Anemometer to PWM

Archiver

Stampers,

With a few of you having built weather stations previously, I though I might
ask if anyone has code (or circuit ideas!) for the following application.

I need to take a reed switch closure from an anemometer(DAVIS brand) and
convert it's output to a 0-5 volt signal for an industrial application.

We only need to read "normal" wind speeds, eg nothing gale force!

I'm only asking as I don't want to reinvent the wheel!

Regards

Tim Stockman

Stocky-

My first try would be to feed the anemometer's output to COUNT, then
scale that result to serve as the argument for PWM to generate your
0-5 volts ouput. At first blush, seems it ought to work.


Regards,

Steve

Hi Tim, I have such a circuit and code posted at
