That's kinda weird, why doesn't some enterprising person start cranking t=
hem
out and sell them for $300-$400 apiece?=0D

Anyway, if we're talking thousands, then I guess I'll have to look closer=
at
DIY-WB.=0D

The DIY-WB project provides a buffered output and doesn't require a displ=
ay
built in...=0D
any thing you buy pre-built will be several GRAND... you can build the
DIY-WB yourself for about 200 including the WB-O2... Autozone has the NT=

sensor for 169 in the bosh brand (an NTK sensor in the Bosch box) it's fo=

A little off from the original question, but is there a ready source for =
a=20
plug and play" WB-O2 that gives the 0-5V output as described below? I've
seen lots of discussion about DIY-WB and such, but I'd rather pay the ext=
ra
cash and get going more quickly with my project. I'm looking for voltage
level output, not a display or anything like that.=0D

a narrow band O2 is what is in 99.9% of the cars on the road... it is a
non-linear sensor with an output of 0-1 volt... 0v being lean, 1v being r=
ich
=2E. at stoich, it produces approx 0.450V output, but going rich makes t=
he
output swing rapidly up and going lean makes it swing rapidly down .=0D
=0D
a wideband O2 (At least the NGK/NTK I am familiar with) is actually a nar=
row
band sense element and an Oxygen Ion pump in a single package... it take=
s a
special controller to run... the controller looks at the O2 sensing elem=
ent
output, and if it varies from stoich (0.450V) the controller drives the
Oxygen ion pump... if it's rich, it pumps Oxygen ions into the sample
chamber until Stoich is reached, then the controller knows exactly what t=
he
mix was due to how much Oxygen it needed to add... conversly, if it's lea=
n
(less than 0.450V) on the sensor, then the Oxygen Ion pump is commanded t=
o
remove Oxygen from the sample until 0.450V is again reached... the outpu=
t
of the controller is a linear 0-5V signal and is 2.50V at stoich.=0D

Could someone please explain Wide Band/Narrow Band O2 Sensors. I am tryin=
