The STCC4 is Sensirion’s next generation miniature CO2 sensor for indoor air quality applications. Based on the

thermal conductivity sensing principle and Sensirion’s CMOSens® technology, the STCC4 enables monitoring

of CO2 gas concentration in ambient indoor air conditions at an unmatched cost-effectiveness and form factor.

SMD assembly as well as tape & reel packaging allows cost- and space-effective integration of the STCC4 for

high-volume applications. The STCC4 is 100% factory-calibrated and enables automatic on-board

compensation of the CO2 output for humidity and temperature through an external SHT4x sensor.
