14-year-old blogger and LEGO fan Joey Kelly of Stayton, OR lucked into a pressure sensor from Dexter Industries, and wrote up a detailed report.

The dPressure is a very interesting sensor. It has two nozzles: the first on can sense pressure in both PSI (Pounds per Square Inch), and kPa (Kilopascals). The second nozzle can be used as a vacuum sensor (sense negative gauge PSI or kPa). It’s also very easy to use too! All you have to do is connect an NXT wire to the sensor and to the NXT and there you go! It, so far, can only be programed in NXT-G 1.X, and NXT-G 2.0.

The new sensor is due out by the end of the month. Readers: what would you do with a Lego pressure sensor? [via The NXT Step]
