Wind Speed

Stampers,
Not wanting to reinvent the wheel, has anyone have a source/ideas for the
mechanical part of wind speed sensors (anemometer...i think???). The three cup
type would be preferable.
I want to use a BS1 (or pic with stamp code) to convert pulses from the
sensor into a 0-5v voltage to be read by another device. It should be able to
handle that with ease I would think?
We do not need massive accuracy, just a rough idea of wind speed.
There also has been mention of a simple (dallas?) device for temp readings.
Can anyone tell me what they are (part no.) and how hard are they to interface
(again wanting to use BS1 or pic with BS1 code).
Regards
Tim Stockman

The three cup type is designed with the radius of each cup
approximately 1/3 to 1/2 of the diameter of the wheel out to the
center of the cup. Then the relationship between wind speed and the
rotation speed of the wheel is near linear. Most wind vendors sell
replacement cups, e.g. Davis Instruments replacement cups cost about
US$15. (I am an authorized Davis dealer, but you can probably find
one down under.)

There are soooo many different economical temperature sensors, having
a variety of interfaces and capabilities. Give us a better idea of
where it will be located.

out of a fan. I know an Anemometer can be used, but for the most part these
are pretty expensive and bulky. I have heard of using a "hot wire" system
but have not found any detailed plans on making one. Has anyone made or used
a fairly inexpensive, fairly accurate and compact device to measure wind
speed? Thanks!

Seems like it was around $20-$40. Not sure what the accuracy would be.

at, logging windpeed. I used an old fan, and calibrated it by measuring the
output voltage while driving with it on top of my truck.
Hey, it's cheap!

i.e., fuel-injection systems. Using a automotive hot-wire "mass-air
sensor" might be a way to quick-start the development. Just put a
constant voltage across the sensor and measure the current (or vice
versa, I'd have to think that) might be a quick start to what you are
looking for. They are fairly expensive (in the tens of $$), so best bet
might be to get one from a junkyard. They are located in the air intake
piping, and they have wires going to them.) There are other kinds of
air sensors, e.g., vane-actuated potentiometers, so make sure the thing
you're looking at has a wire across it. Many, if not all late mustangs
use mass air sensors.

Excellent idea........That will work well!!
