The CM1107N NDIR Dual Channel CO2 Sensor is designed to monitor and detect carbon dioxide levels in indoor air quality applications and demand control ventilation environments for commercial and residential areas.

This dual beam (single light source, dual channel) CO2 sensor, based on non-dispersive infrared (NDIR) technology can detect CO2 concentration of indoor air. With higher accuracy, superior long term stability, it is widely used for ventilation systems, air purifiers, air conditioners, intelligent agriculture, food storage and cold-chain.


  • Advanced non-dispersive infrared technology
  • High Accuracy, temperature calibration within whole measurement range
  • Maintenance Free - Automatic Baseline Calibration (ABC)
  • Temperature and humidity compensation throughout the entire measurement range
  • Small, compact structure
  • Long lifespan - 10+ years


  • Indoor Air Quality (IAQ)
  • HVAC controller
  • Central Air Conditioning
  • Modified Atmosphere Packaging (MAP)
  • Agriculture


  • CM1107N - CO2 Sensor Module- dual channel, high accuracy NDIR sensor designed to monitor carbon dioxide levels.
  • 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 both this sensor and the CM-200 Development Kit for fastest and easiest results.
