The process is quite technical, but what this type of detector contains is ionized air molecules in a chamber inside the device. The ionized air carries electrical current and maintains that current, until something disrupts the air molecules. When the air molecules are disrupted, usually by smoke, the current drops, and an electrical circuit sound the alarm. Ionization smoke detectors are said to be cheaper to manufacture, but the downside is that they are prone to false alarms. They sound the alarm at the slightest degree of disruption in the ionized air, even from ordinary smoke in the kitchen.
Types Of Smoke DetectorPhotoelectric smoke detectors or optical smoke detectors They are
