Just to clarify this comment. When tanks get low, the additive (Ethyl-Mercaptan) that gives propane its odor can be come concentrated and you could smell that and potentially set off your propane detector. Ethyl-mercaptan is an oil, and old propane tanks tend to build up that oil. As you get to the bottom of the tank you're probably getting a much higher concentration of that oil in with your propane. That's a different situation than carbon monoxide which is a product of combustion.
Obviously smelling the additive requires you to investigate but typically a low tank situation is what I look at first. If there is any possibility, I shut off the low tank and switch to the full tank. If the odor goes away, you probably dealing with the low tank issue. Also typically the smell will be strong at the site of a burning flame.
