Automação de testes de continuidade em cabos elétricos

Electrical continuity verification is one of the fundamental processes in the quality control of circuits and electronic devices, being essential to ensure system integrity. However, traditional testing methods often rely on manual inspection, making the process prone to human errors, timeconsuming, and inefficient on a large scale. This can result in undetected failures, rework, and financial losses for the company. To address this issue, this study develops an automated device for performing electrical continuity tests onMOBA cables, which are mainly used in heavy machinery such as tractors, excavators, and other vehicles designed for construction and mining. These cables allow the transmission of both data and power, have different wiring patterns, and require precision when verifying their connection paths. The system is based on the ESP32 microcontroller, which manages the tests and transmits the results to a web interface accessible from computers, tablets, and smartphones. The proposed solution reduces test execution time, increases process reliability, and eliminates the need for manual inspection, ensuring greater accuracy in identifying faults such as open circuits, short circuits, and incorrect wiring. Additionally, automation enables standardized testing, making the process faster and more consistent. The developed system presents itself as a viable tool for companies seeking to optimize their quality control processes, offering an efficient and precise method for electrical continuity verification.
