Wind Speed Alarm for Crop Protection Variant 14 Kit with Arduino Uno + Sensor
Wind Speed Alarm for Crop Protection — Arduino Uno-Based Kit with Hall Sensor
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Protect crops from sudden gusts with a custom wind speed alarm. You'll build a system where a Hall sensor reads anemometer rotation—every pulse representing wind speed—and triggers a relay to lower protective netting automatically when the wind gets too strong. It's agriculture meets electronics, and you can complete it in a single afternoon.
What You'll Build
You'll assemble a working wind monitoring station around an Arduino Uno. The Hall sensor detects the magnet on a spinning anemometer; you'll program the Arduino to count pulses per second, convert to wind speed, and compare against a threshold you set. The moment wind exceeds that limit, the relay activates (imagine it lowering a windbreak net), the buzzer sounds, and the two LEDs flash red—giving you both an automated response and a clear alert.
What You'll Learn
- How to interface a Hall effect sensor with Arduino and calculate RPM from magnetic pulses
- Writing threshold logic to control a relay and buzzer based on real-time sensor data
- Building a circuit on a breadboard that includes flyback diodes to protect the relay
- Applying automation to real-world farming—using sensor inputs to trigger physical crop protection

Who This Kit Is For
Designed for CBSE Class 11-12 students exploring sensor-based automation, ATL Tinkering Lab innovators, and young electronics enthusiasts age 10+. It's also a great starter project for first-year B.Tech ECE/EEE students needing a practical mini-project in agricultural IoT. No prior soldering needed—everything plugs into the breadboard.
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 to open the AI companion—it knows every connection and line of code for this kit. You can also send a WhatsApp message for human support within 2 hours.
Does the kit include the anemometer and windbreak netting?
The kit provides all electronics: Hall sensor, relay, buzzer, and Arduino. You'll need to build or repurpose a simple anemometer (like a rotating cup with a magnet) and a windbreak mechanism; the AI companion suggests simple DIY options using household materials.
Can the relay directly operate a large motor for lowering netting?
The 5V relay can switch low-power DC motors or control signals. For heavy-duty motors, use it to drive an external contactor or motor driver. The included 1N4007 diodes protect your circuit from inductive spikes.
What if the alarm triggers too early or too late due to inaccurate wind readings?
You can fine-tune the threshold in the Arduino sketch. The AI companion guides you through calibrating pulse counts to actual wind speed using a simple test setup.
Hall sensor on anemometer triggers relay to lower windbreak netting when wind speed exceeds threshold.
