Figure 25. SensorCloud Data View

Settings

- The settings view provides options for adding meta-data, configuring the data

displays for each channel, creating alerts based on data thresholds, setting the data time

zone, and more.

MathEngine

®

- is used to analyze sensor data. Functions include the ability to filter out

frequencies, smooth out noisy data, perform math operations such as Fast Fourier Transforms

(FFTs), and more. MathEngine

®

interfaces with the SensorCloud graphing view for faster

processing. Users can write their own algorithms for custom applications. Refer to the
