"The project is designed to develop an automatic irrigation system which switches the pumpmotor ON/OFF on sensing the moisture content of the soil. In the field of agriculture, use of propermethod of irrigation is important. The advantage of using this method is to reduce humanintervention and still ensure proper irrigation.The project uses an 8051 series microcontroller which is programmed to receive the inputsignal of varying moisture condition of the soil through the sensing arrangement. This is achievedby using an op-amp as comparator which acts as interface between the sensing arrangement andthe microcontroller. Once the controller receives this signal, it generates an output that drives arelay for operating the water pump. An LCD display is also interfaced to the microcontroller todisplay status of the soil and water pump. The sensing arrangement is made by using two stiffmetallic rods inserted into the field at a distance. Connections from the metallic rods are interfacedto the control unit.The concept in future can be enhanced by integrating GSM technology, such that wheneverthe water pump switches ON/OFF, an SMS is delivered to the concerned person regarding thestatus of the pump. We can also control the pump through SMS."
