XENSIV™ PAS CO2 gas sensors for CO2 detection

Measure what matters with XENSIV™ PAS CO2 sensors

Compact and highly accurate photoacoustic spectroscopy (PAS)-based carbon dioxide sensors for precise CO2 detection

XENSIV™ CO2 environmental sensor for CO2 detection

The XENSIV™ PAS CO2 sensor measures indoor CO2 across many applications. Reliable readings help create safer, more comfortable spaces.

In smart homes and buildings, it enables real-time monitoring for demand-controlled ventilation, air purifiers, and thermostats. This improves air quality and energy efficiency. Built for integration: use it in CO2 detector designs or IoT CO2 sensors, tie it into building controls as a CO2 sensor in HVAC, and support CO2 leak monitoring where required.
