From the MPX2010 datasheet:
The MPX2010 series silicon piezoresistive pressure sensors provide a very accurate and linear voltage output directly proportional to the applied pressure. These sensors house a single monolithic silicon die with the strain gauge and thin film resistor network integrated. The sensor is laser trimmed for precise span, offset calibration and temperature compensation.
The MPX2010 can mesaure up to 10 kPa (in water depth equals 10 meters) and there are other MPX20xx sensor like the MPX2050 that can mesaure up to 50 kPa (about 50 meters depth).
