Bird Scarer Ultrasonic Emitter Kit with Arduino Uno – Protect Crops Without Harming Birds

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 your farm or garden from bird damage with a motion-activated ultrasonic deterrent you build and program yourself. This kit combines a PIR motion sensor and high-frequency sound bursts to scare birds away before they can feast on your crops, without chemicals or harm. Ideal for paddy fields, fruit orchards, or backyard gardens.

What You'll Build

A fully functional bird scarer that detects avian movement within a 5-7 meter cone and emits a burst of 40kHz ultrasound — inaudible to humans but startling to birds. The system runs on a 9V battery and can be mounted on a pole or tree near your crop zone.

What You'll Learn

• How PIR sensors detect motion and trigger digital outputs
• Programming Arduino to process sensor data and drive ultrasonic transducers
• Using transistors as switches to amplify signals for high-frequency emitters
• Real-world application of electronics in smart farming and crop protection
