Nevertheless, the modern handheld anemometer measures the various aspects of wind. It includes temperature, pressure and humidity. Weather stations usually use anemometers for carrying out metrological functions. There are five types of anemometers. They are windmill anemometer, sonic anemometer, cup anemometer, hot wire anemometer, and laser Doppler anemometer.
A handheld anemometer is famous as personal anemometer. It is only few inches in length and width. It measures the wind perfectly within percentage5. Most of the instrument calculates wind speed in km/h, m/s, and mph. Even the sudden variation of direction and strong wind cannot affect it.
