Agriculture is the source of livelihood of majority Indians and it also has a great impact on economy of the country. In dry areas or in places where there is inadequate rainfall or when a farmer is not aware of how to use water when there is too much of water storage or when there is no water storage irrigation becomes tedious. Wireless sensor networks and their applications for precision agriculture is an automated irrigation system used to enhance the use of water for agricultural crops. The system consists of a wireless network that is the soil moisture sensor and temperature sensor placed under the soil where plants roots are reached, which is a distributed network. The system has a water level sensor which will indicate the presence of water level in tank. A gateway unit manages the information related to sensors, which triggers the actuators, and data are transmitted using GSM module.Keywords: Automation, Internet, Irrigation system, Wireless Sensor Network (WSN)Cite this Article Anusha A, Gouthami D.
