Internet of Things

  • Approximately 4.9 billion connected devices in use in 2015
  • 1 in 5 developers now work on IoT projects
  • ~19 million developers worldwide, ~19% are doing IoT related-work, up 2% from last year

    • Examples of increased Efforts

    • Connected Kitchens - Gartner projects sensors in devices that could result in 15% savings in the food and beverage industry by in the next 5 years.

      • Where is the Real Money in the IoT?

      • Services that pull and house the data!
      • IoT standards are in flux, some very complex, but there will always be data
      • Gartner projects IoT will add $1.9 trillion in value to businesses
      • Vertical integration of sensors with business services will dominate IoT

        • AoT or Analytics of Things

        Connecting inanimate objects and sensors to the Internet is only the first step. The term AoT points to the fact that IoT devices generate a lot of data that must then be analyzed to be useful.

        • Pattern recognition - identifying patterns and developing statistical models that explain variations
        • Anomaly detection - identifying situations that are outside of defined boundaries, such as a temperature that is too high or the presence of an individual in an area that should be uninhabited
        • Predictive asset maintenance - detecting potential problems in machinery before they occur
        • Optimization - optimizing automated processes, such as cutting logs at a lumber mill or calibrating machinery in a factory
        • Prescription - recommending the best course of action for a given situation, often for front-line workers, as when weather and soil sensing is used for "prescriptive planting" by farmers
        • Situational awareness - piecing together seemingly disconnected events and explaining them, as when a series of oil temperature readings in a car, combined with dropping fuel efficiency, indicate it's time for an "oil change"

          • Parts List

          1. Arduino Uno: $24.95
          2. Protoshield: $15.00
          3. RTC (Real Time Clock): $6.99
