Animal intrusion in domestic areas is an increasing concern due to urbanization and reduced natural habitats. This project presents an Animal Deterrent System for Domestic Areas employing dual frequency ultrasonic sound to enhance repellent effectiveness. The system generates ultrasonic waves that alternate between two frequency ranges to prevent animal adaptation. In addition to ultrasonic deterrence a high intensity LED flashing module is incorporated to provide a visual stimulus that further discourages animal entry, particularly during low light and night time conditions. The system controls frequency switching and LED flashing operations to ensure reliable performance with low power consumption. The proposed system is non-lethal, eco-friendly and suitable for residential environments. Experimental observations demonstrate improved deterrence compared to single frequency systems, making the proposed approach a practical solution for domestic animal intrusion control.
