This records the specific sensor type (for example, temperature, humidity, or voltage) tied to a logged status event on the Opengear monitoring unit, distinguishing it from the general device-type classification stored separately in this table. Administrators use it to understand precisely what physical quantity the reported status value corresponds to when reviewing the sensor event log. For instance, a value of "Humidity" indicates the associated status value for this event should be interpreted as a humidity percentage rather than a temperature.
