Mouser Electronics, Inc. now offers the new STCC4 miniature CO2 sensor from Sensirion. The device provides direct measurement of CO2 in an ultra-small 4mm × 3mm × 1.2mm3 package for indoor air quality monitors, air conditioners, smart thermostats, and other space-constrained environmental monitoring applications.
The CO2 sensor features thermal conductivity sensing technology, low current consumption, and an I2C interface for seamless integration into compact electronic devices. Utilising the latest technological advancements, the device provides the accuracy needed for indoor air quality applications with accurate signal compensation and monitoring of relevant environmental parameters when combined with the company’s temperature and humidity sensors. The miniature CO2 sensor has an SMD design optimised for high-volume assembly and tape-and-reel packaging.
The company 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 to the STCC4 sensor ports, enabling the development of sensor applications with proprietary plug-and-play hardware through a personal computer. The combined products allow downloadable viewer software to evaluate sensors that measure humidity, temperature, gas, and carbon dioxide.
