A smoke detector is a device that detects the presence of smoke in an environment, typically as a fire safety measure. It triggers an alarm to alert people of potential fire hazards. Smoke detectors are commonly found in homes, buildings, and other areas to warn occupants of smoke or fire before it becomes too dangerous.
There are two main types of smoke detectors:
1. Ionization Smoke Detectors: These detect fast, flaming fires by using a small amount of radioactive material to ionize the air inside the detector. When smoke particles enter the chamber, they disrupt the ionization process, triggering the alarm.
2. Photoelectric Smoke Detectors: These use a light sensor and a light source to detect smoke. When smoke enters the chamber, it scatters the light, triggering
