Depends upon how accurate you wish to be...
If you just want to sense wind, you could use your hand
(dampen it and it will be more sensitive). You could use
a sheet of cardboard or thin aluminum hanging from two
strings outside. If it moved, there was some amount of wind.
Or, if you wanted an accurate measurement, you could use
an anemometer pointed at the source of the wind. An anemometer is a electronic device with a propeller or other sensing device attached to an electronic circuit board and a
meter. When the propeller spins (or the sensor makes a detection of wind) the circuit board reads that information and
deleivers an output to the meter which shows you how much
wind there was.
Wind speed is measured in miles per hour, or knots. So meters
either have MPH or KT scales on them. Some fancy units may have both scales.

A gandget called an anemometer. You've probably seen one if you've been around airports -- it looks like three wires radiating from a central axis, and with a hemispherical cup at the end of each. By spinning this thing around the wind measures its speed just as the speedometer measures the speed of a car by counting the revolutions of the wheels.

The main instrument used to measure the speed of the wind is an anemometer. You can read more about it on the link below.

wet your forefinger, raise it high up in the air and place a flag between your last two fingers. it will reveal the wind direction and gust amount.
