Looking for a air speed sensor and scaling circuit

[luckyflyer]

Has anyone experimented with air pressure sensors? I would like to build a small air speed circuit with a scaled linear output. I have googled airspeed sensor but didn't come up with much.

Look at Freescale MPXV5010DP and this article.

For very low airspeeds you might also look at the "Micro Gust Thermal Anemometer" project article featured in the February 2006 issue of Nuts and Volts magazine.

Unfortunately the complete article is NOT online but it is briefly described at the following URL. They also sell a fully assembled board for $30.

The anemometer project uses an LM399 Zener diode as a sensor to measure tiny air currents. Although the article does not provide any exact numeric specification for how sensitive it is, the author mentions that he can puff several feet away from the sensor and see the output respond. The board requires 15 Vdc and draws 20 ma at no wind.
