Smoke alarm can sense water vapor?
Smoke alarm is based on trace radioactive elements in the smoke molecules in the ionization of the principle of the current to work.
Smoke alarm is the density of the solid particles in the air to determine the alarm ... smoke is solid particles, water vapor is liquid droplets so it will not sense
Smoke detectors are classified as point-type ion smoke detectors, point-type photoelectric smoke detectors and infrared beam "laser" linear smoke detectors. They are on the natural material burning particles to a certain concentration after the alarm, the cooking is generally not alarm, but its allowed working environment: relative humidity less than 90%, the temperature minus 10 degrees to 50 degrees, when your room temperature and humidity than these , May cause a breakdown, may also cause inexplicable reported fire. So, you still use less, for the best time to open the window, may be better.
