Abstract
Abstract: This study aims to develop and evaluate a microcontroller-based hydrogen gas monitoring system using the MQ-8 sensor. The research includes sensor calibration, sensor performance testing, and protection system testing. Results show that the MQ-8 sensor can detect hydrogen concentration changes in real time, while the protection system effectively provides warnings and activates safety controls when dangerous gas levels are detected. The system can therefore be used as an effective monitoring and protection tool for hydrogen generator safety.
