I try to find hot wire anemometer circuit board, which can get wind speed without any moving parts.
Few years ago i saw such a circuit board.
Anybody know what companies make sensors like this and where to buy from Europe?
seen this anemometer - Ultrasonic Anemometer - Exhibition / Gallery - Arduino Forum -??
google - hot wire anemometer file:pdf - to get lots of info on hot wire ones
Moderndevice.com sells a couple of "hot wire" wind sensors, but they are extremely difficult to calibrate. Basically, you need a temperature controlled wind tunnel. http://moderndevice.com/product-category/sensors/
