Note: getCompRH is the preferred function below (passing true to cause a measurement cycle). If actual values used for the compensated ready are necessary, use the getHumidity(false) and getTemperature(false) functions following the getCompRH call. Also note the sensor should not perform more than a couple of measurements per second to limit the heating of the sensor.",
