safety  why


Question by  wmcginnes (1)

Why does my smoke detector go off when I open my bathroom door after showering?

It's steam, not smoke.

The "detector" part uses an optical sensor, which goes off when blocked by the smoke. The steam causes condensation on the sensor, and causes the same effect. If you fan it with a paper plate or something similar, it will clear it and shut it off.
