Note that both sensor principles allow lowcost sensor solutions, at least for markets with high volumes. Even taking into account the advanced electronics and data processing that are necessary to achieve high sensitivity, selectivity, and stability, high performance sensor systems can be realized for well below €, as has been demonstrated for fire detection [ 16 ].
The TVOC concept is used as a practical time and costeffective method of surveying indoor environments for contamination. Global consensus has resulted in the emergence of guidelines for TVOC standards of indoor air quality (IAQ) issued by governmental organizations in different countries ( Australia, Finland, Germany, Hong Kong, Japan). Recommended TVOC levels of IAQ that are …
By measuring the total volatile organic compounds (TVOC) and applying it to a rating scale, these sensors provide the necessary information that allow connected systems to address clean air in the ambient environment. The sensor chips are typically just a few millimeters in width, and can easily fit within the existing electronics of exhaust fans, air filtration systems, and HVAC systems.

Aeroqual offers two types of VOC measurement sensors; Photoionization Detector (PID), and Gas Sensitive Semiconductor (GSS). Both sensor types are nonselective which means they can be used for measuring a wide variety of VOCs. To achieve this they have been calibrated against isobutylene that allows them to respond to a wide range of VOCs at varying degrees of sensitivity. Each type has a calibrated measurement range against a set of VOCs. PID type VOC sensors …
