9V Long Life Time Fire Detector

An optical smoke detector, also called a photoelectric smoke alarm, is a type of smoke detector that uses optical light to detect the presence of smoke. These devices contain a light emitter, which may be optical, infrared, or ultraviolet light, as well as a light sensor. If smoke crosses the light beam, the intensity of the light that hits the sensor will be reduced, triggering the alarm.
