SensorObject

A sensor attached to any object except bodies (connectors, constraint, spring-damper, etc). As a difference to other SensorBody, the connector sensor measures quantities without a local position. The sensor measures OutputVariable and outputs values into a file, showing per line [time, sensorValue[0], sensorValue[1], …]. Use SensorUserFunction to modify sensor results (e.g., transforming to other coordinates) and writing to file.

The item SensorObject with type = ‘Object’ has the following parameters:

• name [type = String, default = ‘’]:

  sensor’s unique name
• objectNumber [type = ObjectIndex, default = invalid (-1)]:

  object (e.g. connector) number to which sensor is attached to
• writeToFile [type = Bool, default = True]:

  True: write sensor output to file; flag is ignored (interpreted as False), if fileName=’’
• fileName [type = String, default = ‘’]:

  directory and file name for sensor file output; default: empty string generates sensor + sensorNumber + outputVariableType; directory will be created if it does not exist
• outputVariableType [type = OutputVariableType, default = OutputVariableType::_None]:

  OutputVariableType for sensor
• storeInternal [type = Bool, default = False]:

  true: store sensor data in memory (faster, but may consume large amounts of memory); false: internal storage not available
• visualization [type = VSensorObject]:

  parameters for visualization of item

The item VSensorObject has the following parameters:

• show [type = Bool, default = True]:

  set true, if item is shown in visualization and false if it is not shown; sensors can be shown at the position assiciated with the object - note that in some cases, there might be no such position (e.g. data object)!
