We are lucky to develop sensors in Delsbo.
Fresh air, forests, lakes, and CO₂ levels that regularly fall back towards the outdoor baseline.
But many indoor environments do not work like that.
Hospitals, nursing homes, control rooms and other 24/7 occupied buildings do not reliably return to a fresh-air baseline. In those applications, automatic background calibration cannot be used as the main stability mechanism.
That is the engineering problem behind Senseair Dual Technology.
An integrated solid-state reference detector, built into the LED source chip, gives the sensor a more direct way to monitor light source behaviour over time. Shorter disturbance chain. Stronger foundation for long-term CO₂ measurement stability.
Developed in Delsbo, for environments where the baseline cannot be taken for granted.
We have written more about the technology, the application and the thinking behind Senseair Dual Technology in this article.
