Sensirion AG

The most effective way to measure high CO2 concentrations

The Top 3 Advantages
1

Robust and no drift over lifetime, ultra-low power consumption

2

On-chip humidity compensation

3

Small chip-sized package (3.5x3x1 mm) and fully calibrated digital output with I2C interface

The ideal choice for high-quality mass production and cost-sensitive OEM applications

The STC31 is a chip-sized CO2 gas concentration sensor covering the complete concentration range. The sensor is based on a revolutionized thermal conductivity measurement principle, which results in superior repeatability and long-term stability. This makes the STC31 the perfect choice for applications where reliability is key. Thermal conductivity technology has an ultra-low power consumption, even compared to low-power optical sensor allowing for battery operated applications by delivering top-performance.

The sensor features a digital I2C interface, which makes it easy to connect directly to a microprocessor. 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 CMOS® Technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications.
