Design a Simple Prototype Of An IoT-Based Gas Detector System As a Safety Effort On Ships

Abstract

This study examines the design of a prototype IoT-based gas detector system as part of safety procedures on tankers specializing in transporting LNG. Early detection of gas leaks is important in sensitive and high-risk LNG transportation to prevent serious accidents and negative impacts on the marine environment. This study proposes a gas detector system connected to an IoT network, which allows continuous and real-time monitoring of gas conditions on board ships. Placing the prototype device provides important advantages in a scientific context. This study proposes a gas detector system connected to an IoT network, which allows continuous and real-time monitoring of gas conditions on board ships. Placing the prototype device provides important advantages in a scientific context. Three experiments were conducted on the prototype with LED indicators. The experiment results showed that the red LED light was on as an indication of a gas leak, while the green LED light indicated a safe gas condition inside the prototype device. The system design method includes the selection of the right gas sensor, the development of reliable hardware, and the use of IoT technology for the direct transmission of gas detection data to the control center. System implementation involves hardware and software integration, system reliability testing, and performance evaluation in simulations and real-world situations. The prototype test results showed a similar response to the use of portable gas, matches, and gas stoves. When a gas leak occurs, the buzzer is active, and the LED indicator is red. The first sensor sounded at 0.74 seconds in the portable gas test, 0.55 seconds in the match test, and 1.84 seconds in the gas stove test. Thus, the system provides a consistent and reliable response in detecting gas leaks. This research contributes to developing better maritime security technology, protecting the marine environment, and maintaining the safety of LNG transportation operations.
