Nowadays, farmers in the agriculture field facing a lot of problems in pouring the water into their field to keep their crops green especially in summer season. It’s because they don’t have a proper idea about the power availability. Even it is available, they have to wait until the field is properly watered. Thus, this procedure checks them to stop doing other acts. But, there is a solution, namely “solar powered auto irrigation system”. In the trial of solar power based irrigation system, PV cells are used to produce electricity, that energy is stored in rechargeable batteries. The energy which is produced from the batteries is used for the system operation. A water pump is used to pump the water from a boor well to a water storage tank.
It becomes tedious to manually operate the irrigation system and keep monitoring the water level of the soil. Hence the system uses solar power by using photo-voltaic cells instead of commercial electricity. The project requires an op-amp IC that acts as comparator and senses the soil moisture level. To measure the soil moisture content two copper wires are inserted into the soil at a certain distance. The sensors send the data to microcontroller which is interfaced to relay driver IC that initiates relay to operate pump motor to switch ON/OFF and the status of the pump is displayed on a LCD screen.
