Optical Smoke Detectors: Enhancing Fire Safety Through Light An optical smoke detector , also known as a photoelectric smoke alarm, is a type of smoke detector that uses optical light to detect the presence of smoke. In the world of fire safety, optical smoke detectors play a crucial role in safeguarding lives and property. How Optical Smoke Detector Works? Inside the detector, a light source, often an LED, emits a beam of light into a sensing chamber. In the absence of smoke, this light beam travels undisturbed to a photodetector, typically a photodiode. When smoke enters the chamber, it scatters the light particles, causing some of the light to strike the photodetector. This interruption triggers the alarm, alerting inhabitants to the presence of smoke and potential fire. Application areas of Smoke Detectors Smoke alarms find critical applications in various settings to enhance safety. In residential spaces, they are a primary defense against home fires, providing early detectio...
