Sensor Classes - Sensors are objects that monitor other objects for changes and invoke callbacks when changes occur.

## NAME

coin\_sensors - Sensor Classes

 \- Sensors are objects that monitor other objects for changes and invoke callbacks when changes occur.

## SYNOPSIS

### Classes

class **SoAlarmSensor**\
 The **SoAlarmSensor** class is a sensor which will trigger once at a specified time.  class **SoDataSensor**\
 The **SoDataSensor** class is the abstract base class for sensors monitoring changes in a scene graph.  class **SoDelayQueueSensor**\
 The **SoDelayQueueSensor** class is the abstract base class for priority scheduled sensors.  class **SoFieldSensor**\
 The **SoFieldSensor** class detects changes to a field.  class **SoIdleSensor**\
 The **SoIdleSensor** class is a sensor which will trigger as soon as the application is idle.  class **SoNodeSensor**\
 The **SoNodeSensor** class detects changes to nodes.  class **SoOneShotSensor**\
 The **SoOneShotSensor** class is a sensor which will trigger once.  class **SoPathSensor**\
 The **SoPathSensor** class detects changes to paths.  class **SoSensor**\
 The **SoSensor** class is the abstract base class for all sensors.  class **SoSensorManager**\
 The **SoSensorManager** class handles the sensor queues.  class **SoTimerQueueSensor**\
 The **SoTimerQueueSensor** class is the abstract base class for sensors triggering on certain timer events.  class **SoTimerSensor**\
 The **SoTimerSensor** class is a sensor which will trigger at given intervals.

## Detailed Description
