The CM1106SL-N and CM1106-SL-NS Super Low Power NDIR CO2 Sensors are designed for wide use in battery-powered and wireless indoor applications where the need for continuous measurement mode is used.

These NDIR CO2 sensors are ideal for indoor air quality applications such as demand control ventilation, HVAC and commercial/residential environments.

Both pinned and non-pin versions are available depending on your application. Note that the non-pinned version includes I2C output.


  • NDIR technology with intellectual property
  • Super low power consumption
  • Adjustable Automatic Background Calibration cycle
  • Temperature calibration throughout the whole measurement range
  • Wide supply voltage range enabling battery options
  • Maintenance free - Automatic Baseline Calibration (ABC)
  • Temperature and Humidity Compensation Throughout the Entire Measurement Range
  • Long life span (15+ years) 
  • Small, Compact structure, easy to install


  • IAQ (Indoor Air Quality)
  • Ventilation Systems
  • Air Purification
  • HVAC
  • DCV (Demand Control Ventilation)
  • Automotive


  • CM1106SL-N Super Low Power NDIR CO2 Sensor - single channel sensor, good accuracy, NDIR super low power, UART output only, with pins.
  • CM1106SL-NS Low Power NDIR CO2 Sensor -  single channel sensor, good accuracy, NDIR super low power, UART and I2C communications, without pins.
  • 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. Note: pinned sensors may require minor pin clipping.

We recommend that all first time users purchase both this sensor and the CM-200 Development Kit for fastest and easiest results.
