Adafruit Anemometer Wind Speed Sensor w/Analog Voltage Output

An anemometer is a device used for measuring wind speed, and is a common weather station instrument. This well-made anemometer is designed to sit outside and measure wind speed with ease.To use, connect the black wire to power and signal ground, the brown wire to 7-24VDC (we used 9V with success) and measure the analog voltage on the blue wire. The voltage will range from 0.4V (0 m/s wind) up to 2.0V (for 32.4m/s wind speed). That's it!The sensor is rugged and easy to mount. The cable can easily disconnect with a few twists and has a weatherproof connector. This anemometer is not IP rated, so it is not designed to withstand water ingress without additional gaskets or protection.
