STCC4-D-R3

STCC4 Miniature CO2 Sensor

Sensirion STCC4 Miniature CO₂ Sensor provides direct measurement of CO₂ in an ultra-small package size of 4mm x 3mm x 1.2mm (L x W x H). This device is ideal for applications previously limited by size and cost constraints and offers seamless integration into compact electronic devices. The fully factory-calibrated STCC4 sensor features thermal conductivity sensing technology, low current consumption, and an I²C interface. Both accurate signal compensation and monitoring of relevant indoor environmental parameters are achieved when the module is 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. The STCC4 sensor is suitable for a wide range of applications, including indoor air quality monitors, air conditioners, smart thermostats, and much more.
