Gas Leak Detector Using PIC16F877A Microcontroller on Board Ship

Abstract

 The liquified petroleum gas or LPG vessel and Liquified natural gas or LNG vessel mostly has a separate cargo pump room for operation of loading and discharging cargo. This place mostly has a tendency leakage of cargo that may endanger to person on board ship and environmental pollution. Some gas cargo there are more danger that other cargo if there have leaks because most of the gas are seamless and odorless and hard to identify if have a leakage in that place. The objective of these design project is to detect the presence of gas in surroundings if there have leakage on the system and will alert the operator or other crew by sound the alarm, blink the LED, and the description also will appear on LCD, so that the crew member will know the current situation and ready take for another action. This system is robust and cheap system because use of the microcontroller unit (MCU) system. The system is created using the Proteus 7.6 software and PIC C Compilers for simulate the design before it is be test on hardware model. The 10-bit microcontroller used for these systems. The sensor MQ-2 use for detecting gas leak like LPG, butane, methane, alcohol, propane, Hydrogen, and smoke.
