Minimal size. Maximize the potential: Sensirion launches revolutionary miniature CO₂ sensor

The STCC4 enables mass-market CO₂ monitoring in a wide range of applications with unmatched form factor, cost efficiency and low current consumption. Sensirion is excited to launch the latest addition to their CO₂ sensor portfolio in the last quarter of 2024.

Stäfa, Switzerland – STCC4, one of the world's smallest sensors for direct CO₂ measurement, unlocks vast new applications for monitoring CO₂ previously limited by size and cost constraints. Designed for seamless integration into compact electronic devices, the sensor is a groundbreaking newcomer in the CO₂ sensor market.

Utilizing the latest technological advancements in thermal conductivity sensing, the STCC4 provides the accuracy needed for indoor air quality applications at a low current consumption. Both accurate signal compensation and monitoring of relevant indoor environmental parameters are achieved when STCC4 is combined with Sensirion’s industry-leading temperature and humidity sensors. Engineered and manufactured in Switzerland, it has been optimized for easy integration into high volume applications through its SMD design and tape & reel packaging. The STCC4 is suitable for a wide range of applications, including indoor air quality monitors, smart thermostats, air conditioners and much more.

“CO₂ monitoring is essential to ensuring comfortable indoor environments. We believe that the size and cost efficiency of STCC4 will empower healthy air wherever people work or live,” says Dr. Kaitlin Howell, Product Manager for CO₂ sensors at Sensirion.
