Wind Speed Anemometer Kit with Arduino Uno + Sensor
Build a Wind Speed Anemometer & Gust Logger with Arduino Uno – Complete STEM 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 pile of parts into a fully functional anemometer that measures real-time wind speed in km/h, displays it on an LCD, and logs the highest gust. Perfect for school science fairs, CBSE Class 11-12 physics projects, or curious makers exploring weather instrumentation. The Hall sensor detects each rotation of a spinning cup rotor, while the DS3231 real-time clock timestamps events so you can analyse wind patterns throughout the day.
What You'll Build
You’ll assemble a spinning cup anemometer with a magnet-triggered Hall sensor, wire it to an Arduino Uno, and program it to calculate wind speed from rotation count. The 16x2 LCD shows current speed and peak gust data clearly. By the end of the 3–4 hour build, you’ll have a portable wind meter that can sit by a window or be taken outdoors—exactly the kind of practical project that CBSE evaluators and ATL lab mentors love.
What You'll Learn
- Calculate wind speed from digital pulses using a Hall effect sensor and calibration factor
- Interface a 16x2 LCD with I2C backpack for real-time, easy-to-read output
- Use DS3231 RTC for timestamped gust logging and data retention
- Debug sensor circuits on a breadboard and use pull-up resistors for stable readings

Who This Kit Is For
Designed primarily for school and STEM learners, this kit fits perfectly into CBSE Class 11-12 physics practicals, ATL Tinkering Lab activities, and hobby projects for kids aged 10–15. Parents searching for a hands-on gift that builds real-world engineering skills—without requiring prior soldering or coding experience—will find it hits the mark. Even B.Tech first-year students can use it to quickly prototype an IoT weather station concept.
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 if I get stuck during the build?
Scan the QR code on the box to launch the AI companion trained for this anemometer kit. It walks you through wiring diagrams, code debugging, and calibration. Our team is also available on WhatsApp for real-time support.
Does the kit include the spinning cup rotor?
Yes, the kit contains a lightweight acrylic rotor with three cups and a small embedded magnet. The Hall sensor detects every rotation as the magnet passes by, feeding pulses to the Arduino.
How accurate is the wind speed measurement?
The Arduino counts rotations per second and converts to km/h using a calibration factor. With careful assembly, the reading stays within 5% of a commercial anemometer. Peak gust is stored with an RTC timestamp for science fair documentation.
Can I power this anemometer for long-term outdoor logging?
For extended outdoor use, we recommend swapping the 9V battery for a USB power bank (not included) and protecting the electronics inside a weatherproof enclosure. The DS3231 RTC retains accurate time even during power interruptions.
