Voltage API
The Voltage service handles a sensor measuring voltage.
Its type has access to all common capabilities.
Functions
| Function name and parameters | Action | Comment |
|---|
| control(self) | Displays service type graphical interface | Only available using Jupyter notebook |
Variables
| Variable name | Action | Type |
|---|
| volt | Reads or writes voltage in V | read / write: Float |
| threshold | Thresholds voltage variation before filter_changed event trigger. Default value 1.0 V. | read / write: Float |
Events
| Event name | Trigger |
|---|
| changed | Any state modification falling or raising |
| filter_changed | Voltage variation bigger than threshold |
