An anemometer is a device that is used to measure the speed of wind. They are crucial instruments in meteorology, aviation, environmental monitoring, and various industrial settings.
Anemometers come in several types, each employing a unique mechanism to capture and quantify the force of moving air. Most handheld wind speed monitors are designed to be rugged, durable and waterproof in order to withstand the elements and provide reliable measurements in various outdoor conditions.

The choice of anemometer depends on the specific application and the level of accuracy required. Below are some common types:
These are the most common type, featuring rotating cups that capture the wind's force and translate it into rotational speed, which is then converted into wind speed readings.
Also known as propeller or windmill anemometers, vane anemometers use a propeller to measure wind speed. The propeller's rotation speed is proportional to the wind speed. They’re also sometimes referred to as impeller wind monitors, as their propeller blades are protected by a caging unit to protect your hand.
This anemometer uses the pressure generated by the wind to measure its speed.
Also known as constant current anemometers, a hot-wire anemometer is commonly made for hand-held usage and works by utilising a heated wire whose resistance changes with wind speed. By measuring the change in resistance, the wind speed can be determined.
These wind speed test meters have the smallest sensor, which measures both air velocity and temperature. They are commonly used in wind tunnels for circuit board and heat sink analysis.
These advanced wind speed detectors use ultrasonic sound waves to measure wind speed and direction. It has two of three pairs of sound transmitters and receivers mounted at right angles to one another. Built-in electronic circuits measure the time it takes for the sound to make its way from each transmitter to the corresponding receiver. The circuits gauge the difference in speeds of the beams and use that to calculate how fast the wind is blowing.
These devices are used in applications like:
Selecting the appropriate anemometer depends on several factors, including the desired accuracy, measurement range, environmental conditions, and intended application. Consider the specific needs of your project and choose an anemometer that meets those requirements.
