CO2 sensor

  • Monitoring of room air quality
  • Compact, unobtrusive design
  • Visual indication of concentration
  • Mains plug version similar to Schuko® CEE mains plug
  • With or without EnOcean wireless technology

Reducing the risk of infection by means of CO2 room air monitoring

Studies confirm that CO2 is an indicator for the aerosol concentration. Increased air exchange keeps the CO2 and aerosol pollution in the room low and thus reduces the risk of corona infection. Plug the sensor into the socket and off you go with more security in the office, school or day-care centre: AFRISO CO2 tell you when it is time for ventilation by means of an easily understandable LED traffic light. If the sensor is integrated into the smart home system, ventilation systems can also be controlled or the heating system can be adjusted during ventilation.

For continuous monitoring of the carbon dioxide (CO2) concentration in the ambient air. Application in rooms in which many persons work, study or live and where carbon dioxide levels may consequently be elevated. High concentrations of carbon dioxide in the ambient air reduce the ability of persons to concentrate and perform. Ideal for educational institutions, training/meeting rooms, office areas and household.


CO2 sensor with infrared technology in plastic housing, for connection to a standard CEE socket. The CO2 concentration in the room air is indicated directly at the device by a colour scale:

  • LED green: No ventilation required
  • LED yellow: Ventilation recommended
  • LED red: Ventilation required

The version CO2 sensor F (with EnOcean wireless module) sends the measured values to the AFRISOhome gateway for further processing and initiation of appropriate action. For example, it is possible to start a room ventilation system in order to reduce the CO2 concentration. The current carbon dioxide concentration is also displayed by the app AFRISOhome. The AFRISOhome gateway in conjunction with additional AFRISO smart home products with EnOcean wireless technology allows the user to configure a whole range of fully customisable, extensible applications.
Version CO2 sensor: Version without wireless transmission as stand-alone solution.
