Find the nearest mirror and look at the space between and below your eyes. All kidding aside what kind of odor? Airborne chemical sensors detect very specific chemical compounds, "universal" olfactory sensors don't exist.
Ok, this is probably a long-shot, but don't the utility companies add a rotting meat smell to natural gas (since it is odorless on its own)? Maybe a sensor that detects gas leaks will be useful to you.
Ok, I said it was a long-shot.

I vaguely remember hearing somewhere that the majority of foul smelling odors have one or more sulfur atoms somewhere in the molecule, I dont know if this is the case with bacterial decomposition, but it may be worth investigating.

Odor sensors, probably more complex than desired.
Find chemicals and gases produced by the condition, there are numerous specialized sensors out there that can be read into a processor

Mercaptan is an odorant that smells like rotten eggs. It is added to natural gas as a safety measure to allow natural gas to be easily detected.
Here's a link that sells some common gas sensors:
