A detectors that senses abnormal amount of Carbon Monoxide in the surrounding area.

A carbon monoxide detector is a device that detects the presence of the toxic gas carbon monoxide, a colorless and odorless compound produced by incomplete combustion and lethal at high levels. Early designs were basically a white or beige element which would fade to a brownish or blackish color if carbon monoxide were present. As carbon monoxide (CO) related deaths rose during the 1990s, audible alarms became the norm.
