Ground Water Monitoring System using Outflow of Motor

:- Agriculture is one of the foremost necessary sectors for the Indian economy contributing 5 billion rupees towards our national gross domestic product. In the present scenario, farmers cannot support their families having two square meals a day, due to lack of rainfall and depleting underground water table. The main aim of the project is to monitor the groundwater level automatically if the water level depletes the pump will not have any water to pump. this in turn heats the pump which relies on the groundwater for its cooling. Consequently, leading to the failure of the pump's motor. The ancient methodology for finding water level in every bore well from the bottom is by measuring the time taken for a very little stone to strike the water surface. Then we will able to estimate the depth of water in bore wells. we estimate the water in a very bore well by another different methodology employing a longer skinny nylon rope, however, our estimation cannot be 100% success which ends up damaging the motor. In this project, we are employing a microcontroller, pressure sensor, and flow sensor at the discharge end. Based on the pumps rated output we will be able to continuously measure and compare the output flow and pressure. If there is any deviation in the output pressure and flow through the microcontroller we can switch the motor off/on.


1.INTRODUCTION
Agriculture is the backbone of the rural population in India. Around eightieth of the world is beneath rain-fed irrigation, that plays a serious role in world food provide. The water could be a scarce artifact associate degreed it should be employed in agriculture judiciously and economically with the target to get higher economic returns while not jeopardize the long run property. water plays a crucial role in agriculture because it is a reliable supply than surface water for irrigation. though agriculture remains the foremost necessary economic activity of rural households. In India, most of the farmer's going away the lands barren thanks to lack of water for irrigation as a result of the failure of bore wells. The severity of water deficiency for irrigation has drawn the eye of the many researchers towards development, conservation, and management ways of water. several new developments came about for changing flood irrigation to the pressurized irrigation system, porous pipe irrigation, preciseness farming, etc. for protective water. Even though the Anantapur district falls beneath the country region, agriculture remains the necessary supply for economic activity. So, irrigation is obligatory to guard the rain-fed crop. The institutional approach to managing groundwater by impressive over-exploitation of groundwater and for mitigating environmental consequences is thru the institution of a regulative framework. small irrigation is that the advanced irrigation technology for the arid and dry regions because it is appropriate for pretty much all crops, terrains, soils, and weather conditions. small irrigation system performance depends on optimum operational pressure and also the irrigation schedules. Irrigation scheduling is the guide for the farmers to irrigate and the way a lot of time to satisfy the crop water demand. The provincial government of the European nation has started Irrigation consultative services for filling the gap between the technology and followed by the farmer by providing areas, the operational schedules for a neighborhood of one lakh HA in water scarcity. Groundwater has emerged to occupy a dominant place in India's agriculture and food security in recent years. Since the expansion in groundwater irrigation has not been for the most part government or policy-driven and went on primarily through extremely localized personal activity, the groundwater revolution has passed by and huge unremarked. However, despite its Brobdingnag Ian significance and importance, groundwater irrigation is heading for a crisis and desires pressing attention and understanding India. the number of irrigation blocks labeled as overexploited is increasing at an associate degree dire rate of five percent each year. The system that manages the groundwater resource can have serious implications for the long-run growth and development of the water resources in India.
2.LITERATURE SURVEY The growth of the Motor and also the Pump business started throughout the first 1920s by the Kirloskar brothers limited company and has been quite commendable since then. the primary Submersible pump was developed within the year 1928 in Indian city Coimbatore. The PSG Industrial Institute and Dhandayudhapani manufacturing plant of Coimbatore was the pioneers within the field of pump producing and also the 1st motor was free at Argus in 1937 [1]. The input for growth came primarily from the stress on the development of the agriculture sector and also the strengthening of the economic sector throughout the serial five-year plans. after the primary five-year plan amount, heaps of stress was placed on agriculture and rural electrification, that semiconductor diode to incredible growth within the Pump business. The '70s will be thought of because of the golden era as away because the Pump business is bothered, and notably for Coimbatore. From 1991 to 1996, the expansion of the Pump business was driven largely by the boom in industries and urbanization thanks to the liberalization International Journal of Engineering Research & Technology (IJERT) ISSN: 2278-0181 http://www.ijert.org policy. Here the survey will be done supported the motor connected issues, estimation of underground water, supported seasons, supported regions as given below.

