CO₂ Sensor Sensirion STC31 – RAK12008

The RAK12008 CO₂ Sensor, part of the WisBlock Sensor Series, uses the Sensirion STC31 to deliver highly accurate CO₂ measurements even at extreme concentrations. Based on the thermal conductivity principle, it provides reliable readings in the range of 0 to 100 vol%, with an accuracy of 0.5 vol% + 3% (0–25 vol%) and 1 vol% + 3% (0–100 vol%).

Featuring a digital I²C interface, it can be easily integrated with WisBlock Core modules. The sensor also includes a built-in temperature sensor for additional measurement capabilities. Thanks to its compact 10 x 10 mm form factor, the RAK12008 is easy to install even in tight spaces.

Available tutorials and example codes make it easy to get started with high-level CO₂ sensing for IoT solutions.

Typical Applications:

• Monitoring and control of CO₂ levels in industrial processes

• Safety and monitoring systems for enclosed environments

• Agriculture and food production

• Medical and life science applications

• Research and laboratory use
