Implementation Internet of Things (IoT) in Fire and LPG Leakage Detection System Based on Esp32 with Multiuser Notification

Abstract

The community's late realization of the fire is often a cause of the delayed handling of fires. Therefore, a fire detection system that can be monitored remotely is needed to overcome the delay in handling fires. This study aims to create a fire and LPG leak detection system based on ESP32 with multiuser notification through IoT implementation in a Prototype. The system is installed in a miniature room measuring 30cm x 30cm x 30cm. The fire detection system uses KY-026 sensors, the LPG leak detection system uses MQ-6 sensors, and multiuser notification uses Telegram. The study’s result showed that the fire detection system can detect fire up to a distance of 820cm, has 100% detection accuracy, and uses two sensors can reduce blind spots. The LPG leak detection system can detect small gas leaks up to a distance of 18cm in a miniature room, has 100% detection accuracy, and uses two MQ-6 sensors can speed up the detection. For sending multiuser notifications via Telegram, it has 100% accuracy and a throughput of 22,785 notifications per minute but has a high jitter of 1,238 seconds and a notification delay of between 1,842 and 1,905 seconds.
