Abstract
An ultrasonic sensor has been used for detecting the amount of adulteration in full cream milk with water. The sample under test is filled in a rectangular perplex glass cell, containing ultrasonic transmitter and receiver which is kept in through transmitter mode for generating the ultrasonic waves. The acoustic wave passing through the sample gets attenuated. The level of attenuation varies with the amount of adulteration with the sample of milk. Hence, the attenuation is the measure of adulteration and can be calibrated with standard adulterated milk samples with water at room temperature. The percentage of adulteration in milk is found to be linearly related with the attenuation of ultrasonic waves passing through it. The method would help in easy and quick detection of adulteration in milk, which is the need of the hour for better health care of masses.
