As our homes get smarter, the sense of digital scent provided by Molecular Property Spectrometer™ (MPS) will improve our health and make us safer. IoT infrastructure companies like NevadaNano develop gas sensing technologies to analyze indoor air in real time to provide accurate, actionable data.

Such data can be used to immediately notify occupants of hazardous situations (such as a natural gas leak), or be integrated into automated, demand-controlled ventilation systems to effectively and efficiently manage air quality—saving lives and energy. The MPS can even serve as a “pre-smoke” detector by warning of a fire at a very early—even pre-fire—stage, based on the presence of vapors produced by overheated materials before combustion even begins.

Most real-time, indoor air quality (IAQ) sensors available today measure and report a generic, composite value, known as the “total Volatile Organic Compounds” (“TVOC”) concentration, present in the air. While useful, such sensors typically suffer from unwanted environmental cross-sensitivity, which can lead to false readings due to fluctuating humidity levels, as one example. More critically, such technologies cannot make a distinction between toxic and non-toxic compounds. The MPS has the power to enable just this type of assessment, in a low-cost, low-power, and reliable platform.

Gas Range
Formaldehyde 0 – 500 ppb
tVOC 0 – 20 ppm

MPS™ IaQ Sensor Features:
