Liquefied Petroleum Gas (LPG) cylinders are manufactured in accordance with international standards, necessitating rigorous testing prior to market release. This research aims to develop a cost-effective control system to address challenges identified at the hydrostatic pressure testing station of the Tajora LPG Manufacturing Factory. The primary objective is to automate and monitor the hydrostatic pressure testing process, ensuring product safety and compliance with quality standards. This study developed a microcontroller-based control system for automating and monitoring the hydrostatic pressure testing process of LPG cylinders at the Tajora Manufacturing Factory. By replacing expensive PLCs with microcontrollers, the system effectively manages various components, ensuring product safety and quality compliance. Extensive simulations validated the system's performance, and the software was adapted for similar applications, demonstrating its versatility and cost- effectiveness............. Keywords:..........
