A smoke detector is a device designed to detect smoke, which is the main sign of a fire. When it is detected, the detector sends an alarm signal, which helps to warn people about the fire and allows you to take measures to extinguish the fire or evacuate.

Smoke detectors can be self-contained, battery-powered, or they can be part of a centralized fire alarm system. In stand-alone models, when triggered, an audible signal is given on the spot. In system models, the detector can transmit a signal to the fire control panel.

Such devices are important for early detection of fire, especially in residential and public buildings, which reduces the risk of loss of life and property.
