Smoke sensors, also known as smoke detectors, are critical safety devices designed to detect the presence of smoke in environments. They are typically used in homes, offices, and other buildings to provide early warning of potential fires. When smoke is detected, the sensors trigger alarms, alerting occupants to the presence of smoke and allowing them to take prompt action to evacuate or mitigate the fire. Smoke sensors are often interconnected to provide comprehensive coverage throughout a building and can be powered by batteries or connected to the electrical system. These sensors are essential for fire safety, providing valuable time to respond and potentially save lives and property.
