The CO2 data logger solution bundle includes our flexible GS1 data logger and an industrial CO2 remote probe that attaches to the logging device via a 3 meter cable. This is a great way to get started with carbon dioxide monitoring for homes, offices and more.

The primary reason people monitor carbon dioxide is to identify poor indoor ventilation. This is important for things like reducing the risk of COVID-19 infections and improving sleep quality. Other reasons to monitor CO2 include identifying respiratory conditions, the impact on cognitive performance and more.

Understanding Indoor Air Quality: The Importance of a CO2 Data Logger

For consumer-grade monitors, it’s best to look for one that uses NDIR sensors. These sensors are very accurate and tend to last a long time. However, they are susceptible to a phenomenon called sensor drift that causes the sensor to provide skewed measurements over time. To counteract this, you should choose a monitor that allows for manual recalibration.

Most of the monitors on this list also feature temperature and relative humidity sensors. These aren’t necessary, but they can help provide a more complete picture of your air quality. For example, a monitor that measures a CO2 level as well as air temperature and relative humidity will be able to tell you if a room is too hot or if it needs more ventilation.

Lastly, be sure to consider how often you’ll need to read your CO2 data logger. Some monitors will send a continuous stream of readings to your smartphone, while others only log a few times per day and then upload that data to a cloud-based system.
