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.
