Optimized Water Controlling Approach for Irrigation System Based on Wireless Sensor Network and GPRS Module

Abstract: Agriculture uses most of available fresh water resources and this use of fresh water resources will continue to be increases since population growth and food demand increases. An automated irrigation system mainly designed to optimize the usage of water on agriculture because of climatic conditions which leads to lack of rains. The system has soil moisture wireless network and a wireless sensor to maintain the quality of water in three parameters- pH, conductivity and temperature. Wireless and soil moisture sensor is programmed with microcontroller based gateway which is used to control and maintain the flow and quality of water. The system which is used here is duplex communication link based on a cellular Internet interface. By using this automated system water is saved of up to 92% and produce a good yield compared with old irrigation systems.
