Abstract: This paper presents the design and development of Arduino controller based system to detect the parameters of milk. The parameters include milk quantity, pH, CLR and SNF. The Ultrasonic sensor, pH sensor and lactometer are used to measure the quantity, pH and CLR of the milk respectively. Using the value of FAT and CLR the value of SNF can be calculated and studied qualitatively. The sensors are interfaced with the Arduino controller. The software developed enables to read the parameters and display them on the LCD panel. The milk quantity is displayed in litres. This is a low cost and efficient tool to detect adulteration of the milk.
Keywords: Milk; Adulteration; Arduino controller; pH meter, SNF, CLR.
