What Does a Carbon Monoxide Detector Do and How Does it ...

20210812· Once the carbon monoxide detector alarm sounds, it must be in a carbon monoxidefree environment to silence the siren. When will my carbon monoxide detector go off? The CO alarm sounds if your sensor detects a buildup of carbon monoxide in your home—usually before you start sensing symptoms. With a low CO level (50 ppm), it may take up to eight hours for the alarm to go off. Higher …

How does an NDIR CO2 Sensor Work? |

NDIR is an industry term for "nondispersive infrared", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector. The IR light detector …

Infrared Carbon Dioxide Sensors

Calibration of infrared carbon dioxide sensors. The sensor requires a twopoint calibration. First, the carbon dioxide sensor must be zeroed. This is performed by flowing a gas without carbon dioxide through the analyzer and adjusting the zero on the analyzer. Second, the span needs to be adjusted. A span gas containing an amount of carbon ...
