A serious issue that compromises consumer health, safety, and quality is milk adulteration. This paper introduces a spectroscopic system based on photodiodes that uses light intensity measurements to identify milk adulteration. The system proposes a spectrophotometer sensor-based method to analyse the transmitted light, converting it into Analogue-to-Digital Converter (ADC) values to relate to adulteration levels ranging between 10% and 100%. It requires a 10 ml milk sample to show the results in a 10-second response time and sensitivity of 10%. For this system, a total of 20 random samples were tested. For ensuring the accuracy of the detection of impurities like water, a careful calibration process was followed to match ADC values with adulteration percentages. The suggested approach offers a quick, practical, and economical way to assess the purity of milk.
