In India, co-operative based milk collection centerin ruralarea collect milk from farmers. Aquantity of milk tested for its quality using traditional test equipments. The fear of unhygienic conditions and milk contamination occurs mostly due to delay in testing. Possibility of human error in calculation of milk quality and quantity is also one of the threats. Therefore, a cost effective electronic system is essential at dairies. In this paper, Fuzzy logic is employed on different parameters of themilk such as FAT, Water concentration, SNS (Solid non FAT), protein and lactose for the identification ofquality of milk. (FIS) implemented by employing the data sets collected from several milk industries wherein the milk is tested using sophisticated instruments. This model is further simulated in Simulink. In hardware design,ultrasonic sensors used for FATs measurement, water concentration is measured by IR sensor to formulate the SNF (solid non FAT), Lactose and Protein. The model has shownthe different contents in milk as well asthe overall quality of milk on LCD display.
