What is a CO2 Monitor?

When a carbon dioxide (CO2 Monitor) detector detects too much of this gas, it will trigger an alarm. This could be audible, such as an alert or a beacon, or through data logging and integration into existing building management systems. The data collected can be used to analyse values over time and to alert and resolve specific indoor environmental issues.

This is especially useful in buildings where ventilation rates are reduced to save energy, since CO2 levels can often be missed if not properly monitored. CO2 detectors also help maintain comfortable and healthy indoor climates, as a high level of CO2 indicates that people are breathing enough fresh air.

Choosing the Right CO2 Monitor for Your Home or Business

There are two main categories of carbon dioxide monitoring solutions: portable and fixed monitors. Portable devices are great for checking air quality at regular intervals, while fixed monitors are best for continuous monitoring.

Both types of detectors are based on the same principle, using an NDIR sensor to measure the amount of CO2 present in the ambient air. These sensors are usually quite long-lasting, and are relatively low-cost compared to other monitors. The downside is that they are susceptible to passive drift, which means that over a period of time the sensor can begin to provide skewed measurements.

To combat this, it is important to calibrate the monitor regularly. This is normally done by taking it outside for a few minutes and letting it create a new baseline value based on atmospheric carbon dioxide. This is a very easy process, and it should be carried out in order to ensure that the monitor continues to work as it should.
