Industrial IoT Indicator Light Detection Dataset (IILD)

The Industrial IoT Indicator Light Detection Dataset (IILD) contains 3,853 images and 36,337 annotated instances covering 14 fine-grained categories of indicator lights, encoding physical type (cylindrical, surface-mount device, network port type, housed cylindrical), color (red, green, yellow), and operating state (on, off). Images were collected from real industrial IoT devices under diverse conditions including normal illumination, reflective interference, occlusion, motion blur, long-range multi-device capture, and dense arrangement scenarios. The dataset is annotated in YOLO format and split into training, validation, and test sets in a 7:2:1 ratio.
