Please note that the wind vane "points" in the direction from which the wind is blowing. When installing and positioning your weather meters, ensure that any direction markings are pointed in the correct orientation. If you choose different values to indicate directions, be sure to mark then accordingly. There are also very tiny, barely-visible direction indicators on all four sides of the wind vane. It is generally called a meteorological instrument or wind speed meter. The physicists also this device to know the direction of airflow. This instrument is mostly used by the meteorologists, to study whether conditions. However, we recommend having the value at degree 0 represent North for ease of use. An instrument that is used to measure the speed, pressure, velocity, and direction of the wind is known as Anemometer. Since the values outputted by the wind vane are are based on degrees, you can, in theory, have any value represent any direction.
ANEMOMETER WEATHER HOW TO
For an example of how to calculate this, please reference the datasheet linked in the Resources and Going Further for the meters. Measuring the voltage output with an analog-to-digital converter on your microcontroller allows you to determine the direction the wind vane is pointing.Īs the voltage output will depend on the value of the external resistor used, there is not one common conversion function. With the use of an external resistor, a voltage divider can be created. An anemometer is an instrument that also measures wind pressure. It also describes any wind speed instrument useful in meteorology. This term is derived from the word anemos, which is of Greek origin. It is also the common weather station instrument. Anemometer Wind Speed and Wind Direction Sensor. Anemometer is a device useful in measuring wind speed and direction. Featured Handheld Anemometers See all Handheld Anemometers » Kestrel 1000 Pocket Wind Meter Current Wind Speed Average Wind Speed Maximum Wind Gust Waterproof Our Price: 87. This power-efficient anemometer accurately measures wind direction and speed. Measures temperature, wind speed/direction, rainfall, humidity, barometric pressure, and more. The AN100 Anemometer has a big illuminated display and can show both temperature and air flow or speed at the same time.
The eight switches and their respective resistors internally on the wind vane.Īs the wind vane rotates, a magnet closes the reed switches, and may close two at a time due to their proximity to each other.
