Carbon dioxide (CO2) is not harmful to human body when it is low, but when it overs a certain amount, it will affect the breathing of humans (and other organisms).

The reason is that the concentration of carbonic acid in the blood increases, the acidity increases, and acidosis occurs.

NDIR Sensor CO₂ Monitor adopts NDIR sensor, which can measure concentration of carbon dioxide more accurately.

It's an essential part of a good air quality monitor.
