Enhancing Asset Accountability in Vocational Workshops via an Automated Solenoid-Locked Smart Rack System
Keywords:
smart rack, tools management, technical workshopsAbstract
Manual tool management in technical workshops often causes operational inefficiencies and equipment loss. This paper presents "Smart Rack," an automated solution driven by an ESP32 microcontroller. The architecture integrates barcode scanning for user authentication, infrared sensors for real-time tool detection, and a solenoid locking mechanism for controlled physical access. This system incorporates a structured data-logging mechanism to record transactions simultaneously. Empirical results indicate the system achieves a 70% success rate, with response latencies ranging from 0.86 s to 3.86 s and a mean response time of 1.72 s, offering a cost-effective, scalable asset tracking solution for vocational and industrial environments.
