| TITLE | PCB Error Detection using IoT on a Conveyor Belt |
|---|---|
| ABSTRACT | This paper presents a low-cost, IoT-enabled Automated Optical Inspection (AOI) system for detecting printed circuit board (PCB) manufacturing defects. To maximize system stability, the architecture divides the workload: an ESP32-S3 edge device handles real-time hardware actuation (ultrasonic proximity detection and conveyor motor control), while a local server handles intensive image processing. Overcoming the resolution limits and routing complexities of standard microcontroller cameras, the vision subsystem utilizes a commercial smartphone's high-resolution IP video stream. Upon detecting a PCB, the ESP32-S3 halts the conveyor and wirelessly triggers the server to capture an image and execute OpenCV-based image subtraction. This identifies defects like missing or misaligned components, demonstrating a highly scalable and budget-friendly machine vision solution for small enterprises. |
