public class HiTechnicBarometer
extends I2CSensor

Hitechnic Barometric sensor
The sensor measures both atmospheric pressure and temperature.

The code for this sensor has not been tested. Please report test results to the leJOS forum.

Supported modes
Mode name	Description	unit(s)	Getter
Pressure	Measures atmospheric pressure	Pascal	getPressureMode()
Temperature	Measures temperature	Degree Celcius	getTemperatureMode()

Sensor configuration
The sensor can be calibrated for pressure using the calibrate method.

Method Detail

init

protected void init()

calibrate

public void calibrate(float pascals)

Re-calibrates the sensor.

Parameters:

pascals - the calibration value in pascals

getCalibrationMetric

public float getCalibrationMetric()

Returns:

the present calibration value in pascals. Will be 0 in case no explicit calibration has been performed.

getPressureMode

public SensorMode getPressureMode()

HiTechnic Barometer, Pressure mode
Measures the atmospheric pressure of the air.

Size and content of the sample
The sample contains one element containing the atmospheric pressure (in Pascal) of the air.

getTemperatureMode

public SensorMode getTemperatureMode()

HiTechnic Barometer, Temperature mode
Measures the temperature of the air.

Size and content of the sample
The sample contains one element containing the air temperature (in degree celcius).
