Smart Warehouse Design With GAS Leak Detector and IoT Based Security System

Abstract

Security is one of the most important aspects of a system or environment, such as homes, offices, campuses, villages, cities, shopping centers, gas warehouses and other locations. LPG gas is a basic need that is distributed to the people of Indonesia through LPG gas bases or warehouses. It is possible for LPG gas cylinders to leak where detecting the occurrence of LPG gas leaks is quite difficult and even more so when the base is in a condition where no one is around, there is a high probability of explosion and fire incidents. The design of Smart Warehouse with a gas leak detector and security system based on the Internet of Things (IoT) aims to improve the security and efficiency of warehouse operations. In this research, the developed system utilizes the MQ-2 sensor for gas leak detection and the RC522 RFID module for access control and security monitoring. The results show that the MQ-2 sensor is able to detect gas leaks and send data to the microcontroller in real-time and provide early warning if a gas leak is detected. Meanwhile, the RC522 RFID is used for warehouse owner identification and authentication, preventing unauthorized access and managing inventory more effectively. The integration of these two technologies in the IoT platform enables remote monitoring and control of the warehouse through the Blynk app, which improves responsiveness to potential hazards and strengthens warehouse security. The system is expected to provide an effective solution to mitigate security risks and improve overall warehouse management.
