Among the types of sensors presently used by several manufacturers of smoke detectors are the ionization type, the optic sensor – also called photo electric sensor, the air sampling sensor, and combination type sensors. A smoke detector with an ionization type sensor uses what is called radio isotopes that produce ionization in the air. 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.
