AirSens IAQ Sensor

The AirSens® range is the first IAQ sensors designed and produced by ventilation experts.

AirSens Indoor Air Quality Sensor

The perfect solution for Demand Control Ventilation systems.

We spend the majority of our time indoors so it is important that the air inside is clean, fresh and pollutant-free. By introducing energy-saving measures to improve thermal comfort, we have sealed up our homes and workplaces, restricting the flow of air, which can lead to stale, humid environments filled with a host of contaminants. 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® is available in 3 different versions:

  • AirSens® CO2 to control Carbon Dioxide (CO2)
  • AirSens® VOC to control Volatile Organic Compounds (VOC)
  • Airsens® RH to control Relative Humidity (RH)

3 Sensors For 3 Different Jobs

AirSens® CO2

AirSens® CO2
Recommended for homes and workplaces with variable occupancy levels during the day.



AirSens® VOC

AirSens® VOC
Reacts to sporadic changes in the accumulation of substance-derived odours: Volatile Organic Compounds such as alcohols, aldehydes, ketones and organic acids.


AirSens® RH


AirSens® RH
Recommended for homes and workplaces where relative humidity may vary or be particularly excessive.


A Unique Patented Design

The AirSens® IAQ range offers a unique patented design allowing it to easily blend into its surroundings in different environments. The front LED indicator lets you know at any moment the IAQ level of the air indoors.

Flexibility of Use

The AirSens® sensor runs from a universal power supply and is compatible with both AC & EC ventilation units.

The indoor air quality sensor has three operating modes including a relay (on/off or min/max), 0-10V and 2-10V. AirSens® also offers remote reading and editing of all Modbus map parameters using a Building Management System (BMS).
