Namespace Sensus

Classes

Datum

A single unit of sensed information returned by a probe.

Provides information on the alive status of the app. Will be submitted to the RemoteDataStore on an interval specified by HEALTH_TEST_DELAY. The RemoteDataStore should contain a sequence of heartbeats with Timestamp values according to this interval. For example, if the interval is 6 hours, then there should be a sequence of 4 HeartbeatDatum readings in the RemoteDataStore each day.

ImpreciseDatum

Represents a Datum that could be imprecisely measured.

Logger

LoggingLevel

Logging levels.

ParticipationReportDatum

Provides participation rates on a per-Probe basis. For example, for a PollingProbe set to poll 10 times per day with a ParticipationHorizon of 10 days, we would expect to see 100 pollings at full participation. If the device only records 67 pollings, then the participation rate would be 67%. The definition of participation rate is different for ListeningProbes, which are designed to be running continuously. Here, participation is defined to be the fraction of the ParticipationHorizon (e.g., 10 days) for which the ListeningProbe was turned on.

A Protocol defines a plan for collecting (via Probes), anonymizing (via Anonymizers), and storing (via LocalDataStores and RemoteDataStores) data from a device. Study organizers use Sensus to configure the study's Protocol. Study participants use Sensus to load a Protocol and enroll in the study. All of this happens within the Sensus app.
