Wind Speed Sensor Anemometer with 0-5V Analog Output

The ShillehTek Wind Speed Sensor is a three-cup anemometer with a clean 0-5V analog output that rises linearly with wind speed, making it one of the simplest ways to add real wind measurement to Arduino, ESP32, and Raspberry Pi projects. Read it directly with an Arduino analog pin, or pair it with an external ADC such as the ADS1115 for Raspberry Pi and other boards without analog inputs. The rugged cup-and-shaft design is built for continuous outdoor mounting on a mast or pole, and the analog interface means no libraries or protocols are required - just scale the voltage to wind speed in your code. Use it for DIY weather stations, rooftop and garden monitoring, solar and agriculture projects, drone ground stations, and long-running IoT wind loggers.
