CO2 Gas Sensor User Manual – Vernier

The Vernier CO 2 Gas Sensor measures gaseous carbon dioxide levels by monitoring the amount of infrared radiation absorbed by carbon dioxide molecules.. The sensor has two ranges: Low (0–10,000 ppm) and High (0–100,000 ppm). Students can use the CO 2 Gas Sensor to measure the change in carbon dioxide levels for a variety of systems, including. A chamber containing small living things such ...

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 measures the amount of IR light that ...

Gas detection in refrigeration systems

IR Infrared Infrared technology utilises the fact that most gases have a characteristic absorption band in the infrared region of the spectrum, and this can be used to detect them. Comparison with a reference beam allows the concentration to be determined. Even though they are relatively expensive in comparison to other sensor…

CO2 Sensors Products |

Indoor and outdoor air has between 400ppm and 2,000ppm CO2 by volume. This means that for projects from measuring indoor air quality to measuring atmospheric CO2, a 01% (010,000ppm) CO2 sensor is your best solution. For applications like CO2 alarms in restaurants, breweries, or around stored CO2 tanks, a 5% CO2 sensor …
