Adulteration in milk is a common scenario for gaining extra profit, which may cause severe harmful effects on humans. The qualitative spectroscopic technique provides a better solution for detecting the toxic contents of milk and foodstuffs. All the available spectroscopic methods for milk adulterant detection are based on laboratory-based with costly equipment. This laboratory-based detection takes a long time and is more expensive, which may not be afforded by a common man. To overcome this issue, this research work involves the design and development of a low-cost,portable, multispectral, AI-based, non-destructive spectroscopic sensor system that can be used to detect the milk adulterant in real-time. The designed sensor system uses the spectroscopic method with wavelength ranges from (410-940nm) which consists of three different bands Ultraviolet(UV), visible, and Infra-Red(IR) spectrum to improve the accuracy of detection. The sensor system is connected to the internet via the developed IoT application module, which displays the detected adulterant results in a dedicated web page designed for this purpose. This IoT application enables the adulterant detected results published on the internet immediately with location information for bringing transparency. Adulterant detection problem is formulated as a classification problem and solved by machine learning algorithms of a decision tree, Naive Bayes, linear discriminant analysis, support vector machine and neural network model. The average accuracy of linear discriminant analysis, support vector machine, Naive Bayes, decision tree and neural network model are obtained as 88.1%,90%,90%,91.7% and 92.7% respectively. Genetic algorithm framework is formulated for hyperparameter tuning of neural network model which improved the accuracy from 92.7% to 100%. The model is trained for five different classes of four adulterants, namely Sodium Salicylate, Dextrose, Hydrogen Peroxide, Ammonium Sulphate, and one pure milk sample.

INTRODUCTION N OWADAYS,food adulteration is a common scenario among shopkeepers in gaining extra immediate profits.Adulteration is added in foods like ripening mangoes, adding chalk powder on turmeric, starch on curry powder, blending papaya seeds on black pepper, etc. This adulteration venture leads to harmful effects for humans on a long-term basis. The fluid cow milk consumption is about 77.68 million metric tons in India. In December 2019, statistics showed that India plays the best role in cow milk consumption [1]. Milk has powerful nutrients such as lactose, fat, proteins, minerals, and vitamins in a significant proportion, which helps to provide a better human diet [2]. Since the peoples consume the milk daily in their diet, detection of adulterants in the milk is one of the significant research to ensure the health safety of the humans. Spectroscopy-based adulteration detection is one of the met...
Industry 4.0 initiatives include the concept of smart manufacturing with the help of sensors and intelligent systems. Smart manufacturing optimizes the internal process and decision making with no/minor intervention from humans. Nevertheless, the adoption of IIoT in industry setting remains a challenge and very minimal work has been in progress. This work is aimed to showcase adoption of IIoT in the Slip Control System/Anti-Lock Braking System. It optimizes the monitoring and decision making of various processes with the help of intelligent systems and IoT in the perspective of Industrial IoT 4.0. It mainly focuses on the various conditions and parameters such as line breakdown notifications, pressure levels, etc. They are monitored through the cloud platform and an alert system is developed in the cloud to warn the user regarding the pressure level. The instant alert of line breakdown notifications reduces the downtime of the plant, improves production and monitoring of the pressure system in the plant and safety check of the plant is in place at any instant.
