New Sensor for Measuring High CO2 Concentration Announced

Nov 04 2020 Read 310 Times

Sensirion is proud to announce that the new STC31 CO2 sensor for measuring high CO2 concentrations is now available globally through Sensirion’s distribution network.

The STC31 is a chip-sized gas concentration sensor for high range, accurate CO2 measurements designed for high-volume applications. The sensor is based on a revolutionised thermal conductivity measurement principle, which results in superior repeatability and long-term stability. This makes the STC31 the perfect choice for applications such as cold chain logistics where reliability is key. By relying on the thermal conductivity technology, the sensor offers an ultra-low power consumption, even compared to low-power optical sensors. This makes it the ideal choice for battery-operated applications, delivering top performance at an absolute minimal power budget.

The sensor features a digital I2C interface, which makes it easy to connect directly to a microprocessor. The accuracy is 0.5 vol%. and ±3% of measured value and the response time is faster than 1 second. The outstanding performance of these sensors is based on Sensirion’s patented CMOSens® Technology, which combines the sensor element, signal processing and digital calibration on a small CMOS chip. The well-proven CMOSens® Technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications.

“Due to its ultra-low power consumption, ease of integration and unmatched price-performance-ratio the STC31 will enable many new applications when it comes to measure high CO2 concentrations,” said Johannes Goedejohann, Product Manager at Sensirion.
