Ultrasonic Anemometer

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?

(Bottom of the page)

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

Just follow the first link in the first post, there is a lot of info there..

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.

thanks for your interest but this project done with using ATmega, we need an ultrasonic anemometer doing with pic,

Bit of a nerve haven't you? Asking for pic advice in an Arduino forum!!

? just ask my question sorry if you understan that ? am in nerve situation, my english not very well so ? couldnt tell you ina good way. sorry again

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 smiley-sad could you help us please?

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 Ultrasonic Sensors 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?

I actually got here from info about a PIC controlled one.
You can buy a 1D one here with PIC code.

It is based on this 2003 article:

A group of people have taken that design and tried to configure a 2D version. atmega version
http://hackerfleet.org/dev/wiki/MS0x00/Sensors/Wind

I came running from PIC. Hoping to disassemble a couple of pings and use them.

Hi All,
HAs anyone any specification or even a code + explanation how to run the TR40-16, I just purchased from ALI two and expect for the diameters and picture there is nothing....
Thanks for EVERY piece of information
