AI-powered currency detection system running YOLOv8 on Raspberry Pi 5 with Pi Camera Module for real-time Indian banknote recognition. Image preprocessing pipeline—resize, noise removal, brightness enhancement—feeds YOLOv8 for feature extraction, detection, and classification using a trained Indian Currency Dataset model. System outputs recognized currency via text-to-speech engine and speaker, enabling accessible, hands-free currency identification. Fork this diagram to customize preprocessing steps, swap YOLOv8 versions, or adapt for other currency datasets and edge hardware. Demonstrates best practices for deploying production ML inference on resource-constrained IoT platforms with audio feedback.
