How does an NDIR CO2 Sensor Work? |

Like every IR gas sensor, the analyzer at Mauna Loa used the same basic principle for measuring CO2. It has an infrared light radiation source at one end of a gas sample tube and an IR detector at the other. The band of infrared radiation is very close to the absorption band of CO2. As a result, the amount of light radiation that is absorbed by the CO2 molecules is proportional to the amount ...

Low Volt IR Co2 Sensors and Diving -

25/03/2008· Just curious, I was looking at Co2 Sensors, and I ran across several IR measuring Co2 Sensors with less then 1 sec response times, like this ICX Photonics manufactures IR gas sensors and emitters for Industrial Safety, IAQ and HVAC applications. and was wondering why something like this couldn't be used in rebreathers? They suck low power (35mW), and either return ppm or %.

Senseair CO2 Sensor Pressure Dependence |

Senseair CO2 Sensor Pressure Dependence. August 05, 2015. All infrared (NDIR) CO2 sensors have a dependence on pressure. This is because of the physics principle used to measure CO2 concentration. The NDIR type of sensor measures the IR radiation absorbed by CO2 molecules, which corresponds to the mole concentration.
