RM Young Anemometer to PC

[Stuart Robinson]

I own a (rather expensive) RM young Anemometer along with the Wind Tracker display unit which I make great us off during my hurricane intercepts. For the rest of the year it sits idle in my office.

During the “off seasonâ€￾ I would like to attach it to my house and record wind speeds etc – hopefully being able to log them to my Weather Server. I see that the RM Young Wind Tracker has a 0-5volt output that I could use?

Can anyone suggest a way that I can connect my RM Young to a PC so that I can log the out put – I really want to do this in real time if possible.

In the end I went with a very cheap £30 USB Analogue to Digital interface http://www.pc-control.co.uk/wasp_info.htm

Very interesting, Stuart. Let us know how it works out. I'm particularly interested because I'm using a similar USB device for a servo motor project I'm working on.

Cool. Those USB acquisition units are fun.

I have a full instrument set, less a computer / display for them. They have outputs in varying voltage outputs as such

temp -50 to 150 f = 1-1.00v
humidity 0-100 % = 0-1.00v
windspeed 0-100mph = 0-5.00 v
direction 0-360 deg = 0-5.00 v

Is there any preprogrammed hardware / software+display solution around? I'm not too great of a programmer, and right now dont have the time to learn. I'd like something that uses a GPS to compensate for vehicle heading when giving me direction, and also logs time/location with the data .... as well as embedding the data into my web tracker packet.

I know that is asking alot, but is there anything around that might be of interest?

Just to round off this thread,

I was able to make great use of the W.A.S.P. board to convert the output from my RM Young anemometer (Wind Tracker Display) to be read via an App that I wrote.

I *did* discover a couple of things… I have a strange model of Wind Tracker = the out put voltages is actually 0-2.5V for 540 degrees (I know I was expecting 360) also at 100 mph the output is 2.5V BUT at 200 mph I get 5 Volt – Most Wind trackers give 5 V @ 100 mph and wont give any higher voltage out put from there.

Here is a screen shot of my app.
