AppliedSensor Indoor Air Quality Module Detects Odors and VOCs in Commercial Facilities, Office Buildings, Classrooms and Homes

Warren, New Jersey – May 20, 2008 – To address growing concern about the effects of poor indoor air quality, AppliedSensor, a provider of chemical sensor components and modules, has developed the IAQ-100 Indoor Air Quality Module. A sensitive, low-cost solution for detecting poor air quality caused by volatile organic compounds (VOCs) such as cooking odors, bio-effluence and outdoor pollutants, the IAQ-100 can be integrated into any demand-controlled ventilation environment, including commercial facilities, offices, classrooms, kitchens, and bathrooms.

In classrooms, the air quality can affect students' health, their ability to learn, and the productivity of the teaching staff. Professor David Wyon, International Centre for Indoor Environment and Energy, Technical University of Denmark, said, "It has now been shown beyond reasonable doubt that poor indoor air quality in buildings can decrease productivity as high as six to nine percent."

"Odors are the pollutants found most objectionable by a room's occupants," said Tom Aiken, AppliedSensor Director of Marketing and Business Development. "Carbon dioxide sensors cannot respond to changes in air quality caused by odors. Our IAQ-100 module is highly sensitive to odors and other volatile organic compounds. Plus, it's compact and energy efficient, making it the ideal solution for any clean air initiative."

The IAQ-100 is equipped with a sensor element based on micro-machined metal oxide semiconductor (MOS) technology. A change of resistance in the presence of reducing gases such as CO and VOCs generates a signal that is translated into specific air quality levels and linked to specific gas concentration ranges. When the threshold of air quality levels for target gases is exceeded, the module can signal a climate control system to increase air flow by turning on a fan, opening a window, or emitting an odor-masking fragrance. When referenced against traditional CO2 sensors, the IAQ-100 module provides direct, consistent and reliable correlation to CO2 levels.
