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 |

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.
