    Carbon Dioxide (CO2) Sensor Modules

Telaire Internal CO2 Sensor for Automotive Applications

The Telaire T6743 Internal CO2 Sensor is a nondispersive infrared (NDIR) CO2 sensor that implements a single channel diffusion sampling method for automotive HVAC applications, including automatic fresh air control and safety sensing for CO2 refrigerants.

Along with the patented ABC Logic™ lifetime calibration warranty, its low power consumption, compact design and simple product integration, make this an affordable gas sensing solution. All units are factory-calibrated to measure CO2 concentration levels up to 5,000 ppm.

 

  • For safety - Measure and control in-cabin CO2 levels to prevent driver drowsiness.
  • For energy savings - Reduce variations in heating and cooling in-cabin through demand control ventilation.

Specifications

ABC Logic Automatic Background Calibration – The algorithm that uses ambient air concentrations to adjust the sensor and compensate sensor long-term drift.
Adjustment cycle period is 12 – 192 hours of operation in active mode. Practical adjustment cycle depends on operating conditions.
Measurement Range Air Quality Control: 400 – 5,000 ppm CO2
Safety Alarm for Air Quality Control and CO2: 400 – 40,000 ppm CO2
Output Range 0 – 65,000 ppm CO2
Measurement Period Active Mode: 5 seconds
Low Power Mode: 5 minutes
Sleep Mode: 12 hours
Timing of these modes can be configured per customer requirements.
Resolution and Repeatability Internal Sensor Resolution: 1 ppm
Repeatability: 30 ppm at 1000 ppm (Typical)
Accuracy in Active Mode Range: 400 ppm to 5,000 ppm
±200 ppm or 10% of the reading, whichever is greater @ 0 to 50°C
Range: 5,000 ppm to 40,000 ppm (4%)
10% of the reading @ 0 to 50°C
Temperature Dependence Additional 0.5% of reading per °C or 5 PPM/C, whichever is greater outside the range 0 to 50°C
Pressure Dependence 0.135% of the reading per mm Hg
Response Time (90% of Step Change) Active Mode: <40 seconds, dependent on test regime (Typical)
Warm-Up Time First measurements in:
< 5 sec after power-up
< 2 minutes maximum accuracy in Active Mode
Total Lifetime 130,000 hours, limited by microcontroller flash retention specification
Operational Lifetime In Active Mode: 45,000 hours
Relative Humidity 0-95% non-condensing
