A carbon monoxide detector or CO detector is a device that detects the presence of the carbon monoxide (CO) gas to prevent carbon monoxide poisoning. CO is a colorless, taste-less and odorless gas produced by incomplete combustion of carbon-containing materials. Elevated levels of CO can be dangerous to humans depending on the amount present and length of exposure. Smaller concentrations can be harmful over longer periods of time while increasing concentrations require diminishing exposure times to be harmful. CO detectors are designed to measure CO levels over time and sound an alarm before danger-ous levels of CO accumulate in an environment, giving people adequate warning to safely ventilate the area or evacuate.
