### Miniature airspeed sensor

#### for RC plane & UAV

full description

## Brass tube

## mp3v5004dp & mcp3428

- Resolution: 0.2041 Pa/LSB
- Range: [0 836] Pa ($\approx 100km/h $)

## Static sensor noise

- 90 min log @ 100Hz, indoor, still
- Standard Dev : 0.5 Pa

## Flight tests

## Pressure - Speed

$P_{diff} = \frac{1}{2}\rho v^2$

$v = \sqrt{\frac{2}{\rho} * P_{diff}}$

with $\rho = 1.16 $

## results
