Smart Laser Repellent Technology for Sustainable Farming

Abstract: Agriculture is one of the most important sectors supporting the economy and food production worldwide. However, crop damage caused by birds, wild animals, and intruders significantly reduces agricultural productivity and farmer income. Traditional crop protection methods such as fencing, scarecrows, and manual monitoring are inefficient, labor-intensive, and environmentally harmful. This paper proposes an IoT-based Smart Laser Repellent System for Sustainable Farming that automatically detects and repels birds and animals using laser technology and intelligent monitoring systems. The proposed system uses PIR sensors, ESP32 microcontroller, laser modules, and servo motors to detect movement and activate a rotating laser beam for repelling intrusions without causing physical harm. IoT connectivity enables real-time monitoring and mobile notifications to farmers. The system provides an eco- friendly, cost-effective, energy-efficient, and sustainable solution for modern smart agriculture applications. Experimental analysis demonstrates improved crop protection efficiency, reduced labor dependency, and minimized environmental impact compared to traditional farming protection methods.
