Lots Collected, Little Analyzed

• Collection without analysis has negative ROI

 

Most IoT data are not used currently. For example, only 1 percent of data from an oil rig with 30,000 sensors is examined.

-- McKinsey & Company

 

• As difficult as it is to collect and capture data,
  gaining insights via analysis takes just as much effort

 

• Dependable, real-world on-line analytics take time to develop, tune, and test.

Not a Product Pitch...but

MATLAB: High-level data analytic language and interactive environment for data analysis, visualization, and algorithm development

 

 

Simulink: Block diagram environment for simulation and design. Simulate, generate code, and verify embedded systems

 

 

ThingSpeak: Analytic IoT Platform for storing sensor data and developing IoT applications

• Online analysis and visualization using the MATLAB Language
• Sensor data can be sent to ThingSpeak from any internet capable device using simple REST calls over HTTP or HTTPS.
