Sensing wind speed   Message List  
Reply | Forward Message #721 of 891 |
Hello Guys
I've been looking around and trying to learn something about sensing
wind speed. Apart from anemometers with three cups it appears that my
options are ultrasonic transducers or using a pair of LM335's, one of
which is self heated.
Does anyone have any practical experience with wind speed? Or, has
anyone heard of another way to measure wind speed?

Regards
Chris Holme

Another way which I don't think anyones mentioned, is using differential pressure sensors and a venturie . 2 or 3 sensors could be used to extend the range. ...

... DIY's are also possible for (static) pressure, but I think they can be a bit trickier, for two reasons... Linearity and, if you're doing barometric...
