A three-cup anemometer kit with 0–5V analog voltage output for building custom weather stations and wind monitoring systems. The aluminium alloy construction provides high strength, weather resistance, and corrosion resistance for long-term outdoor deployment.
The anemometer features a built-in photovoltaic module and industrial microcomputer processor for reliable wind speed measurement. With a 0–30 m/s effective range and 0.1 m/s resolution, it delivers accurate readings across a wide range of conditions. The 0–5V voltage output connects easily to any microcontroller's analog input.

Jargon buster
Plain-language definitions for the technical terms used above.
- ADC
- An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- VCC
- VCC is the positive power-supply connection on a chip or module. Connecting it to the correct supply voltage is needed for the part to power on and helps avoid damaging the electronics.
