The K30 10% (100,000 ppm) CO2 sensor (formerly known as SE-0118) is a high performance CO2 sensor used commonly in scientific, medical, and biological applications. It is an accurate, low-cost solution for OEMs products like CO2 safety alarms or leak detectors.


  • Built on tested K30 Sensor platform
  • Simple to install, pre-calibrated and ready-to-use
  • Proven reliability, low cost
  • Flexible analog and digital outputs


  • 030-7-0007 - K30 10% CO2 Sensor - For integration into high-volume OEM products.
  • 030-7-0007-C - K30 10% CO2 Sensor with Custom Outputs -  Customize analog or digital outputs for your application. After ordering, email or fax the Custom Outputs PDF form under the Documents tab and we will custom-configure your sensor’s settings. If the form is not received, your sensor will be delivered with the default specifications.
  • CM-0049 - K30 CO2 Sensor Development Kit - Easy to use, simply plug the sensor module into your PC via USB. Use our free GasLab® software to measure and graph carbon dioxide in real time or for data logging.
  • CM-200 - Sensor Development Kit - Easy to use, simply plug the sensor into the PCB and plug it into your PC via USB. Use our free GasLab® software to measure and graph carbon dioxide or use our library of source code on Github to build your own application or for OEM batch testing/configuration. Order sensors on this page, then order the Devkit here.

We recommend that all first-time users purchase either the CM-0049 or CM-200 Development Kit for fastest and easiest results.

Great product and support!

Thanks to the provided PDF documents with detailed instructions on how to connect the sensor to an Arduino UNO board, and the example script files demonstrating communication with the sensor, it was very easy to read-out the measured CO2 values. (My tech skills are limited.)

Henry Fong

We are evaluating the sensor and have no further comment at this moment.

"Easy to install, easy to set up, and easy calibration - just what I was looking for."
