Detailed Description

Buffers sensor samples and forwards them to an IDataSaver at a controlled rate.

Note

When to use: wrap any sensor stream that needs to be saved at a limited frequency to avoid overwhelming the saver or consuming excess storage.

Constructor & Destructor Documentation

SensorDataHandler()

SensorDataHandler::SensorDataHandler	(	uint8_t	name,
		IDataSaver *	dataSaver )

Construct a handler for a specific sensor.

Parameters

name	8-bit identifier for the sensor/channel.
dataSaver	Destination used when saving samples.

Note

When to use: create one per sensor source and share a saver across multiple handlers as needed.

Definition at line 6 of file SensorDataHandler.cpp.

Member Function Documentation

addData()

int SensorDataHandler::addData

(

DataPoint

data

)

Ingest a data point and persist it if the save interval elapsed.

Parameters

data	Data point to record.

Returns

Status from the underlying saver.

Note

When to use: on every new reading; rate limiting is handled internally.

getLastDataPointSaved()

DataPoint SensorDataHandler::getLastDataPointSaved ( ) const

Definition at line 53 of file SensorDataHandler.h.

getName()

uint8_t SensorDataHandler::getName ( ) const

inline

Definition at line 51 of file SensorDataHandler.h.

restrictSaveSpeed()

void SensorDataHandler::restrictSaveSpeed

(

uint16_t

interval_ms

)

Set the minimum gap between persisted samples.

Parameters

interval_ms

Minimum milliseconds between writes.

Note

When to use: tune logging cadence to balance fidelity vs. storage.
