I'm pretty sure they detect flammable gas, like Methane, cat farts & etc.

I just got my supply of small bottles together to move to storage out of the house.
Found a little gizmo I can use to clean out that old leftover 20 pound tank.
1 lb propane bottle refill adapter
It can be used to refill the empties.
