Abstract
CO2 gas is a poisonous gas that is invisible and odorless. Now days, the CO2 gas detection system uses the direct contact (in situ) method with the gas to identify its existance and quanities. The further determination is being carried out in the laboratories. This method is ineffective and inefficient because of some unpractical procedures as in the real situation collecting the gas could be dangerous. Therefore the development of a non-contact detection system will be important and challenging wor. One method of developing a non-contact gas detection system is using the Optical Gas Imaging (OGI) method. In this paper, a non-contact CO2 gas measurement system has been designed based on infrared absorption using an infrared thermal camera. The experiment is carried out on a laboratory scale with three main components of an infrared light source, a gas source and a detector. From the results, unique pattern of gas of CO2 coudl be distinguised from the open air and also mixed gas through the equalized histogram.
