The K30 10,000ppm CO2 Sensor Module (030-8-0006) is an industry favorite known for its low-cost, accuracy, long life and low maintenance. It is used in hundreds of HVAC and IAQ products and applications. In addition, this CO2 sensor is easy to program with several output options to meet virtually any OEM project specifications.


  • Ideal for residential, commercial, HVAC or IAQ applications
  • Simple to install, pre-calibrated and ready-to-use
  • 2 analogue outputs, 2 digital outputs
  • Proven reliability, low cost, maintenance free


  • K30 CO2 Sensor (030-8-0006) - for integration into high-volume OEM products.
  • K30 CO2 Sensor with Custom Outputs (030-8-0006-C) - Customize analog or digital outputs for your application. After ordering, email or fax the Custom Outputs PDF form and we will pre-configure your sensor’s settings. If the form is not received, your sensor will be delivered with default settings.
  • K30 CO2 Sensor Development Kit (CM-0024) - 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.
  • Sensor Development Kit (CM-200) - 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-0024 or CM-200 Development Kit for fastest and easiest results.

WOW! You don't know you need it until you have it

I am a retired chemist and live in a retirement community. Covid shut down a restaurant and even before the virus the air was so-so. Now I can measure the PPM of CO2 anywhere. The closed restaurant was terrible, but my calibration of outside air was 410PPM! Our committee now has evidence to back our arguments. I even verified the General Services tech's statement that our hall was set to input 100% outside air. It is even thought it is not cooled. At least it is fresh. Thank you CO2meter. Jerry

CO2 Sensor & Software

Sensor & Software worked great. A bit of a learning curve. Suggestions: You might want to inform your clients which sensors read just CO2 and not temp. or humidity. The CM-0024 just reads CO2. Also, the COM drivers was a bit difficult, but achievable. Finally, you might want to rethink your SCR-0039 screws. Finding a screw driver to fit the head was very difficult and the self tapping was so tight, it could possibly damage the sensor.
