[0054] FIG. 3 illustrates an exemplary view of the proposed surveillance system for testing milk quality, in accordance with an embodiment of the present disclosure.
[0055] As illustrated in FIG. 3, the proposed system (100) can include a device, and a controller (106). The device can include a housing adapted to accommodate and receive a milk sample along with a set of sensors (104). The controller (106) can be communicatively coupled to the device. In an embodiment, the device can be a pen-shaped device, where the pen-shaped device can be connected to Internet of Things (IoT) and an user can take appropriate action as per value received by the set of sensors (104) or by message displayed on screen of one or more mobile computing devices, where the one or more mobile computing devices can be in communication with the controller (106). [0056] In an embodiment, the set of sensors (104) can include pH sensor (104-1), moisture sensor, temperature sensor (104-5), humidity sensor, alcohol sensor (104-3), air quality sensor (104-2), light intensity sensor, testing sensor (104-4), and the like. In an illustrative embodiment, pH (potential of hydrogen) is a measure of the hydrogen ion concentration in water. The milk has pH of range 6.5-6.7, above and below this range is totally considered as abnormalities in quality of the milk. In an illustrative embodiment, the pH sensor (104-1) can be configured to sense pH value of the milk sample.
[0057] Milk has specific temperature and humidity standards that can be followed during storage. If the milk is mixed with water or any harmful elements,

the temperature cannot remain within normal range. Milk is generally safe at
temperatures between 35 and 40 degrees Fahrenheit, above or below which
bacterium growth occurs and can be unfit for drinking. In an illustrative
embodiment, the temperature sensor (104-5) and the humidity sensor can be
configured to sense temperature and humidity of the milk sample and can send
information pertaining to the temperature and humidity to the controller (106).
Alcohol presence in milk can be tested by adding 5 ml milk with 5 ml of ethanol
solution. If the tested milk is of good quality, there will be no coagulation, clotting
or precipitation. Presence of flakes or clots indicates poor quality milk. In another
illustrative embodiment, the alcohol sensor (104-3) can be configured to sense
ethanol in the milk sample and transmit information to the controller (106).
[0058] Odor concentration can vary from fresh milk to poisonous milk. When
toxicity of milk is high, the milk can emit toxic gases, which manifest as an unpleasant odor in the milk when the milk is stored for an extended period of time or due to external contamination. The air quality sensor (104-2) can be configured to detect gases emitted by the milk sample, which are unpleasant odor in general. [0059] Taste is something which can depend on the pH and conductivity of particular substance as adulterants are added to the milk and can have different conductivity. Conductivity of solution depends on concentration of all ions present. Greater the concentration greater can be the conductivity. As pH is a measure of H+ ions, for an acidic solution pH can be lower [higher H+ ions], and greater can be the conductivity. Similarly higher the pH lower will be the conductivity for basic solution. In an illustrative embodiment, the taste sensor (104-4) can be configured to sense taste according to conductivity and pH of the substance of the milk sample.
[0060] The data received from all the set of sensors (104) units can be received by the controller (106), and the controller (106) can be configured to send the data through the message/ email. If the milk quality is found to be poor then an online complaint can be reported and sent by the user to concerned authority of milk quality testing.

[0061] In an illustrative embodiment, the device for testing milk quality, the device can include the set of sensors (104) such as temperature sensor (104-5), humidity sensor, pH sensor (104-1), alcohol sensor (104-4), air quality sensor (104-2), light intensity sensor, and testing sensor (104-4) to sense one or more parameters of milk, and transmits the one or more parameters to the controller (106). In another illustrative embodiment, the controller (106) can be configured to analyze the received one or more parameters, and accordingly generate the set of alert signals, which are transmitted to the one or more mobile computing devices through the communication unit. The device can enable the user to give reviews and generate complain to associated authority for quality of milk. [0062] While embodiments of the present invention have been illustrated and described, it will be clear that the invention is not limited to these embodiments only. Numerous modifications, changes, variations, substitutions, and equivalents will be apparent to those skilled in the art, without departing from the spirit and scope of the invention, as described in the claim.
[0063] As used herein, and unless the context dictates otherwise, the term "coupled to" is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms "coupled to" and "coupled with" are used synonymously. Within the context of this document terms "coupled to" and "coupled with" are also used euphemistically to mean "communicatively coupled with" over a network, where two or more devices are able to exchange data with each other over the network, possibly via one or more intermediary device.
[0064] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