ISSUES ASSOCIATED WITH BOREWELLS:
Normal water well forms of submersible motors unit, water crammed, and admit motor because of the internal lubrication for the motor. These motors are extraordinarily reliable once applied among their style limits of temperature. once the motor works quite to thirteen to fifteen min it ends up in failure. they only check water level supported the water force from the pipe and farmer knowledge, sound, depth measured by wire over and over their predictions could fail at the ending of water levels it should end up in failure of their motor. Submersible pumps a lot of at risk of harm than jet pumps. Pumps cooled and lubricated by the water flowing through them. The impellers of a submersible pump can quickly begin to soften and fuse along once the water level drops below the intake screen of the pump. Running while not water even just the once will cause the pump to lock up or seriously degrade the pump's performance.

GROUNDWATER LEVEL BASED ON LANDS:
exaggerated in mothproof space because of urbanization ends up in shriveled infiltration and at last poignant the groundwater storage. because of the increase of settlement space can directly impact the decrease of the water level. correct land use coming up with and Groundwater management is vital to the socio-economic upliftment of an area. once there's a downfall in a region the storage of underground water in the main depends upon the condition of the soil or we can say that depends on the sort of soil. this can be observed from water-resource management, however, the drawback is that if the principal establishments concernedagriculture, water resources, environmental coming up with, local government, land use administration, and water-service utilitiesoperate in separate 'soils' with ill-defined and poorly articulated linkages and interactions as regards groundwater.

GROUNDWATER LEVEL BASED ON SEASONS:
the target of this study is to research the seasonal fluctuation of the water table by mistreatment determined knowledge on groundwater, downfall and stream result June 2015 to 2016 and remote sensing knowledge derived from the Gravity Recovery and Climate Experiment and also the international Land knowledge Assimilation System for the amount of June 2015 to March 2016 [2]. The results show that the water table exaggerated to the height elevation throughout the late wet season and it started declining from Gregorian calendar month till reached rock bottom elevation throughout the late season. The results of this analysis additionally showed a smart correlation between the soil wetness from GLDAS and water table mensuration at a GRACE footprint and also the equivalent water height derived from GRACE at a GRACE footprint with a pair of the worth of 0.72. Therefore, concerning the results of this study, additional investigation mistreatment of this remote sensing knowledge for groundwater study during this region are going to be disbursed to support in groundwater study for Southern Laos. The water table could be a key parameter for evaluating spatial and temporal changes in groundwater environments [3]. The water table is ruled by varied factors like temperature change, as mirrored in precipitation and evaporation rates, influences the water table fluctuation. climate trends have high correlations with water table variations in southern Canadian province. So, we tend to target the influence of short seasonal variation in climate on water table during this place. The impact of climate variability on water tables may be investigated by analyzing the link between climate records and groundwater level fluctuations.

ABOUT SUBMERSIBLE WATER PUMPS:
Submersible pumps push water to the surface as critical jet pumps can drag fluids. electrical submersible pumps and centrifugal pumps operate in a very vertical position. Submersible pumps unit found in several applications. Multiple stage submersible pumps usually lowered down a borehole and most usually used for residential, commercial, municipal, and industrial water extraction, water wells, and oil wells [1].

