This is a stand-alone airspeed sensor. Includes Pitot Tube and 12cm Female to Female Servo Cable.The MPXV7002 series piezoresistive transducer in the small outline package (SOP) is a state-of-the-art monolithic silicon pressure sensor designed for a wide range of applications, but particularly those employing a microcontroller or microprocessor with A/D inputs. This patented, single element transducer combines advanced micromachining techniques, thin-film metallization, and bipolar processing to provide an accurate, high level analog output signal that is proportional to the applied pressure. The MPXV7002 is designed to measure positive and negative pressure. In addition, with an offset specifically at 2.5V instead of the conventional 0V, this new series allows to measure pressure up to 7kPa through each port for pressure sensing but also for vacuum sensing (refer to the transfer function in the data sheet for more detailed information). Features: -2 to 2 kPa (-0.3 to 0.3 psi). 0.5 to 4.5 V Output Weight: 0.1 oz; 4 g (Just the sensor)Data Sheet：http://www.freescale.com/files/sensors/doc/data_sheet/MPXV7002.pdfSet up instructions：http://code.google.com/p/ardupilot-mega/wiki/Airspeed
