详细描述
The QHumidityReading class holds readings from the humidity sensor.
QHumidityReading Units
The humidity sensor returns the relative humidity as a percentage, and absolute humidity in grams per cubic meter (g/m3). Note that some sensors may not support absolute humidity, 0 will be returned in this case.
属性
absoluteHumidity : const qreal
Absolute humidity Measured in grams per cubic meter. Note that some sensors may not support absolute humidity.
访问函数:
| qreal | absoluteHumidity() const |
relativeHumidity : const qreal
Relative humidity Returned as a percentage.
访问函数:
| qreal | relativeHumidity() const |
成员函数
void QHumidityReading::setAbsoluteHumidity(qreal value)
Sets absoluteHumidity to value.
参见 absoluteHumidity().
void QHumidityReading::setRelativeHumidity(qreal humidity)
Sets relativeHumidity to humidity.
参见 relativeHumidity().
