Irrigation is the process of artificially supplying water to land where crops are cultivated. Traditionally Hand pumps , canal water and rainfall were a major source of water supply for irrigation. This method has led to severe drawbacks like under irrigation, over-irrigation which in turn causes leaching and loss of nutrient content of soil. Changing environmental conditions and shortage of water have led to the need for a system which efficiently manages irrigation of fields. Automated irrigation system is a machine based system, which automates the irrigation of land by combining various software and hardware approaches together for field irrigation. The project aims at automatic irrigation system for controlling a motor. Soil moisture sensor is used to measure the amount of moisture content present in the soil and the water sensor is used sense water availability resource in a tank. Sensor output data can be fed into the micro controller; it acts according to the control algorithm. The two GSM module is used in the network can act as transmitter and receiver is used for communication purpose. Here when a particular moisture level reaches below the threshold value, the motor will be turned ON. When a moisture level reaches above the threshold value, the motor will be turned OFF. The soil moisture content and the motor functionality status can be monitored in LabVIEW. The same webpage can be created in other PC via LAN connection.
