Smoke detector is a fire-fighting device that must be installed in public places such as hotels. The principle is that the infrared beam of the infrared emission tube is scattered by smoke particles, and the intensity of the scattered light is directly proportional to the concentration of smoke, so the intensity of the infrared beam received by the photosensitive tube will change, and it will be converted into an electrical signal and eventually into an alarm signal.

Smoke detectors are suitable for places where there is a lot of smoke when there is a fire, but there is no smoke under normal circumstances, such as restaurants, hotels, teaching buildings, office buildings, computer rooms, communication rooms, stacks and archives rooms and other industrial and civil buildings.
