1-Wire carbon dioxide sensor TSG200

TSG200 is a 1-Wire carbon dioxide sensor with 10000ppm working range and IP30 protection.

Not recommended for new projects.

Will be discontinued soon.



TSG200 is a precise 1-Wire carbon dioxide sensor.

For carbon dioxide concentration measurements, advanced NonDispersive InfraRed (NDIR) element is used. It detects carbon dioxide in a gaseous environment by its characteristic absorption.

The signal from NDIR element further is digital signal processed by a microcontroller. This provides a fully calibrated digital output.

The 1-Wire carbon dioxide sensor supplies precise measurement and stable performance. It can be used to measure a wide variety of CO₂ concentrations in public areas, offices, and industries.

The sensor uses 1-Wire interface for communication. Only one TCG200 can be connected to the 1-Wire bus, but several another sensors can be connected too. This allows multi-parameter monitoring with a single controller.


  • Broad dynamic range (0-10000 ppm) for variety of CO2 concentrations;
  • Calibration on fresh air;
  • Resolution as high as 10 ppm;
  • IP30 ingress protection;
  • Excellent long-term stability;
  • Each device has a unique 64-bit serial number.


  • Monitoring of air parameters in mushroom plants and greenhouses;
  • Environmental quality monitoring and assessment;
  • Control and monitoring of chemical processes;
  • HVAC environmental controls;
  • Building’s management systems (BMS);
  • Laboratories for cellular respiration of yeast.

The sensor can be used with
