The aim of this project is to watering the plants of a garden when nobody present in the garden to water the plants.In this circuit a sensor part is used that uses an opamp ic LM324. The Opamp in this circuit works as a comparator. The aim is done complete by inserting two copper wires in the soil with the sensors that senses that the soil of garden near the plant is wet or dry.The microcontroller used in this circuit monitors the whole conditions and sensors.It determines that when two or more then two sensors sense the soil as dry then the motor pump will automatically switch on and the pump is switched off when the sensors are in wet condition.A software is stores in the ROM and this controls the job of microcontroller.The circuit diagram and other essential material is given in the downloading package.
