Wind Speed Measurement Circut

Hello,
I want to convert the pulses from a Wind Speed Sensor to DC voltage... Say, 0 - 1VDC... How can I do it...

When the wind speed will be low, the pulse duration will be long..... when the wind speed will be high, the pulse duration will be small.... can anyone please help or post a link for making this circuit or suggest an IC which will convert this pulse input to DC of any level, directly..

Thanks...

 

use a rev counter circuit, I.E. number of pulses = volts out

Thanks, it was helpful... Will 'copy' some of these and try to make my circuit...!!

Regards

 

Which is always better than an anel thermamometer;
