Field of Science or Math
The Barometer is designed for weather studies. It can also be used as an altimeter, if you have a portable computer or CBL. This sensor was designed to be an accurate, reliable barometer as part of a weather station. It is temperature compensated, so changes in room temperature will not interfere with the data. It has a voltage regulator, so changes in the computer's power supply voltage are not a problem. It is expecially interesting to watch pressure changes as a storm moves in. If you have an underutilized computer, why not just connect the Barometer to it and graph the barometric pressure for several days? You could connect temperature, relative humidity, or light sensors to the same computer.
