ESenseSamplingPackage class

The eSense sampling package supporting the following measures:

• dk.cachet.carp.esense.button
• dk.cachet.carp.esense.sensor

Both measure types are continous collection of eSense data from an eSense device, which are:

• Event-based measure.
• Uses the ESenseDevice connected device for data collection.
• No sampling configuration needed.

An example of a study protocol configuration might be:

  // Add a background task that immediately starts collecting eSense button
  // and sensor events from the eSense device.
  protocol.addTriggeredTask(
      ImmediateTrigger(),
      BackgroundTask()
        ..addMeasure(Measure(type: ESenseSamplingPackage.ESENSE_BUTTON))
        ..addMeasure(Measure(type: ESenseSamplingPackage.ESENSE_SENSOR)),
      eSense);

To use this package, register it in the carp_mobile_sensing package using

  SamplingPackageRegistry.register(ESenseSamplingPackage());
