S1 Pro CO₂ Add-on

The built-in air quality sensor estimates CO₂ levels by analyzing changes in the surrounding air. This provides useful insight into overall trends, but it remains an approximation. The dedicated CO₂ sensor measures carbon dioxide directly, delivering true CO₂ readings with higher accuracy and long-term stability.

Ideal for spaces where ventilation, occupancy, and health matter, and where decisions rely on precise, trustworthy data.
