Control and Remote Sensing of an Irrigation System Using ZigBee Wireless Network

Cropping systems concerns are increasing significantly in semi-arid and arid areas. In order to maximize the productivity while saving water, the barrier of site-specific irrigation management can be solved. This is done by using in-field distributed sensor-based irrigation system. The main aim of this paper is to highlight the details and instrumentation of various controls. They are variable rate irrigation, wireless sensor network. For monitoring the real-time in-field sensing and control of a site-specific precision linear-move irrigation system a software is used. According to the soil property map, six in-field sensor stations are used to monitor the field conditions. The report of thesemonitoring data is periodically sampled and transmitted to base station. Geo-referenced location of sprinklers is updated timely with the help of logic programmable controllers [1]. ZigBee communication enables the interfacing of communication signals from sensor network and irrigation controller to the base station. Stable remote access to field conditions and monitoring and real-time control of variable rate irrigation controller is achieved. A graphic user interface-based software is used for this.
