Arduino Bird Deterrent Kit - Ultrasonic Crop Scare System

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Birds can destroy a harvest in hours. This kit enables you to build a sensor system that detects their movement using a PIR module and emits 40kHz ultrasonic pulses to drive them away - hands-free, 24/7, and powered by a simple Arduino Uno. Whether you're protecting a paddy field or a small kitchen garden, you'll deploy an effective, non-lethal deterrent.

What You'll Build

A motion-activated ultrasonic bird repellent you can place in any crop zone. When the HC-SR501 PIR sensor senses movement, it triggers two 40kHz ultrasonic transducers through a transistor driver circuit, producing high-frequency sound disturbing to birds but inaudible to humans. The unit runs on a 9V battery, making it portable and easy to deploy across multiple sites.

What You'll Learn

• Interfacing PIR motion sensors with Arduino Uno to detect warm bodies reliably.
• Driving ultrasonic transducers using BC547 transistors and 1N4007 diodes for safe switching.
• Programming delay and burst logic to pulse ultrasonic sound effectively.
• Designing low-power, battery-operated field electronics for agriculture.
