Any reason why cyberware versions of sensors (olfacroty bootser, blabla) are so much more expensive and have so much more availability than non-cyber sensors? Although both perform exactly the same popurse (in the case of the olfactory booster its even mentioned in the book) and both are of equal size.

Connectivity must also be the same, as every sensor ist ,just as everything else, wireless.

BEcause making something you can stick inside someone's head is harder than making something you can stick into a machine?

Im talking mostly about the versions that are installed in cyberlimbs

The olfactory booster (cyberware) adds its rating to smell based perception tests. The olfactory scanner (sensor) provides its rating as dice for a small based perception test.

That's the way it should work.

So the non-cyberversion in wifi-mode connected to the user can not be used to add dice for a smell test?

That's my understanding too.
