This work presents a deployable deterrent system tailored for agricultural environments, integrating embedded intelligence and wireless control. By combining ESP32-based hardware with a YOLOv5 detection pipeline and ultrasonic actuation,thesystemidentifiesandrespondstoanimalintrusions in real time. A lightweight server architecture bridges the microcontroller and mobile interface, enabling remote monitoring and adaptive feedback. Experimental results demonstrate high detection accuracy and low latency, validating the system's potential for scalable field deployment.
