React has two different approaches to dealing with form inputs. A photoelectric, or optical smoke detector, contains a source of infrared, visible, or ultraviolet light typically an incandescent light bulb or light-emitting diode (LED) a lens, and a photoelectric receiver typically a photodiode.In spot-type detectors, all of these components are arranged inside a chamber where air, which may contain smoke from a nearby fire, flows.
