The T6613 CO2 sensor module is one of the most successful OEM CO2 sensors ever made, with millions in use worldwide. It is most commonly found in commercial and residential wall-mounted CO2 transmitters for demand-controlled ventilation (DCV).

The T6613 is a single wavelength NDIR sensor. It continuously monitors the environment and records the lowest values, then uses automatic background calibration (ABC) logic to offset the sensor’s stored calibration. This means the sensor is best used in applications where the environment periodically drops to ambient (~400ppm) CO2 levels.

Both ambient air (AMP-0001) and sampling sensor (AMP-0005) variations are available.


  • Affordable gas sensing solution for OEMs
  • Reliable sensor based on years of engineering and manufacturing expertise
  • Flexible platform designed to interact with other microprocessor devices
  • Eliminates the need for calibration when ABC Logic is used
  • Altitude compensation can be added if altitude is known
