| Implement to provide critical class sensor thresholds. Objects implementing |
| Sensor.Threshold.Critical must be instantiated in the correct hierarchy within |
| the sensors namespace. The following sensor hierarchies are recognized: |
| temperature |
| fan_tach |
| voltage |
| altitude |
| current |
| power |
| energy |
| |
| Additionally, any object implementing Sensor.Threshold.Critical must also |
| implement Sensor.Value. |
| |
| properties: |
| - name: CriticalHigh |
| type: double |
| default: NaN |
| description: > |
| The upper bound of the critical threshold. A value of 'NaN' is used |
| to indicate there is no threshold of this type. |
| - name: CriticalLow |
| type: double |
| default: NaN |
| description: > |
| The lower bound of the critical threshold. A value of 'NaN' is used |
| to indicate there is no threshold of this type. |
| - name: CriticalAlarmHigh |
| type: boolean |
| description: > |
| True if the sensor value has exceeded the defined bound. |
| False if the sensor value has not exceeded the defined bound. |
| |
| CriticalAlarmHigh may be set to False to clear an alarm condition. |
| The behavior of setting CriticalAlarmHigh to True is undefined. |
| - name: CriticalAlarmLow |
| type: boolean |
| description: > |
| True if the sensor value has exceeded the defined bound. |
| False if the sensor value has not exceeded the defined bound. |
| |
| CriticalAlarmLow may be set to False to clear an alarm condition. |
| The behavior of setting CriticalAlarmLow to True is undefined. |
