AirSens®, intelligent air quality sensors

IAQ, versatility & control

AirSens range is the first IAQ sensor designed and produced by ventilation experts. The perfect solution for Demand Control Ventilation systems. 

Indoor Air Quality (IAQ)

We spend most of our time indoors, at the same time energy efficiency requirements have improved thermal insulation in buildings.

For this reason, ventilation has a fundamental role in improving indoor air quality. A good IAQ level improves productivity, health, well-being and comfort for its occupants.

AirSens offers three different versions in which the control element can be carbon dioxide (CO2), volatile organic compounds (VOC) or relative humidity (RH).

  • AIRSENS-RH-off.png
  • AIRSENS-VOC-off.png


Three different sensors, three different references:
  • AirSens CO2: Recommended for open areas where occupancy can be variable during the day. Humans generate CO2 between inhalation and exhalation. 
  • Airsens VOC: This versatile version reacts to sporadic changes to the accumulation of substance-derived odours; Volatile Organic Compounds such as alcohols, aldehydes, ketones and organic acids.
  • AirSens RH: Sensor that recognizes the relative humidity inside an area, therefore, recommended for places where this is variable or tends to be concentrated excessively.
