        abstract = {Pests and trespassing animals remain dominant sources of agricultural loss and health hazards in rural and urban areas. Conventional control schemes, such as chemical pesticides and physical barriers are mostly ineffective, environmentally dangerous, and economically ineffectual. This paper shows the design and development of a solar-powered ultrasonic repellent system that can identify and chase away various types of pests and animals with ultrasonic frequencies. The system includes microcontroller (ATmega328P), voltage regulator (LM7805). The system has both manual and remote-controlled modes and has the design that is compact, weather-proof, low-maintenance for agricultural and residential uses. Performance testing revealed stable output with ±5% accuracy and efficient repelling action against mosquitoes, rodents, cockroaches, bats, etc. A comparative life cycle cost study showed that the system to be running at a fraction of the cost of chemical- alternatives, providing a greener and more sustainable solution for long-term pest management. The multi-frequency, green system shows great promise in facilitation of productive agriculture, public health, and environmental sustainability.},
