The Cubic CM1107N Dual Beam IR 5,000ppm CO2 sensor module is designed to monitor and detect carbon dioxide levels using state of the art dual-beam NDIR technology at an incredibly low price. Simply add 5VDC power and a UART signal reader like Termite to monitor CO2 levels from your PC.

Dual beam NDIR technology makes this sensor perfect for applications like greenhouse growing or auto garages that are not regularly exposed to ambient air. Instead, it uses a 2nd reference detector that is continuously compared to the actual detector to compensate for long-term CO2 level drift.


  • Advanced non-dispersive infrared technology (NDIR) 
  • High accuracy within the entire measurement range
  • Dual-beam compensates for sensor drift
  • Automatic or manual calibration
  • Small, compact design


  • Agricultural Greenhouse Growing
