Sunrise HVAC

Senseair Sunrise HVAC is our next version of our new generation NDIR sensor with Optical Solid State design. Electronics with no moving parts makes this sensor robust and resistant to vibrations. Any application with a tough environment or in environments with explosion risk is benefited by the solid state design. 

It is the first NDIR sensor with LED technology that truly saves power while maintaining a high precision. 


  • Optical solid state
  • Ultra Low Power
  • High precision
  • Robust
  • Mass production
  • Self-calibrating


The ultra low power consumption makes Sunrise optimal for battery and wireless applications.

The sensor has an accuracy (CO2) ±30 ppm ±3% of reading. Thanks to the built-in self-correcting algorithm you can mount and forget your sensor for the next 15 years and it will still be accurate.
