The answer to 'difference between smoke detector' is that smoke detectors and carbon monoxide (CO) detectors are both important safety devices for the home, but they serve different purposes. Smoke detectors are designed to detect the presence of smoke, which is a sign of a fire, while CO detectors are used to detect the presence of carbon monoxide, an odorless and colorless gas that can be deadly.
Smoke detectors are typically installed on the ceiling or high on the walls of each room in a home, and they use either ionization or photoelectric sensors to detect smoke particles in the air. When smoke is detected, the detector will sound an alarm to alert the occupants of a potential fire. CO detectors, on the other hand, are often installed near bedrooms or in other areas where CO gas may accumulate, such as near furnaces or water heaters. These detectors use electrochemical sensors to detect the presence of CO and will also sound an alarm when levels become dangerous.