SELECTION OF WATER PUMPS:
There are various specifications to judge during selecting submersible pumps. choosing the right pump is predominant in optimizing the success of the system. initial and foremost, submersible pumps chosen considerately to pump sort and application. Next, the utmost discharge flow should be determined. most flow refers to the best quantity of flow submersible pumps are created to handle. The system or pressure head is employed to work out the utmost flow of submersible pumps. Then, the thought has to lean to the utmost discharge pressure of the pump. This pertains to the best quantity of pressure the pump will handle. Submersible pumps are evaluated in terms of HP, a mensuration of energy. HP is a figure made at a rate of 550-foot pounds per second, equaling 745.7 watts of energy. Finally, the discharge size of submersible pumps ought to be evaluated. This price has regard to the dimensions of discharge or outlet connections of submersible pumps.

By considering the above problems we are designing automatic motor Yes, it is useful If our project will work properly then it will be helpful to the farmers

EXISTING SYSTEM:
The Asian nation is an associate agricultural country, nearly many of the folks depend on the bore wells. In some, drought conditions we might not tune in to the water in bore levels. So, this end in damage to crops and conjointly ends up in less yield.

Fig3.1: Image of drought condition
Some of the issues featured by the farmers associated with the bore wells are given below.
➢ We heard a lot of problems related to motor on/off conditions based on the water content ➢ They estimate water level based on the previous rainfall occurrence and water pressure from the pipe ➢ Based on the pressure and flow of the water they can estimate the water increases or decreases ➢ They check the pressure and flow of water manually without any devices. ➢ By considering the above things we are going to create an "automatic motor on/off "based on the water pressure Fig3.1.1: Measuring water level using tape Groundwater is the water that has penetrated the surface of the planet. If these aquifers used for water extraction or monitored by measurement, a reliable and correct water level mensuration is important. water level mensuration is commonly logged to survey associated chart formation. It is required to examine the groundwater resource, wherever it's, what proportion volume it contains, and at what depth it's settled. Separate aquifers are also settled at differing depths and so need multiple sensors for an entire water level mensuration. This water level mensuration may be recorded to work out the impact of precipitation, seasonal changes, and water extraction. water level mensuration is generally performed by a submersible pressure transmitter.

PROPOSED SYSTEM:
Here we tend to use the pressure detector and flow detector to sight the water level within the bore wells, it unendingly monitors the water pressure in bore well supported the pressure of water. The motor can run up to some extent of your time nearly ten to fifteen minutes while not water then the motor gets broken. By measure the water pressure, we will overcome the matter specified we will defend the motor in time, and conjointly, we will estimate the existence of water in bore wells wherever the automated motor ON/OFF is often done. So projected system operating is often given below 1. when the motor is started then it'll check the pressure of water flow with the assistance of pressure detector and conjointly rate flow detector. If it's but the brink pressure worth with the assistance of microcontroller the motor is often mechanically turned off.

3.
Also, if the spring water level is declined with the assistance of pressure and rate of water in the pipe the motor ON/off are often declared, specified the motor damage is often overcome. So, this, however, the pressure detector is fitted into the pipe to live the water be due the pipe is given below Fig3.2: Insertion of the pressure sensor in the pipe A water flow meter is an instrument capable of measuring the amount of water passing through a pipe. many water flow meter technologies are accessible for monitoring water activity applications, fund terms, and maintenance needs. every of those water flow meter varieties incorporates a distinctive principle of operation, overall cost-of-ownership, and specific application advantages. The volumetrical rate of the water is proportional to the motility speed of the blades. The disadvantage of mechanical water flow meters for water activity is that they'll choke once the water is dirty or contain larger particles, that end up in accumulated maintenance prices. Mechanical water meters conjointly don't work well once the water flow is low. employing lower operating pressure than needed will cause the pipe to burst and cause bodily damage, particularly if the substance is harmful. Multiply the fabric strength, in pounds per unit area, by the wall thickness of the half in inches.

