searching for wind speed schematic

[developer]

I need schematic and knowledge on this issue.
the design
the output signal has to feed into serial port o window 98 / 95 based IBM
note book.

any help is appreciated.

That second circuit is very cunning. If you build it, remember that rain
will find its way onto the sensor and affect the calibration.

Hot wire designs are most often used for HVAC and for checking airflow
when designing cooling systems for electronics and machinery.

They are very good with very low flow. Not so good with a stiff breeze.
Outside I think they would be close to useless, but what the heck ...

The boating fraternity here favour a design which uses 3 ultrasonic
transducers arranged in a triangle. Doppler shift due to airflow affects
the transit time of pulses between the sensors. I vaugely recall an
article in Practical Electronics and a google search found this

No moving parts is good when the thing is at the top of a mast in a storm.

Maxim-Dallas offers this article regarding the implementation of a full
weather station using one-wire interface devices. They sell an adapter
that connects a PC's serial port to the one-wire (MicroLAN) network as
well... power-stingy and cheap, too!

Here's a link to the article.
