Some time ago I received one of HiTechnic's Barometric sensors that
I experimented with it and wrote a driver class for leJOS NXJ, the Java platform for the NXT, which I used to program my little machine that integrates the sensor: the NXT Barometer.
"can be used as part of a weather station or to monitor altitude. The sensor can be used to read both atmospheric pressure and temperature"as HiTechnic states.
