Sensors

SEM stands for SEnsor Module. It collects data from sensors (listed below) from Communication Units and makes them available for internal usage to other SCALAR modules (internal API), and external usage to integrators (external API).
Sensor data is provided in a non-aggregated way. Sensor module’s intention is to be used by other modules as a source of truth about sensor data.

In some cases, sensor data is used for reporting (historical); in other cases, the latest value for a sensor might be requested; and in some other cases. Sensor module also provides raw sensor data to customers and/or integrators in form of Feed/bulk.

The following table includes a list of sensors that is used by events:
