A rugged anemometer designed for outdoor wind speed measurement with a simple analog voltage output. Connect it to any microcontroller's analog input for easy wind speed readings — no complex protocols or libraries required.
Wiring is straightforward: connect the black wire to ground, the brown wire to 7–24V DC power, and read the analog voltage on the blue wire. Output ranges from 0.4V (0 m/s) to 2.0V (32.4 m/s). The weatherproof twist-disconnect connector makes installation and maintenance simple.
Key Features
- Analog Voltage Output – 0.4V to 2.0V proportional to wind speed
- Simple 3-Wire Connection – Power, ground, and signal — no complex setup
- Weatherproof Connector – Twist-disconnect for easy installation and removal
- Rugged Outdoor Design – Built for long-term outdoor deployment
- Wide Power Range – 7–24V DC (tested successfully with 9V)
Specifications
- Output – Analog voltage (0.4V to 2.0V)

Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
