GAS LEAKAGE DETECTION SYSTEM USING INFRARED RADIATION

The main objective of this project is to build a model for detecting gas using Infrared
radiation (IR), applicable for detecting gas leakage for home and industry usage. It is
always essential to have a reliable and practical gas leakage detection system for
safety purpose especially at home and industry. This project will focus on Liquefied
Petroleum Gas (LPG) detection. The method used to detect gas is by measuring IR
intensity at the source as well as the detector. The IR intensity at detector is less than
at the source since the gas absorbs IR radiation. Student tries to use two IR radiation
sources for this project, which are the transmitter circuit and incandescent lamp.
However, transmitter circuit is not functioned as expected and incandescent lamp is
used to transmit IR radiation. Researches done for this project are understand about
IR and LPG characteristics, search, construct and test the circuits used and understand
how it works, construct a chamber for project model as well as doing experiment for
proving the theory. As a conclusion, this project has exposed to new knowledge of
LPG and IR applications besides introducing a cheap and simple concept of gas
leakage detection, making it a reliable and practical system to be implemented.
