Remember if the raw data was already converted to calibrated pressure.

Member Function Documentation

void Data::calculateCalibratedHumidity ( )
inlineprotected

See calculateCalibratedTemperature()

void Data::calculateCalibratedPressure ( )
inlineprotected

See calculateCalibratedTemperature()

void Data::calculateCalibratedTemperature ( )
inlineprotected

Use the calibration data read from the sensor to calculate the calibrated temperature from the raw data. The result is stored in this struct for further access. Implemented differently for Fixed Point, Single and Double Precision by template specialsation.

int32_t Data::getPressure ( )
inline

Get the calibrated pressure from the device in Pascal.

If recalculation is necessary it is done on the fly. No I2C transaction.

int32_t Data::getTemperature ( )
inline

Get the calibrated temperature for the device in 0.01 degree Celsius

If recalculation is necessary it is done on the fly. No I2C transaction.
