New gas concentration sensor for CO2 measurements in high-volume applications available worldwide

Sensirion: The STC31-C is a new gas concentration sensor for measuring high-range CO2 concentrations. It is particularly suitable for high-volume applications in the transportation and storage of perishable and pharmaceutical goods, as well as for breath analyzers for measuring and monitoring CO2 in human breath. The STC31-C is now available globally via our distribution partners.

The new STC31-C gas concentration sensor is based on a revolutionary principle for measuring thermal conductivity and thus offers extremely high repeatability and long-term stability. It is small, measures accurately and reliably, and outputs a digital and fully calibrated signal for gas concentration and temperature. The sensor also impresses with its low power consumption and low cross-sensitivity to humidity and oxygen changes.

The STC31-C is the successor to the proven STC31, but with the addition of a low-cross-sensitivity measurement mode. This mode offers very low cross-sensitivity to changes in humidity and oxygen concentration, enabling measurements of human breath. Otherwise, the STC31-C impresses with the same features as its predecessor and is ideal for measuring high-range CO2 concentrations in high-volume applications.

The outstanding performance of the STC31-C sensor is based on Sensirion’s patented CMOSens® technology, which combines the sensor element and signal processing on a single tiny chip. The proven CMOS technology is ideally suited for demanding and cost-sensitive OEM applications in mass production.

Sensirion also offers an evaluation kit, the SEK-STC31-C, for initial tests and quick and easy evaluation of the sensor.
