How do smoke detectors work and more specifically why does steam set them off

249 viewsEngineeringOther

We had what seemed to be an overly sensitive smoke detector that would even go off when boiling water. Got sick of it and bought a new one that said on the packaging that it didn’t respond to steam. Sounded great except that a week later we discovered it didn’t respond to smoke either (burnt some cooking, lots of smoke) checked the battery, all that, it should have gone off with the smoke.

The YouTube channel “Technology Connections” has an excellent video on the matter.
