An Intelligent Home-Based Sensing System for Indoor Air Quality Analytics


Executive Summary


AirSense provides homeowners with a tool to monitor and mitigate indoor air pollutants. This intelligent indoor air quality (IAQ) monitoring and analytics system works with air quality sensors to automatically detect pollution, identify its sources, determine its risk level and provide actionable suggestions to improve air quality.


Description of Technology


Existing IAQ monitors focus on measurement and data visualization but do not empower users to address indoor air pollution in real-time. A research team from MSU has filled this critical gap with AirSense. This new technology extracts data from sensors, analyzes it and uploads it to a cloud server. Once the pollution sources are identified the technology predicts the contamination level in the near future with a non-parametric regression scheme. Finally, through a smartphone application, AirSense provides immediate appropriate actions to minimize the user’s pollution exposure. It also can deliver IAQ profiling reports to help users better understand how their household activities impact air quality.


Key Benefits

  • Identifies the pollution source
  • Provides simple immediate solutions
  • Tracks the level of indoor air pollution
  • Educates consumers on their IAQ



  • Homes and apartments
  • People sensitive to air quality (eg. asthmatics, allergy suffers, children)
  • Public buildings and office environments
