Abstract

The development of the Internet of Things (IoT) has enabled wireless battery monitoring through web-based platforms. This study aims to design and develop a wireless battery monitoring system capable of monitoring battery voltage, current, power, battery temperature, ambient temperature, and inverter output voltage while providing remote relay control. The system employs an ESP32 microcontroller integrated with INA219, ZMPT101B, DS18B20, and DHT22 sensors, with ThingSpeak as the monitoring platform. The research method includes system design, implementation, integration, and performance evaluation through sensor accuracy and wireless communication testing. The results show a 100% communication success rate with an average transmission interval of 15 s. The average measurement errors were 0.44% for voltage, 0.46% for current, and 0.26% for battery temperature, while the relay control function operated successfully. These results demonstrate that the proposed system provides reliable wireless battery monitoring and remote relay control based on IoT.
