Detailed Description

Discovers and samples DS18B20-compatible sensors on a OneWire bus.

The class performs discovery, starts conversions, and later collects results once the conversion time for the selected resolution has elapsed. This avoids blocking the controller loop while still keeping tracked sensor roles stable.

Constructor & Destructor Documentation

SensorManager()

SensorManager::SensorManager ( const SensorManagerConfig &  config )

explicit

Creates a sensor manager for the supplied OneWire configuration.

Parameters

config

Bus pin, sampling interval, resolution, and tracked sensors.

Member Function Documentation

begin()

bool SensorManager::begin

(

uint32_t

nowMs

)

Initializes the bus, discovers sensors, and requests the first conversion.

Parameters

nowMs

Current monotonic timestamp in milliseconds.

Returns

True when bus initialization completed.

formatTrackedAddress()

void SensorManager::formatTrackedAddress	(	size_t	trackedIndex,
		char *	buffer,
		size_t	bufferSize
	)		const

Formats a tracked sensor ROM code as a hexadecimal string.

Parameters

trackedIndex	Index into the tracked sensor array.
buffer	Destination character buffer.
bufferSize	Size of the destination buffer in bytes.

snapshot()

const SensorSnapshot & SensorManager::snapshot

(

)

const

Returns the latest sensor snapshot.

Returns

Immutable snapshot reference.

update()

void SensorManager::update

(

uint32_t

nowMs

)

Advances discovery and temperature conversion state.

Call this frequently from the main loop. It will request a new conversion when the sample interval elapses and will finish pending conversions once the DS18B20 conversion time has passed.

Parameters

nowMs

Current monotonic timestamp in milliseconds.
