ELECTRONIC NOSE: FOR SPOILT MILK DETECTION

The main objective of this project is to build an electronic nose and implement it for desired application. This report is about the study of an electronic nose and its application to differentiate between the spoiled milk with fresh milk. Electronic nose is an electronic instrument that imitates the function of human nose to detect the smell, odors and flavor. Electronic nose has a wide range of applications where one of them is to discriminate foods by their quality. By using an electronic nose, it is possible to differentiate between fresh milk and spoiled milk without even have to risk our health to taste it by ourselves. The milk where it contains certain type of micro bacteria undergoes certain chemical processes which cause it to spoil and release certain gas as results of the process. The scope of this project is to do research about electronic nose, building an electronic nose for our application and perform a data analysis. The method is explained further inside this report and experiment were done to validate the findings in literature review. The experimental results are presented.
