Which model anemometer you are using? Give its full name, link to datasheet and on which PIN of ATmega328 you have connected it. Also attach the picture of sensor.

Thanks for the assistance sir but i aint getting few of the things in your mentioned code like why are we taking the factor of 6000000? and that what is this line doing in the loop?
if(!(US_PIN & (1< i mean what are we checking here?
Secondly,why and how are this 0xffff and 0xfffe used for here?

See this tutorial to understand how we check if a bit in a byte is set or clear
