Project Description

Short Description

TSG200 is a precision carbon dioxide gas sensor. It utilizes 1-Wire interface for communication. The device utilizes advanced NonDispersive InfraRed (NDIR) element. It detects carbon dioxide in a gaseous environment by its characteristic absorption. The signal form NDIR element further is digital signal processed from a microcontroller, thus provide fully calibrated digital output. The used 1-Wire (registered trademark of Maxim Integrated Products, Inc.) communication interface allows to connect several sensors over a short wiring.

The carbon dioxide gas sensor supplies precise measurement and stable performance. It can be used to measure a wide variety of CO₂ concentrations in public areas and offices, mushroom farms, wineries, terrariums, chemical reaction rooms, greenhouse etc.

TSG200 is supported by TCW220 and TCW241.

  • Broad dynamic range (0-10000 ppm) to measure a wide variety of CO2 concentrations;
  • Calibration on fresh air;
  • Excellent long term stability;
  • Resolution as high as 10 ppm;
  • Unique 64-Bit serial number for multiply sensors support.

  • Control and monitoring of chemical processes;
  • Monitoring of air parameters in mushroom plants
  • Monitoring of air quality in offices and public areas;
  • Building’s management systems (BMS);
  • Laboratories for cellular respiration of yeast.
