摘要：The main aim of the project is to optimize the water which is irrigated to the paddy crop. To maintainthe moisture level of paddy crop, irrigation of water is regulated based on the climatic condition (temperature level).Analog value of all sensors is given to an ADC which will convert the analog value into digital value. and given tomicrocontroller. The sensor values are processed by the microcontroller to take appropriate decision to maintain thepaddy field moisture level. Based on the values obtained from the sensors, microcontroller either will ON or OFF thewell motor and the current status of the field is messaged to the farmer through GSM Technology. Temperature sensoris used to detect the atmosphere temperature. When the field temperature is very high, the motor is to be in OFFcondition. If the reference voltage of the level of moisture is low, Motor goes to ON state. Suppose if the referencevoltage of the level is high, then the Motor goes to OFF state. The motor can be going to ON/OFF depends upon themicrocontroller output value. Then water level sensor is used to give the information about the water level of well. Ifthe water level of well is below required level then the motor is to be in OFF condition. Otherwise the controllerswitches ON the motor and provides water to the paddy field. LCD display is used to display the determined sensorvalues and motor ON/OFF state. This display values are transmitted to the field owner whenever the system going tochange the state of functionality.
