Wind Vane
Available with a lead time
Expect dispatch between Jun 26 and Jun 30
The wind vane indicates the direction of the wind. Internally, on the vane are eight switches, each with a unique resistor. As the wind vane rotates, a magnet closes the reed switches, and may close two at a time due to their proximity to each other. With the use of an external resistor, a voltage divider can be created. Measuring the voltage output with an analog-to-digital converter on your microcontroller allows you to determine the direction the wind vane is pointing.
There is not one common conversion function, as the voltage output will depend on the value of the external resistor used.
Since the values outputted by the wind vane are based on degrees, you can theoretically have any value represent any direction. However, Sparkfun recommend having the value at degree 0 represent North for ease of use. There are also very tiny, barely visible direction indicators on all four sides of the wind vane. If you choose different values to indicate directions, mark them accordingly. When installing and positioning your weather meters, ensure that any direction markings are pointed correctly.
Please note that the wind vane "points" in the direction from which the wind blows.
This is the same wind vane used with the Weather Meter Kit.
