RE: [Paparazzi-devel] Airspeed sensor

[Electro-Technik]

Hi,

There is an airspeed sensor kit available for the Ardu-Pilot, see

http://store.diydrones.com/ProductDetails.asp?ProductCode=KT-0001-01

which could possibly serve as a prototype or test bed.

I hope this is of some help.

Regards

Alan K.

Subject: [Paparazzi-devel] Airspeed sensor

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?

Martial
