    • readCalibrationData

      public void readCalibrationData() throws RuntimeIOException
      This method reads the calibration data common for the Temperature sensor and Barometer sensor included in the BMP180
      Throws:
      RuntimeIOException - if an I/O error occurs

    • getTemperature

      public float getTemperature() throws RuntimeIOException
      Method for reading the temperature. Remember the sensor will provide us with raw data, and we need to transform in some analysed value to make sense. All the calculations are normally provided by the manufacturer. In our case we use the calibration data collected at construction time.
      Specified by:
      getTemperature in interface ThermometerInterface
      Returns:
      Temperature in Celsius as a double
      Throws:
      RuntimeIOException - If there is an IO error reading the sensor

    • getPressure

      public float getPressure() throws RuntimeIOException
      Read the barometric pressure (in hPa) from the device.
      Specified by:
      getPressure in interface BarometerInterface
      Returns:
      Pressure measurement in hPa
      Throws:
      RuntimeIOException - if an IO error occurs

    • close
