Bluetooth Airspeed sensor

Using a MPXV7002 sensor to measure the pitot/static system.

Estimates on sensitivity

Sensor outputs 1v/kPa

Speed (mph)	Pressure (Pa)
30	110
50	295
80	735

Using this reference to relate speed to dynamic pressure: http://www.engineeringtoolbox.com/pitot-tubes-d_612.html

Based on this it seems our common range of analog swing is 1v out of 5v total, giving us 1024/5 or about 220 counts from a 10 bit ADC. This should be good enough as long as analog noise can be minimized.
