Anemometer Wind Speed Sensor

The Anemometer Wind Speed Sensor is a common weather station instrument used for measuring wind speed. This anemometer features a weatherproof built and 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 using an Micro-controller such as an Arduino. The voltage will range from 0.4V (0 m/s wind) up to 2.0V (for 32.4m/s wind speed).

The Anemometer is rugged, and easy to mount. The cable can easily disconnect with a few twists and has a weatherproof connector.
