A DC-DC boost converter, used as an intermediate power conditioning unit plays a vital role in efficiency enhancement of SPV array and soft starting of the DC motor with proper control. The speed control of DC motor is performed by the Arduino controller. No additional control or current sensing element is required for speed control. The behaviour of proposed pumping system is demonstrated by evaluating its various performances through MATLAB/simulink based simulation study. In this work the solar power is directly boosted using Boost Converter and there is no usage of batteries and other potential Storage Devices. In addition to that there is no step up and step down process held and transformers is not used in this work and no conversion of the Supply is held. In this work the properties of the DC supply Utilized by using IOT. From the IOT control we can able to turn on and turn off. In addition to that we set a particular time or the working time of the DC pump. KEYWORDS: Solar Photovoltaic, Embedded System, Hardware INTRODUCTION Solar power is pollution free and causes no greenhouse gases to be emitted after installation. Renewable clean power that is available every day of the year, even cloudy days produce some power. Return on investment unlike paying for utility bills. Virtually no maintenance as solar panels last over 30 years. Creates jobs by employing solar panel manufacturers, solar installers, etc. and in turn helps the economy. Ability to live grid free if all power generated provides enough for the home / building. Can be installed virtually anywhere; in a field to on a building. Use batteries to store extra power for use at night. Solar can be used to heat water, power homes and building, even power cars. It is safer than traditional electric current methodology. Efficiency is always improving so the same size solar that is available today will become more efficient tomorrow. Aesthetics are improving making the solar more versatile compared to older models; i.e. printing, flexible, solar shingles, etc. A. Solar Water Pumping Solar water pumping is based on photovoltaic (PV) technology that converts solar energy into electrical energy to run a DC or AC motor based water pump. The proposed work contains agricultural DC pump powered by PV modules. The conventional solar powered AC pumps have insulation failure, over heating problems. In addition to that the consumption of current is more. In AC motor while using in solar the consumption and requirement of parameters is more while compare to DC pumps. Though the initial cost is more for DC pumps it has the advantages of using lower number of components and high efficiency. Since the proposed worked is out of battery storage, maximum power point tracking technique (FUZZY LOGIC) is used to derive maximum power from PV module. This work deals with the utilization of solar photovoltaic (SPV) energy in the brushless DC (BLDC) motor driven water pump. A DC-DC boost converter, used as an intermediate power conditioning
