typedef void(* YCarbonDioxideValueCallback) (YCarbonDioxide *func, const string &functionValue) |
Retrieves a CO2 sensor for a given identifier. The identifier can be specified using several formats:
-
FunctionLogicalName
-
ModuleSerialNumber.FunctionIdentifier
-
ModuleSerialNumber.FunctionLogicalName
-
ModuleLogicalName.FunctionIdentifier
-
ModuleLogicalName.FunctionLogicalName
This function does not require that the CO2 sensor is online at the time it is invoked. The returned object is nevertheless valid. Use the method YCarbonDioxide.isOnline() to test if the CO2 sensor is indeed online at a given time. In case of ambiguity when looking for a CO2 sensor by logical name, no error is notified: the first instance found is returned. The search is performed first by hardware name, then by logical name.
If a call to this object's is_online() method returns FALSE although you are certain that the matching device is plugged, make sure that you did call registerHub() at application initialization time.
- Parameters
-
func | : a string that uniquely characterizes the CO2 sensor |
- Returns
- a YCarbonDioxide object allowing you to drive the CO2 sensor.
