi mate, and sorry for late reply, its but hard to get the information! Here is the connection diagram

On schema is "0-5V OUTPUT" to display - the same output will work with UTCOMP AdcX input but you will need to know also scaling (how 0-5V output is scaled to AFR value in your controller)
