A data source is a producer or consumer of data in the TelemetryJet CLI. A microcontroller running the TelemetryJet Arduino SDK is a single data source. You may receive data from one or more data sources.
A dimension is a single series of data, identified by a unique string name that you provide.
A data point is a single sample connected to a dimension. A data point contains a dimension ID, timestamp in milliseconds, and a value. TelemetryJet supports data of multiple types.
