<![CDATA[High noise levels in industrial environments can lead to hearing loss, necessitating the use of personal protective equipment (PPE) such as earplugs. However, excessive earplug usage beyond the daily quota often occurs, resulting in waste. To address this issue, an automatic earplug dispenser system was designed and built using RFID RC522 and ESP32, equipped with monitoring via a website and mobile application. This system aims to limit earplug dispensing per user according to the daily limit, automatically record usage data, and simplify distribution monitoring. Based on testing with four RFID cards, two registered (A and B) and two unregistered—the system successfully enforced the daily limit with a 100% success rate. Additionally, both the website and mobile application were proven to connect to the same database and display synchronized data in real time. Overall, the system effectively improves PPE management efficiency, reduces waste, and supports a more effective and well-monitored implementation of occupational health and safety (OHS) programs.]]>
