Abstract The local water supply is necessary in day-to-day life, but the water is not evenly distributed to all the people, also the children and old age people are affected by drinking the impure water because of the water tank not being cleaned properly and in correct time. In order to overcome these problems in local water supply, this project (SMART WATER SUPPLY using LABVIEW and ARDUINO) is designed. This project includes even distribution of water in local area along with tank level monitoring and controlling and tank cleaning notification and controlling. The hardware includes flow sensor, solenoid valve, turbidity sensor, transmitter, receiver, level sensor. The software includes Labview, VIPM and Arduino. Using this project, distribution of pure water evenly to all the people in local areas can be achieved.

I. INTRODUCTION This project is mainly drafted in order to supply water regularly for the localities. This project mainly concentrates on cleaning the water and removing the contaminants and distributing the water evenly to the people. The project is also added with additional monitoring the water level inside the tank and notification is sent using the transmitter and receiver in order to monitor the cleanliness of the tank and controlling it. The aim of the project is to:  To supply the water evenly to all the people in local areas using Labview.  Tank level monitoring and controlling continuously using Labview.  Tank cleaning notification and controlling using Labview. The hardware modules which were used in building this project are Flow sensor, solenoid valve, turbidity sensor and level sensors. The existing model provides water to all localities without controlling the amount water being supplied. Hence there is a risk that the water might be wasted and the other areas might not be supplied with enough water. The disadvantage of the previous project has been overcome by using the Particular area control which ensures that all the localities are equally supplied with enough water. Transmitters and receivers are used in order to ensure the cleanliness of the tank by sending and receiving the notifications. This project provides a satisfactory a solution for a long lasting problem.

II. HARDWARE MODULE The flow sensor is used in order to effectively measure the flow rate of the fluid. The level sensor is fixed along with the flow sensor to determine the level of the water. In order to check the amount of cleanliness, turbidity sensor is used along with the level sensor. The Arduino uno board is programmed along with Labview which will determine the how much amount of water should be supplied to the areas and at what time. This process is totally automated and there is no need for the user intervention. The output of the Arduino uno board is directly given to a transmitter which is placed along with a receiver which in turn is connected to a solenoid valve, supply pump and drain pump.

There are two different process involved in the cleaning process 1.

Flow meter TX RX Arduino LABVIEW  Arduino TX RX Solenoid valve The output of the flow meter is fed to the transmitter and receiver section. This output is given to the Arduino where the simulation is done with the help of Labview software. Once the simulation (checking the turbidity of the water) is done, the output is directly fed to the solenoid valve via transmitter and a receiver.


Level Sensor  TX RX Arduino LABVIEW  Arduino TX RX  supply pump control switch. The level sensor’s output is given to Arduino board with the help of Transmitter and receiver which is simulated with the help of Labview software. In order to control the supply from the pump, there is a supply pump control switch which helps to achieve the objective. The output of the Labview is fed to the supply pump control switch with the help of transmitter and receiver.

Working of Flow meter used: This sensor sits in line with your water line and contains a pinwheel sensor to measure how much liquid has moved through it. There's an integrated magnetic Hall Effect sensor that outputs an electrical pulse with every revolution. The Hall Effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry. The sensor comes with three wires: red (5-24VDC power), black (ground) and yellow (Hall Effect pulse output). By counting the pulses from the output of the sensor, the calculation of water flow is done. Each pulse is approximately 2.25 milliliters. Note this isn't a precision sensor, and the pulse rate does vary a bit depending on the flow rate, fluid pressure and sensor orientation. It will need careful calibration if better than 10% precision is required. The pulse signal is a simple square wave so its quite easy to log and convert into liters per minute using the following formula. Pulse frequency (Hz) / 7.5 = flow rate in L/min.

Fig 3: Cleaning Notification Block diagram Principal of Compact Solenoid valve used: In compact solenoid valves, the solenoid coil is mounted directly on the enclosing tube, sealed and integral with the valve body. The moveable plunger is free to move in the enclosing tube and is normally held in position by a thrust (or return) spring. When the solenoid coil is energized, the plunger is attracted by the effect of the magnetic field and the seat, integral with the plunger, opens (or closes) the valve or the valve pilot. IV.

Theory of Operation: The sensor operates on the principle that when light is passed through a sample of water, the amount of light transmitted through the sample is dependent on the amount of soil in the water. As the soil level increases, the amount of light transmitted is decreased. The turbidity sensor measures the amount of transmitted light to determine the turbidity of the wash water. These turbidity measurements are supplied to the dishwasher controller, which makes decisions on how long to wash in all the cycles. These decisions are made based on a comparison between clean water measurements (taken at the beginning of the wash cycle) and the wash water turbidity measurement taken at the end of each wash cycle. By measuring the turbidity of the wash water, the dishwasher can conserve energy on lightly soiled loads by only washing as long as necessary. This will result in energy savings for the consumer. The result of the project is checked and analyzed with the help of Labview software and the results are verified.

RESULT AND DISCUSSION This project has successfully overcome the problem of supplying water to the localities and has come with a satisfactory solution of supplying the water at regular intervals of time using Labview and Arduino. Constant monitoring of the tank has been additionally added in order to increase and check the quality of water being supplied to the localities. If the tank is improper, notifications are sent using transmitters and receivers.

VII. PROPOSED FUTURE WORKS In future we can also detect the water level and predict whether water scarcity may come or not using Micro-strategy concept using Java programming language. The statistics can be made in a precise and accurate way that it can produce an error free output. This will be very useful for the government as they can sense the water scarcity in future and can make precautionary methods to overcome the problem. Additionally, the amount of water consumed by each and every house can be determined by a automated function using flow sensor and microprocessors. If any particular house consumes more water than the limit set, then they are given a alert message from the server thus making the system a totally automated one. VIII. CONCLUSION We have designed a smart system capable sending and controlling the water supplies across all localities. This project is of low cost and the efficiency of the project is more compared to the previous methods. Necessary action can be taken in short span of time in the case of any particular house wastes or consumes more water than the prescribed set limit. Using this project, automatic controlling and monitoring the tank level is done and the allotment signals sent to the cleaner for tank cleaning determines the tank efficiency. Thus, water supply monitoring and theft detection system was built. Using proposed system, we can make centralized water control and theft detection system. We can ensure fair water supply to all users by preventing water theft and ensuring by taking necessary action. The disadvantage of the existing system that required manpower was eliminated. This real time automation implemented in the system avoids wastage of water and reduces time. IX.
