Measurement class
The result of a measurement of data of a given dataType at a specific point or interval in time. When sensorEndTime is set, the data pertains to an interval in time; otherwise, a point in time.
The unit of sensorStartTime and sensorEndTime is either determined by the sensor that collected the data, or, in case the sensor does not provide this information, by the phone. For example, the timestamps could be a simple clock increment since the device powered up. Note that in CARP we prefer microseconds over milliseconds for higher precision.

Create a new measurement based on
data. - Measurement.fromData(Data data, [int? sensorStartTime])
-
Create a measurement from
databased on thesensorStartTimeprovided by the sensor. IfsensorStartTimeis not specified, the phones current time stamp as microseconds since epoch is used.factory -
