The Barometer can be used to measure and monitor atmospheric pressure. It works well for conducting weather studies or experiments that involve pressures close to normal atmospheric pressure. It can also be used as an altimeter if you have a portable interface.

Hurricane Rita

While preparing to evacuate the Chinquapin School in Highlands, Texas (just east of Houston), physics teacher Brian Lamore had the presence of mind to recognize a unique data-collection opportunity. Brian set up a LabPro and Barometer in his apartment. He ran a length of rubber tubing from the Barometer through an open window. Even though the power went out sometime during the storm, the LabPro collected data throughout the storm using battery power.

Brian made it through the storm safely and captured some great data.
