STC42A-D-R5

STC42A Hydrogen Thermal Conductivity Sensor

Sensirion STC42A Hydrogen Thermal Conductivity Sensor is designed for applications that require reliable hydrogen concentration measurements in clean air. The STC42A uses the thermal-conductivity measurement principle, resulting in superior repeatability and long-term stability. It features an I²C controller interface for autonomous humidity compensation from a corresponding humidity-temperature sensor (SHT41A-AD1B). QFN and tape and reel packaging offer cost- and space-effective integration of the STC42A for high-volume production. Sensirion’s CMOSens^® sensor technology enables the outstanding performance of the STC42A by integrating the signal processing, sensor element, and digital calibration on a single CMOS chip.
