I've been looking around at the types of anemometers which I would like to add on to my arduino weather station.

I came across this one (http://arduino.cc/forum/index.php/topic,53569.0.html) which looks very interesting. Has anyone here built it recently? What pitfalls did you run into? I would very much like to build it but would like to know what problems, if any, other people had before I tackle it. It looks tricky :)

Also regarding the transducers - how critical is it that I get the exact model number "T/R40-16B". I'm having problems locating it locally. Would any of these work?

I'd suggest that any 40kHz unit will do since you are only looking at a few cms of range.  However a waterproof version is recommended as it will be exposed to weather and enclosing a non-weatherproof version will seriously affect its performance - see previous thread on waterproofing u/s sensor.  http://arduino.cc/forum/index.php/topic,91647.0.html

Thanks - I think I"ll order the ones of Futurlec then - they are waterproof and 40Khz.

hello guys,
we have trouble with ultrasonic anemometer using pic , we need circuit of this anemometer and which sensor we should use
could you help us immediately :(

thanks for your interest but this project done with using ATmega, we need an ultrasonic anemometer doing with pic, we searched on the internet but we didnt find anything about that :( could you help us please?

I believe that this is the only ultrasonic anemometer on the web which has
enough detail to enable it's actual construction.

I have replied to your email and hope that it will put you on the right track.

Cheers.

There might be no such project on the internet. The hardware is typical the same (PIC and Arduino are not too different) but you have to find out which pic lines to connect to and how to implement the math formulas on the pic.

Which pic processor are you using? there are many IIRC.

i have problem about T/R40-16B, i couldnt find it anywhere to order . We just found this site http://www.futurlec.com/Ultrasonic_Sensors.shtml#TR40-16OA00 can we use this site and which transducer we can use? or any suggestion can you give us?
thank you
best regards

That looks really nice. Given that it's marine equipment though and given that a cursory search couldn't find a price anywhere, I expect it is expensive. Is it?

@VENTS
Is there also English information available on the website?