DESIGN & IMPLEMENTATION
Every vane within the series forces water through a diffuser into the attention of the one higher than it. in a very typical 4-inch submersible pump, every vane can add some nine psi of pressure. for instance, a typical 10-stage pump can develop a pressure of concerning ninety psi at its outlet. The capability of the pump is set by the dimension of the vane and its pressure by the number of impellers. As an example, a 1/2 H.P. 7-stage pump might deliver a high volume of water at certain pressure whereas a 1/2 H.P. 14-stage pump can deliver a lower volume however at a bigger pressure. Like all different centrifugal pumps, a rise in good depth or discharge pressure can scale back the capability. If a pump is capable of manufacturing wellhead pressure in way over 80-100 psi, an emergency pressure regulator is also required, simply just in case, the pressure switch fails within the on position. The size and type of drop pipe used for a submersible installation depend on the following: 1.
Depth to the water and pumping level.

2.
The pressure that the pump can develop.

3.
Allowable friction loss in the drop pipe.

4.
Weight of the pump 5.
Flow demand varies The work of the relay is to protect the electrical instruments and motors from overvoltage and underneath voltage and emergency power provide change.
In the 5v observation relay, the measured voltage exceeds the most allowed voltage, the tripping delay time starts to run. As presently as voltage values come back below the outlined level, the relays shut once more. Overvoltage generates heat which can injure a lot of sensitive elements in any appliances. underneath voltage might cause a voltage to vary that's undefined for your instruments, which can lead to controlled failure of individual elements.

Fig4.2: alerting through yellow indication
It works on the principle of hall effect, a voltage distinction is induced in a conductor cross to the electrical current and also the magnetic flux perpendicular to that. Here the hall effect is used within the flow meter employing a little fan that is placed within the path of flowing. it's a tool that senses pressure and converts into an analog electrical signal whose magnitude depends upon the pressure applied since they convert pressure into an electrical signal they conjointly termed as pressure transducers. currently, most of the farmers deed their lands and deed their crops at the center of yield time as a result of insufficiency of water and while not having the correct steerage and acknowledgment of spring water level and this ends up in failure of the motor by warming that happens because of the free-running of the motor while there is no water. The submersible pumps unit of high value employed in bore wells. supported the depth of bore the high-powered submersible pump unit used however suddenly the motors get broken due to the decline of groundwater in bore wells. If there's low spring water level the motor gets broken which leads to a good loss to farmers.
5.RESULTS AND DISCUSSION The project AUTOMATIC MOTOR ON/OFF BASED ON GROUNDWATER LEVEL is employed to watch the water levels in bore wells with the assistance of pressure and flow detector. The setup of our project is given below is given below Yellow LED indicates that water in the used container gets reduces to a level of 25% and that shows that it reached to the height of the motor and gives the yellow indication in the container. When the water level reaches 25% it alerts the system by giving a yellow indication. Further, the motor will run continuously. The yellow indication is given below Red LED here indicates the completion of water in the used container and then the motor gets into off position. When the flow rate coming out of the pipe is less than 10% of the used container there will be an indication of red led. The water in the used container gets reduces when it flows out of the pipe and its flow depends upon the range of motor being used in the project. The readings we get here is     So, the above graph represents the above 3 tables of analyzing flow rate and water level. The point at which the 3 curves touch is taken as a threshold point at nearly 10%. based on the water level in percentages we also estimate the flow rate in percentages and also time calculated in which how much time it takes to pump the overall water in the container. At 25% of the water level, we fix a threshold flow rate value and at 10% we fix another threshold value. From the above graph, we can analyze that if water level decreases then the flow rate also decreases. So, flow rate and water level are directly proportional to each other.so when water level decreases motor level decreases, with the help of that automatic motor ON/off can be stated. So, based on this time values the recharging of groundwater takes place. 6.CONCLUSION The product developed is very much useful to the farmers which helps in detecting the water levels automatically without the involvement of any other devices. By this product, we can eliminate the burning of motor coils and pumps due to the generation of heat during lack of water. Also, this product has a very wide scope in the future because of its simplicity and cost-effectiveness.
