## Description

This three-cup anemometer measures wind speed by generating a DC voltage proportional to the rotation speed of its aluminium cups. The faster the wind blows, the higher the voltage output — up to 1.2V at maximum speed. Simply read the analogue output with a microcontroller to calculate wind speed. Designed with a rain-proof housing and a standard Octopus brick connector, it integrates easily with ElecFreaks Octopus series boards and other microcontroller platforms. The three 6 cm half-sphere cups are mounted at 120° intervals on a ~20 cm diameter rotor. Key Features Analogue Voltage Output – DC voltage proportional to wind speed (up to 1.2V) Three Aluminium Cups – 6 cm diameter, mounted at 120° intervals Rain-Proof Design – Suitable for outdoor weather station use Octopus Brick Connector – Plug-and-play with Octopus series boards ±10% Tolerance – Suitable for educational and hobbyist weather monitoring Specifications Cup Diameter: 6 cm Rotor Diameter: ~20 cm Output: DC voltage (0–1.2V analogue) Tolerance: ±10% Ideal For DIY weather stations STEM education and science projects Environmental monitoring with micro:bit or Arduino Outdoor sensor networks
