Carbon is a new generation connected carbon dioxide detector that also comes with ambient temperature and relative humidity sensors.  

Carbon is not only a simple CO2 sensor. Thanks to its edge computing architecture and IZIAIR embedded algorithm, Carbon calculates an indoor air quality index to help you take the appropriate actions.  

Carbon is also a physical, connected push button that you can choose to program with two different actions (short or long-press) and intuitive light feedback.    

It is an ideal product for connected homes, residential buildings and public-access buildings (schools, nurseries, hospitals, children's centers, retirement homes, etc.).      

Product benefits: 

  • 3-in-1 Carbon Dioxide detector, Indoor Air Quality monitor and Push Button 
  • IZIAIR Indoor Air Quality Index 
  • Wireless sensor for easy and fast installation 
  • Up to 10-year battery life for the product and wireless connection 
  • Elegantly designed detector that blends in with any decor    

Applications : 

  • Indoor air quality control in residential premises and public places 
  • HVAC control · Maintenance optimization 
  • Enhancement of building energy efficiency 
  • Development of new services: home care, home support, well-being, heating cost savings, etc.
