3-Cup Aluminum Wind Speed Sensor – Adjustable Wind Anemometer with 0–3.8 V Output for Weather & Environmental Monitoring

Harness accurate, real-time wind data with this 3-Cup Aluminum Wind Speed Sensor. Built for reliability and precision, this wind measuring instrument converts air flow into rotation and outputs an analog signal (0–3.8 V), making it ideal for weather stations, environmental monitoring, farming, sailing, or home-grown DIY weather setups. Its durable construction and omnidirectional cup design ensure consistent wind speed readings regardless of wind direction — perfect for those who need dependable wind data.

Key Features

• Classic three-cup design for 360° wind capture — rotates smoothly in any wind direction. ecosentec.com+1

• Aluminum alloy (or high-strength material) build for durability and stability, suitable for long-term outdoor use.

• Provides analog output (0–3.8 V), compatible with most data loggers, micro-controllers, or weather station units for easy integration.

• Low-friction bearings improve sensitivity and allow detection of low to high wind speeds with good accuracy. walmart.com+1

• Simple mounting — fits standard 4 cm (≈1.6 in) mounting holes or poles for easy installation on rooftops, masts, or towers. walmart.com+1

Why Choose Our 3-Cup Aluminum Wind Speed Sensor
Unlike handheld or prop-based devices, a cup-type anemometer offers robust, continuous measurement and works reliably in changing wind directions without needing re-alignment. codasensor.com+1 The analog voltage output means you can easily connect it to common data-logging or microcontroller systems for automatic wind monitoring. Its durable aluminum build and classic design make it a practical, long-lasting sensor for hobbyist weather stations or more advanced environmental monitoring systems.

Perfect For

• DIY weather stations for home, school, or farming use.

• Environmental monitoring — agriculture, forestry, or air quality studies.

• Marine, sailing, or boat use where accurate wind data is needed.

• Wind-powered projects, small wind turbines, or renewable energy tests.

How to Use
Mount the sensor on a pole or rooftop at sufficient height to avoid obstructions. Connect the analog output to your data logger or microcontroller. As the cups spin from wind, the sensor outputs a voltage between 0 and 3.8 V proportional to wind speed. Use calibration or conversion data to translate voltage readings into wind speed units (e.g., m/s, km/h, mph).
