Can a Carbon Monoxide Detector Detect Carbon Dioxide ...

+

A carbon monoxide detector cannot detect carbon dioxide. In general, a carbon monoxide detector uses an electrochemical sensor that outputs electric current proportional to the amount of carbon monoxide the chemicals are exposed to. A carbon dioxide detector uses a nondispersive infrared (NDIR) sensor that measures light in a sample of air.
