Every year, smartphones and tablets embed 9 billion sensors, all representing potential data sources.
In 2014, there were 49 million [source: IHS] environment-related sensors (humidity, gas air quality, particulate air quality, UV, barometers, etc.). The number of gas sensors alone will reach 375 million in 2020.
In addition, their monetary value is growing rapidly: +6.7% per year from 2014–2019 [source: Technavio] will amount to almost $20 billion in 2019.
