Solar Powered Auto Irrigation System

Solar Powered Auto Irrigation SystemCAREER EPISODE 2CE 2.1 INTRODUCTIONMy second career episode describes about my endure named Solar Powered Auto Irrigation System, which deals with irrigation technique helpful for farmers. I make this project during my 7th semester of engineering. It was completed in six months semester duration. It was completed under the supervision of Prof. Ashima Kalra, electronics lecturer. I completed my Bachelors degree in Electronics and Communication from Surya School of Engineering Technology, Punjab, India.CE 2.2 BACKGROUNDSolar energy is the most abundant source of energy in the world. It is a friendly form of energy as well as an answer to energy crisis. My project solar powered irrigation organization will be useful for farmers. It just requires an initial investment and then it provides a discontinue energy and is a green way of life for energy production. This system uses solar power that drives the peeing from bore well to tank via water pump . The control condition mechanically regulates the output valve of the tank. It also controls the pay heed rate of water and optimizes it for the use of water using moisture sensor. Thus, it asks to be employ with available telecommunication technology. coiffe growth and their produce are to govern or increased right away or indirectly by automating the agricultural field that monitors and controls climatic parameters.CE 2.3The motif and goal behind opting for this project was to provide a system in which automatic irrigation can be done to plants which would help in saving water and precious time of farmers. It is designed and fabricated in such a way that it would provide fresh water to irrigate the crops to all the farmers.The idea for engage this project clicked to me when I was analyzing the problems faced in daily life by common people. And then I realized that the methods of irrigation that is used is one of the oldest technologies having various methods in it. And we always want methods that are fast, efficient, and effective to deliver adequate water to crops. So, the new Agricultural solar method would ensure that the crops are being well-kept and the farmers no longer need to slave themself to manual grind of having to carry water in their buckets.CE 2.4I made a work flow plan for my project. I divided it into various parts to process by dint of it systematically and assigned a time so that my project is completed in that period. First trample involved to do some research work on the project and abstract realization. Then analysis on the components to be used was done. Then I started to prepare a block diagram and schematic diagram of the project. I also gave time to ensure about the controller and its way of interfacing. And the last stage involved implementing the hardware and packet part and gave a troubleshoot before written material the final report thesis.CE 2.5 PROFESSIONAL ENGINEERING exerciseThe pre-implementation research wor k on the topic helped me gain knowledge on the components that are required. It involvesPIC18F4520 microcontroller it is faster than other series of microcontrollers and can also be interfaced through USB and allows to simulate the program before it can be downloaded on it.Soil moisture sensor many colly moisture sensors make a soil moisture probe that can measure the content of water in the soil. Senses the high/low train of moisture than the threshold set.Solar panel it is directly mounted on the support structure and is a photovoltaic module, a set of solar photovoltaic modules or solar thermal energy panels.liquid crystal display display used to get the details of process taking place at that time.Motor two push back ups are used to flop a rotatory movement to the irrigation system.These described above are the main building parts of my project. With the help of all these components its block diagram was prepared which is shown below.CE 2.6The next step was to put this block diagram in practical implementation. I started with soldering component parts on the circuit and interfacing the LCD, sensor, and motor to the PIC18F4520 microcontroller. It was a little labyrinthine structure and involved deep concentration as any mistake would short the whole circuit. The later part involved designing the program on MPLAB software. It is a software that runs on PC and can be used to develop applications for microchip microcontrollers. It provides a single integrated environment that can be used to write programs for embedded microcontrollers and are also known as IDE, Integrated Development Environment.CE 2.7The development cycle for writing an application enroll involves various stages. This controller allows embedded system design engineer to progress through this cycle without interruption between an array of tools. It allows engineers to concentrate on writing the code without any interruptions of separate tools and different modes of operation. The b asic development system for my project involves the below stages. Using various available tools, a code is written, in that location is a project manager who organizes all file and databases and settings information. There is some hardware or software part that is useful in connection to the targeted controller and an assembler that is used for code conversion i.e. source code to machine code.CE 2.8A flow chart was prepared based on the computer programming code that was used for my irrigation system. The steps and process along with the flow of program can be described using an algorithm asStep 1 start of the processStep 2 GSM gets the initial powerStep 3 it will check for moisture levelStep 4 if the level is more than 50%, irrigation is not requiredStep 5 irrigation is required if moisture level falls below 50%Step 6 it initializes the motorStep 7 gives a brief report about the process/progressStep 8 after the completion of complete process it goes back to the original state.CE 2.9And the final stage involved to perform a test run and troubleshooting. I tried to solve the maximum problems and errors in the software by myself. If I was unsuccessful in them, I made a list of problems and errors so that I could approach my project guide for the help and learn the technique that would be helpful in solving such errors and later implement it by myself. This type of irrigation system can be customized as per the need and the type of crop and is also having low maintenance. It is designed and developed in such a way that it can be scaled and customized for large pass around fields or for greenhouses. It has lot of scope for future expansion. One can make use of temperature monitoring in compost production or internet controlled duplex communication can be implemented which would help in taking powerful decisions. Such systems require low maintenance and attention and give long term benefits economically and is environment friendly.CE 2.10There were many stages which involved complication and trouble pursuing it. The very first and big scrap was to complete it on time. As the process and implementation was a long and tedious process it took time for making it perfect. I made lot of mistakes dapple synchronization and interfacing of the components with the controller on the circuit board which intern was a delaying my project and making it costly as many components were not interfaced properly and got broken. til now after all such problems I didnt held myself back, I went on with my project by taking steps of guidance and consulted my professors as and when needed. In the end, it was completed and was made as I planned for it.CE 2.11 SUMMARYMy project solar based irrigation system was completed on time and proved to the control system that gave real time feedback on monitoring and controlling of all the activities involving auto irrigation system very efficiently. It is a system that proved to be a work force saver, that would incur pro fit and improve the production. It is a modernized structure in the agriculture industry with the optimum expenditure. In future, pesticides and fertilizer system can be implemented and added to this system so that it can be added automatically. It can also be developed so that it would measure the ambience temperature, humidity level or light intensity required.This project was a building block in my career. It broadened my views in terms of technology and helped me develop and grow myself as an engineer and market place ready. It taught me to handle difficult situations and made me strong enough.
