Photoelectric smoke detectors have a small beam of light inside the chamber, which can be interrupted by smoke particles. This electrical current is different from the one that's generated by the batteries powering your smoke detector, so it won't turn off if your room gets too smoky. Ionization smoke detectors will start blaring when particles fill their chamber and block the small electrical current that's being generated between two plates inside the smoke detector. Neither is better than the other, so don't worry about getting 'the wrong kind of smoke detector.' National Institute of Standards and Technology, smoke detectors can be broken down into two categories: ionization detectors and photoelectric detectors, each of which has a specific trigger that sets off their alarm.
