    Abstract
    We are in the 21st century, and nowadays many of us are concerned about our surroundings and environment. Ever since the industrial evolution the greenhouse gases level increased. So does the concentration of carbon monoxide gas in the atmosphere. Carbon Monoxide gases are present in various workplace and its presence is more significant due to burning of hydrocarbons. Day-by-day, the concern regarding the level of Carbon Monoxide is also arising due to such increase in industrial growth. Such problems cannot be overlooked nowadays. There are many sensors developed and used for sensing the level of Carbon Monoxide in various hazardous places like coal mine, sewage, etc. In our thesis we have been working with one such sensor which is the MQ-7. This sensor is easily available and affordable in our country Bangladesh. MQ-7 is a highly sensitive sensor for the determination of the level of carbon monoxide via an optical filter. In our thesis we have completely analyzed the analog and digital output of this sensor with various materials which gives out various levels of Carbon Monoxide when burned. We have discussed the relationship between the concentrations of Carbon Monoxide with the analog voltage reading in order to calibrate the sensor and besides we have carried out some simulation to support our data. Details of our work will be discussed in the following chapters.
