Abstract: Cost effective solar power can be the answer for all our energy needs. Solar powered smart irrigation systems are the answer to the Indian farmer. This system consists of solar powered water pump along with an automatic water flow control using a moisture sensor and GSM technology. It is the proposed solution for the present energy crisis for the Indian farmers. This system conserves electricity by reducing the usage of grid power and conserves water by reducing water losses. For the security purpose for the agriculture field cost effective laser fencing system is used. This type of security system is environment friendly and uses less power than electrical fencing. This circuit mainly consists of LDR, when there is an interrupt to the beam of laser the system produces a huge noise so that the wild animals run far away from the place. This project will be a design and implementation of a polar single axis solar panel tracker. It will have a fixed vertical axis and an adjustable horizontal motor controlled axis. This setup is similar to an office swivel chair. The tracker will actively track the sun and change its position accordingly to maximize the energy output. To prevent wasting power by running the motor continuously, the tracker will correct its position after 2 to 3 degrees of misalignment. The sensors will compare the light intensities of each side and move the panels until the tracker detects equal light on both sides. Additionally, it will prevent rapid changes in direction that might be caused by reflections, such as cars passing by. A rear sensor circuit is also incorporated to aid in repositioning the solar panels for the next sunrise. The gear motor will have overturn triggers to prevent the panel from rotating 360° and entangling wires. The motor control and sensing circuitry will run on batteries charged by the solar panel. This project will use 10W solar panels of approximately 15 inches by 10 inches to model larger panels used in industry.
