Smoke detectors can be undoubtedly sensitive occasionally.
Depending on the style and brand you get, just about anything will set them off, and it gets to be a real pain! I have this undoubtedly issue with my smoke detector, and the thing that sets it off all the time is my central heating, ventilation as well as A/C, but you see, the air vents are right by the smoke detector, and anytime the central heating, ventilation as well as A/C method pops on, if it comes on with a lot of force, the smoke detector goes off! It does not matter if it is heating or cooling, the smoke detector can not tell the difference, and believes there is a fire going on.
It got to the point 1 time where I had to remove the smoke detector from the hallway where it was, because I wasn’t able to get any great sleep. It was literally going off if the heating or air conditioning even blew a cut hour of any kind of air out of the air vents, the solution to this was to transfer the smoke detector and mount it in an area of the beach house where there was no air vents from the central HVAC method unit. It was quite hard, because my beach house has undoubtedly superb air flow, and there are air vents nearly all over the place. I did find a spot for the smoke detector, and that was in this 1 small corner in the residing room, and right above where the front window is, there is no air vent there to blast it with heating or cooling from the central HVAC system.
