Sensirion STC31-C-R3 CO2 Concentration Sensor 0-100%, I2C Output

The Sensirion STC31-C-R3 CO2 Concentration Sensor 0-100%, I2C Output is a high-precision thermal conductivity sensor designed to measure CO₂ concentrations from 0–100 vol% in air or nitrogen. With I²C output, individual factory calibration, and support for forced or self-calibration, it ensures excellent accuracy in varied environments. It supports low-noise and low-cross-sensitivity modes and compensates for environmental conditions using external temperature, humidity, and pressure data. Compact and efficient, it is ideal for medical, industrial, or environmental monitoring.

Note: Refer to datasheet in the ATTACHMENTS section for more info. regd. the product. the product is STC31 and further marking may varry as per product avalability.
