This CO2 detector solution uses Renesas’ RTD120D dual thermopile to detect the ambient CO2 concentration. It has a Non-Dispersive Infrared (NDIR) thermopile-based gas sensing circuit, and the concentration of CO2 gas is measured based on the intensity of the NDIR radiation.

System Benefits​:

  • High accuracy gas concentration measurements
  • True CO2 measurement, not eCO2
  • Compact design
  • Datalogging of all measurements
  • Wireless connectivity

Target Applications:

  • True CO2 level detection
    • Capnography
    • HVAC/Air quality monitoring
    • Safety/Mining
    • Process control/gas analysis
