| Popis: | This paper presents an embedded system design and tests carried out in order to measure the adulteration of water in milk. The practice of adulteration is being carried out since a long time and now because of the sophistication of the methods it has become increasingly difficult to differentiate the adulterated milk from the unadulterated one. Adulteration also has serious health effects which if ignored can lead to irreparable damage of health. Many contact based methods are already in use but that leads to wastage of milk since sample cannot be reused again. Non-contact methods suffer from poor accuracy. In this paper we have used two parameters, the attenuation co-efficient and time of flight to analyze the fat content and the amount of water adulteration present in raw milk samples obtained from different dairies and skimmed milk samples with different fat content from popular Indian brands. A keypad and LCD have also been interfaced with an 8-bit ATmega microcontroller along with the sensor. The keypad and LCD provide the necessary user interface for the system. The system shows an accuracy of about 95% with a deviation of 1% either side. The misclassification accuracy obtained in the system is 2 times more than traditional methods like spectroscopy which is widely in use. |
