LabVIEW 2009 VIs and Sample Programs for the Barometric Sensor

Tuesday, August 30th, 2011

Announcing LabVIEW 2009 support for the new HiTechnic Barometric Sensor!  Use these VIs to get temperature, atmospheric pressure, and altitude in your LabVIEW programs.  The main read VI gives you these pieces of data in both imperial and metric units.  There are also support VIs to calibrate the sensor and to calculate altitude pressure, the pressure at sea-level.  Sample programs include a LabVIEW version of the Altimeter program, similar to the NXT-G version already released, that displays an airplane style altimeter.

Altimeter Gauge using the new Barometric Sensor

Wednesday, July 27th, 2011

The new HiTechnic Barometric Sensor can be used to measure altitude since air pressure varies with altitude.  The NXT-G block for this sensor includes actions to read altitude as well as to adjust the altitude base pressure and to set the altitude pressure using a known altitude.  The NXT-G programs presented in this blog post shown an airplane style altimeter on the NXT screen.  Like a real altimeter, the altitude pressure can be adjusted to account for different meteorological conditions.
