The protection of crops from birds and animals is a significant concern for farmers worldwide. Birds and animals such as crows, sparrows, goats, and cows often cause substantial damage to crops, leading to financial losses and reduced yields. Traditional methods of crop protection, such as scarecrows or chemical repellents, have limitations in their effectiveness and sustainability. This research has developed a prototype designed for the detection and repulsion of birds and animals within agricultural environments. The prototype features a motion detection system and an object detection model, which activates a repellent that generates a certain frequency to disturb the birds and animals. This prototype consists of PIR sensors as detectors to detect movement and a camera to capture real-time footage for object detection. If and only if the detected object is a bird or an animal, a signal is sent to the Arduino. The Arduino then determines the respective frequency to be played through a frequency-generating system. The intrusion will be repelled by the emitted ultrasonic waves.
