Abstract
The reliability of the Signalling and Communication (Sigcom) system in the South Sumatra Light Rail Transit (LRT) is highly dependent on the availability of backup power supplied by an Uninterruptible Power Supply (UPS). This study aimed to design and develop a UPS battery health monitoring prototype based on an ESP32 microcontroller using an INA219 sensor to monitor battery voltage and current in real time. The research employed a Research and Development (R&D) method with a quantitative descriptive approach, consisting of observation, system design, implementation, and performance testing. The test results showed that the sensor achieved measurement deviations of 0.01–0.02 V for voltage and 0.01–0.02 A for current compared with standard reference instruments, indicating satisfactory measurement accuracy. The system successfully displayed battery condition data on an LCD, enabling easier monitoring and supporting preventive maintenance activities. The developed prototype has the potential to improve UPS reliability and can be further enhanced through the integration of Internet of Things (IoT) technology, data logging, and automatic notification features to establish a more effective battery monitoring system.
