This pressure sensor is a very high accuracy (1m) which converting from normal pressure into some digital serial data output. This boardusing a sensor as capable as the BMP180 you can achieve accuracy of 1m, with noise of only 17cm in ultra high resolution noise. The device will operate at only 0.3uA meaning low current draw for battery powered applications.
