[Paparazzi-devel] Airspeed sensor

[Famille Chateauvieux-Hellwig]

Hi all,

I've seen recently a number of thread on the list questioning for an airspeed 
sensor.
I built such a sensor recently. It didn't fly yet but I believe it works fine 
as 
I get quite stable measurement of my hair dryer !
I could publish this if any body is interested. The construction is basically 
a Pitot tube from sm modellbau in germany (http://www.sm-
modellbau.de/shop/product_info.php?products_id=80&cPath=11) which is connected 
to an freescale differential pressure sensor. The pressure sensor signal is 
adjusted for the required speed range with a operational amplifier of which the 
output is fed into an AVRmega 10 bit ADC.
I can publish an eagle schematic, and a piece of AVR GCC C code. Probably I 
can find again the OpAmp calculation.
Anybody interested?
