Wind Speed Alarm for Crop Protection Kit with Arduino Uno + Sensor
Arduino Uno Wind Speed Alarm Kit: Protect Crops from Strong Winds Automatically
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a sudden gust of wind automatically triggers a protective net to descend over your vegetable patch. This kit lets you build that exact system—a wind speed monitor that reads pulses from a Hall-effect sensor mounted on a simple anemometer, and when a threshold is exceeded, activates a relay to lower windbreak netting while sounding a buzzer alarm and flashing warning LEDs. It’s a hands-on introduction to smart farming electronics that directly tackles a real agricultural problem.
What You'll Build
You’ll assemble a complete wind-responsive crop protection device. The Hall sensor detects rotation from a makeshift anemometer (magnet on a spinning cup), Arduino converts pulse frequency into wind speed, and when the speed crosses a safe limit, the relay module engages a motor or actuator to pull down a windbreak barrier. The active buzzer and dual red LEDs create an audible and visual alert, ensuring the farmer knows the protection has deployed.
What You'll Learn
- Interfacing a Hall-effect sensor with Arduino Uno to count pulses and calculate RPM/wind speed
- Programming threshold-based logic to trigger a relay, buzzer, and LED indicators
- Using a relay module to control a separate high-power circuit for actuating a motor or solenoid
- Building circuits on a breadboard with diodes, resistors, and power management

How does the Hall sensor measure wind speed?
A magnet attached to a rotating anemometer cup passes the A3144 sensor, generating pulses. Arduino counts these pulses per second and converts the frequency to an approximate wind speed using a simple formula.
What mechanism can I connect to the relay for lowering netting?
You can wire a DC motor, servo, or solenoid to the relay’s output terminals. When the wind threshold is crossed, the relay closes the circuit, driving the motor to pull down a windbreak net or curtain.
Can this kit be used for a school science exhibition?
Absolutely. The automatic crop protection demo clearly shows sensor-to-action logic and has strong real-world agri-tech relevance, making it a standout exhibit.
Hall sensor on anemometer triggers relay to lower windbreak netting when wind speed exceeds threshold.
