Air quality and CO2 sensors

DPWQ* - DPPQ*
  • General characteristics

    CO2 and VOC (volatile organic compound) air quality sensors are used to measure and monitor the concentration of CO2 and VOC in air-conditioned commercial and residential environments.

    These provide the controller a proportional signal to manage activation of the outside air intake fans when necessary, thus making building climate control more efficient and ensuring better air quality for occupants (e.g. in shopping centres, shops, theatres and offices).

    The CO2 sensor uses NDIR (Non-Dispersive Infrared) technology and detects concentrations of gas deriving from human respiration.

    The VOC sensor detects a number of air pollutants, such as: carbon monoxide, hydrogen sulphide, solvent and alkane vapours, cigarette smoke, car exhaust, air expelled by human respiration, combustion smoke from wood, paper and plastic.
