RELEVANT PRIOR ART OF THE INVENTION
Water purification is a process of removing undesirable contents such as chemicals, biological contaminants, suspended solids and gases and so on from water, so as to make water suitable for drinking purpose. Water consists of a lot of impurities classified as the Total Dissolved solids (TDS) that is referred to any minerals, salts, metals, cations or anions dissolved in water. This includes anything present in water other than the pure watpr (H?0\ molecule and susDended solids. (Suspended solids are any particles/substances that are neither

dissolved nor settled in the water, such as wood pulp.). In general, the total dissolved solids concentration is the sum of the cations (positively charged) and anions (negatively charged) ions in the water. Sources of these dissolved solids that make up the impurities are known in the prior art. TDS is the agreed regulation to measure the quality of drinking water. When TDS levels exceed 500mg/L it is generally considered undesirable for human consumption. A high level of TDS is an indicator of potential concerns, and warrants further investigation. More over High TDS results in undesirable taste which could be salty, bitter, or metallic. It could also indicate the presence of toxic minerals.
Household water treatment systems have gained widespread popularity, particularly in areas with less-than-ideal potable water. A household system or unit is mounted on a single tap to selectively treat water flowing through the tap and help tackle the problem with the TDS and quality of water. Different water purification technologies are available today in the market including the ultra-filtration, Reverse Osmosis, Nano filtration, Ultraviolet filtration etc. However, the consumer are not able to chose on the accurate and appropriate water purification technology that is best suited to the purification of the water based on the TDS( total dissolved solids).
The present invention solves the above disadvantage by providing an integrated water quality sensor with water purification technology /product identification device for providing from a predetermined selection of water purifiers based on the output of the said water quality sensor.
BRIEF DESCRIPTION OF THE FIGURES
The embodiments herein will be better understood from the following detailed description with reference to the drawings, in which:
FIG. 1 illustrates a general block diagram of integrated water quality sensor device and product identification device, as disclosed in the embodiments herein;
DETAILED DESCRIPTION OF EMBODIMENTS
The embodiments herein and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. Descriptions of well-known components and processing techniques are omitted so as

to not unnecessarily obscure the embodiments herein. The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.
The present invention relates to a water quality sensor device, more particularly to an integrated water TDS (Total Dissolved Solids) sensor with product identification device for providing from a predetermined selection of water purifiers based on the output of the said water quality sensor. The said integrated water quality sensor and product identification device comprises at least more than one sensor operatively coupled to a controller, where in the controller is configured to receive a measured input from one or more sensors and a wireless communication device coupled to the controller.
Further, the wireless communicator device is configured to communicate with a co-ordinator more particularly a remote network to store the information received from said one or more sensors. In various embodiments, the one or more sensor includes a total dissolved Solids sensor and a temperature sensor to sense the quality of the input water.
The one or more sensor of the present invention is a water quality sensor, more particularly a TDS sensor. The dissolved solids suspended in water are charged ions that posses property of electrical conductivity. The conductivity in water is determined by the number of charge carriers, i.e., the dissolved solids, how fast they move, and how much charge each ions carries. Thus, for most water solutions, the higher the concentration of dissolved salts, this will lead to more ions, the higher the conductivity.
The said TDS sensor of the present invention designed to measure the TDS (Total dissolved salts) in an input water sample. The said sensor measures the electrical conductivity of the water sample. Pure water has very low electrical conductivity. Impure water shows higher conductivity due to separation of ions. This conductivity is measured and converted into TDS (Total dissolved salts).
Conductivity of the water is measured by applying a voltage (AC) to a non-reactive probe immersed into the water sample. An alternating current is applied to prevent ions from depositing on the electrodes. A potential divider network is formed using a resistor and the probe. On immersing the said sensor probe in the water, Positively charged ions (e.g., sodium, Na+; calcium, Ca++; magnesium, Mg++; hydrogen ion, H+; etc.) will move towards the negatively charged electrode, and negatively charged ions (e.g., chloride, CI-; sulfate, S04-; bicarbonate, HC03-; etc.) will move towards the positively charged electrode and the voltage of the network drops. This voltage drop is measured and converted into TDS (in ppm). The non-reactive probe that forms a part of the sensor is an electrode that measures electrical conductivity.
It is also known in the art that that the conductivity of ions in water depends upon temperature of the input water. There are a number of factors that cause this effect, wherein the ions that are naturally moving around faster releases minimal heat. When the same numbers of ions are moving faster, the apparent conductivity is

increased. The relationship between conductivity and temperature is complicated and dependent on the solution being tested. Pure water responds fairly linearly with temperature, with its conductivity rising by 4.55% for every degree Centigrade (2.5% per degree Fahrenheit). One or more sensor of the present invention is a temperature sensor that measures the temperature of the input water and is used in calibrating the accurate TDS of the input water.
The data provided by the said TDS sensor and the temperature sensor is transmitted to the said controller. The said controller in the preferred embodiment calibrates the temperature and TDS input based on the predetermined algorithm. The Controller unit further comprises a data storage system such as a Flash memory card to store the output value.
The data provided by said TDS sensor of the present invention generates a water quality report that details on the quality of the input water via the predetermined algorithm. The water quality report includes parameters such as hardness of the input water, possible heavy metal contamination, possible contaminants and bacteria in the water or the like. The water quality report is further stored with additional information such as name of the individual, the date and time stamp and location of the input water.
Furthermore, the controller is configured to send the received water quality report to a wireless communication device coupled to the said controller. In one embodiment, the data is collected and transmitted to an intermediary device co-ordinator, which then transmits the signal to a gateway or network and/or other repository via wireless or wired communications.
In another embodiment, the wired communication device enables to select from a pre determined selection of water purifier based on the TDS of the input water. The wired communication is preferably a Mobile phone, a smart phone, a tablet device or the like.
The embodiments disclosed herein can be implemented through at least one software program running on at least one hardware device and performing network management functions to control the network elements. The network elements shown in Fig. 1 include blocks which can be at least one of a sensor device, or a combination of sensor device and wireless communication device with the software module.
The predetermined algorithm further displays on the screen of the wired communication device, the list of purification technologies available for the suitable purification of the input water. The list of predetermined water purification technologies includes Ideal water purification, U.V (Ultra Violet) based purification technology, Reverse Osmosis based purification technology, and Nanofiltration based purification technologies and/or the combinations of the same. The said predetermined algorithm further displays the products available for each of the purification technologies and details including cost and effectiveness for suitable purification of the input water.
In a typical example, if the TDS of the input water is beyond 500 ppm, then the wireless communication device provides a selection of water purifier based on R.O. membrane, and combinations of Reverse Osmosis

membrane and Ultraviolet radiation unit. Also, in another typical example, if the TDS of the input water is beyond 300 ppm, then the wireless communication device provides a selection of water purifier based on Ultra filtration unit and combinations of Ultraviolet radiation unit.
In accordance with the various embodiments, a quality monitoring method can include receiving, by a sensor device, Total dissolved solids (TDS) data of a stored fluid from a TDS sensor in real-time; transmitting, by the sensor device, the TDS data to a coordinator and enabling the selection of water purification technology predetermined based on the input TDS levels.
Furthermore, in various embodiment, a method comprises receiving data from one or more sensors, wherein the one or more sensors is a TDS sensor and/or a temperature sensor, which is in communication with a holding tank to receive the input sample; Using the data to populate the accurate TDS or water quality of the input water sample; enabling the user to select from a list of predetermined choices of water purifier technology based on the TDS of the input water.
