Mouser Now Shipping Sensirion STCC4 Miniature CO2 Sensor for Smart Environmental Applications
August 21, 2025 – Mouser Electronics, Inc., the authorized global distributor with the newest electronic components and industrial automation products, is now shipping the new STCC4 miniature CO2 sensor from Sensirion. The STCC4 provides direct measurement of CO2 in an ultra-small 4 × 3 × 1.2 mm3 package for indoor air quality monitors, air conditioners, smart thermostats, and other space-constrained environmental monitoring applications.
The Sensirion STCC4 CO2 sensor, available from Mouser, features thermal conductivity sensing technology, low current consumption, and an I2C interface for seamless integration into compact electronic devices. Utilizing the latest technological advancements, the STCC4 provides the accuracy needed for indoor air quality applications with both accurate signal compensation and monitoring of relevant environmental parameters when combined with Sensirion temperature and humidity sensors. The STCC4 miniature CO2 sensor has an SMD design optimized for high-volume assembly and tape-and-reel packaging.
Mouser also offers the Sensirion SEK-STCC4 evaluation kit, available to order, which features an integrated development board to evaluate the STCC4 CO2 sensor. This evaluation kit includes an adapter cable, a jumper wire set, and an STCC4 development board. The SEK-STCC4 evaluation kit requires a Sensirion Sensor SEK-SensorBridge to connect the bridge with the STCC4 sensor ports to develop sensor applications with proprietary plug-and-play hardware through a personal computer. The combined products enable downloadable viewer software to evaluate sensors that measure humidity, temperature, gas, and carbon dioxide.
