Three-Cup Aluminium Wind Speed Anemometer Sensor, 12-24V, 4-20mA

This robust three-cup anemometer measures wind speeds up to 30 m/s and outputs an industrial-standard 4 to 20 mA signal. Built from durable aluminium alloy, it provides high strength, weather resistance, and water resistance for outdoor monitoring. It is ideal for makers, students, and hobbyists building custom weather stations and automated environmental systems.

Durable weatherproof construction

Constructed from aluminium alloy, this sensor provides high mechanical strength along with water and corrosion resistance. Its rugged shell and three-cup assembly ensure reliable, long-term operation in demanding outdoor environments.

Measurement range and output

The anemometer accurately records wind speeds from 0 to 30 m/s with an accuracy of plus 1 m/s. It operates on a 12 to 24 V DC power supply, offering low power consumption, strong anti-interference performance, and long signal transmission distances.

Microcontroller wiring and integration

Wiring consists of red for power supply positive (12-24 V), black for power negative, and yellow for the 4 to 20 mA signal output. Adding a 250 ohm resistor between the signal line and ground converts the output to a 1 to 5 V range for easy reading on standard microcontroller analogue inputs.
