Agriculture plays a major role in the Indian economy, but crop damage caused by birds and wild animals is a serious problem for farmers. Traditional methods such as scarecrows, fencing, and manual monitoring are not fully effective and require continuous human effort. This paper presents a Smart Laser Repellent Technology for Sustainable Farming using Artificial Intelligence, IoT, and renewable energy. The proposed system uses a webcam and a YOLOv8/TensorFlow-based object detection model to identify animals entering the farm area in real time. Once an animal is detected, the system activates a laser module and siren to scare away the intruder without causing any physical harm. An ESP32 microcontroller controls the servo motors, laser module, and siren system. The entire setup is powered using a solar panel, making it suitable for remote agricultural fields. The proposed system provides automated monitoring, real-time detection, reduced labor cost, and ecofriendly crop protection for smart farming applications.
