Anemometer Kit with Arduino Nano + Hall Effect
Measure Wind Speed with Arduino Uno: DIY Anemometer Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform a handful of electronics into a real-time wind speed instrument. Whether you are tracking breeze patterns for a school weather station or prototyping a smart agriculture sensor node, this anemometer translates spinning cups into precise km/h readings on a crisp LCD display. No guesswork—just data you can log, graph, and act on.
What You'll Build
A working cup anemometer that counts rotations with a Hall effect sensor, processes the signals with an Arduino Uno, and displays instantaneous wind speed in kilometers per hour. It is a complete, portable weather tool you can mount outdoors or integrate into larger data-logging projects. The I2C LCD keeps wiring simple, and the breadboard layout gives you full insight into every connection.
What You'll Learn
- Interface a Hall effect sensor to detect magnetic field changes without physical contact.
- Write Arduino code to convert sensor pulses into wind speed using rotational physics.
- Display real-time data on a 16x2 LCD via I2C, simplifying wiring and code.
- Troubleshoot sensor noise with pull-up resistors and bypass capacitors for stable readings.

Who This Kit Is For
Ideal for CBSE Class 11–12 students working on physics investigatory projects, B.Tech ECE and EEE undergraduates experimenting with sensor-based systems, and ATL Tinkering Lab mentors guiding Smart India Hackathon prototypes. If you need a reliable wind speed measurement module for an IoT weather station, this kit gives you a solid foundation without the frustration of parts sourcing.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What is the minimum wind speed this anemometer can detect?
The Hall effect sensor with a small magnet on the cup axle can detect rotations from very light breezes (around 0.5 m/s). Calibration depends on cup size and arm length; the sample code includes tunable factors.
Can I power it outdoors for long-term monitoring?
Yes, you can replace the 9V battery with a 5V solar-charged power bank connected to the Arduino’s USB port. Mount the electronics in a rainproof enclosure for permanent outdoor use.
Is soldering required?
No soldering. The kit uses a breadboard and jumper wires, so you can prototype and modify connections quickly. The I2C backpack simplifies LCD wiring to just four pins.
How do I get help if my LCD shows garbled text?
Scan the QR code on the box to chat with our AI companion; it is trained on this exact build. You can also reach us on WhatsApp for personalized guidance within 24 hours.
