AbstractA scan of commercial off-the-shelf (COTS) sensors is provided for three indoor pollutants (formaldehyde, volatile organic compounds and radon) based on the information from the literature and manufacturers obtained between July 2008 and February 2009. The performance requirements for sensors are also proposed for a meaningful operation in sensor network systems aimed for ventilation and indoor air quality (V&IAQ) controls. Several COTS sensors meeting the proposed requirements are identified for formaldehyde and radon in this report. The identified formaldehyde COTS detectors have a resolution of 5 to 10 ppb, a detection range of 0 to 1 ppm, and a response time of a few to 30 minutes, and are priced between CDN $1,000 and $7,000. Several real-time continuous radon sensors also meet the pre-defined performance requirements, including a detection range between 20 and 5,000 Bq/m3, a resolution of 10 Bq/m3, and a response time of 2 days, and are priced between CDN $300 and $1,100. No commercial volatile organic compound (VOC) sensors meet the established requirements for VOCs. Several of the identified formaldehyde COTS sensors will be validated in NRC?s labs for their actual sensitivity and selectivity.
