Detailed Description

Sensirion flow-meter I2C client: SF06 (SFM4300 data sheet §4) and SFx6000 (SFM6000D, SFC6xxx/SFM6xxx I2C interface reference v1.1).

Start/stop continuous measurement per gas or binary mixture, single-frame read, concentration update, scale/offset/unit query, product identifier and general-call soft reset on both families; averaging and sleep on SF06; temperature through the output-buffer pointer on SFx6000. The family is learned from the product identifier (or given by the caller) and decides which start code means which gas. Every received 16-bit word is CRC-8 checked; every argument word is sent with its CRC-8.

Typical session:

sfm::Driver<MyI2c> dev(i2c, sfm::addr::kSfm4300Default);
auto id = dev.ReadProductIdentifier();          // idle mode only
dev.ConfigureAveraging(0);                      // idle only: average-until-read
dev.StartContinuous(sfm::Gas::CO2);             // reads scaling first
auto m = dev.ReadMeasurement();                 // every ≥0.5 ms
