A device used to measure wind speed. It is mostly used by meterologists and weather forecasters.
An anemometer measures wind speed. Whether is it mph, fps, m/s, knots, furlongs per fortnight, etc., all depends on the application.
An instrument that measures the altitude of the sun is called a sun altitude indicator or a sun sensor. These instruments typically use a combination of sensors, such as inclinometers and light sensors, to determine the angle of the sun relative to the horizon. This information is crucial for various applications, including navigation, astronomy, and solar energy systems.
